MORF4L1 Human

What is MORF4L1 and what are its primary functions in human cells?

MORF4L1 (also known as MRG15) is a member of the mortality factor on chromosome 4 (MORF4) class of proteins and belongs to a subgroup of histone acetyltransferases. It functions in several critical cellular processes including chromatin remodeling, transcriptional regulation, and DNA damage repair. MORF4L1 is a component of both the NuA4 histone acetyltransferase (HAT) complex involved in transcriptional activation through acetylation of nucleosomal histones H4 and H2A, and the mSin3A complex which acts to repress transcription through deacetylation activities. This dual functionality enables MORF4L1 to participate in both gene activation and repression depending on its binding partners and cellular context. The protein has been demonstrated to play important roles in embryonic development, cellular senescence, and DNA repair mechanisms, particularly in homology-directed repair of chromosomal breaks .

How is MORF4L1 structured and what are its key domains?

MORF4L1 is a protein with a calculated molecular weight of 41 kDa, though it is typically observed at 35-37 kDa in Western blot analyses. The protein shares 96% amino acid sequence homology with MORF4, its closely related family member. MORF4L1 contains several functional domains that facilitate its diverse cellular activities. The protein's structure enables homodimerization, which has been identified as essential for forming complexes that repress cell proliferation. This dimerization capability allows MORF4L1 to serve as a scaffolding protein in various multiprotein complexes involved in chromatin modification and DNA repair. The interaction domains within MORF4L1 facilitate its binding with numerous proteins including BRCA2, PALB2, RAD51, and RPA1, which are critical components of the DNA damage response and repair machinery .

What is the normal expression pattern of MORF4L1 across human tissues?

MORF4L1 is widely expressed across normal human tissues, with particularly notable expression in epithelial cells. In experimental studies, the normal nasopharyngeal epithelial cell line NP69 shows robust MORF4L1 expression compared to cancerous counterparts. Studies examining MORF4L1 expression typically utilize human tissues including skin and testis for immunohistochemical analyses, suggesting detectable expression in these tissues. Brain tissue from mouse models also shows MORF4L1 expression, indicating conservation across mammalian species. The protein's expression appears to be dynamically regulated during development and in response to cellular stressors like DNA damage. Understanding the normal tissue-specific expression patterns is crucial for contextualizing MORF4L1's role in disease states, particularly in cancers where its expression is frequently altered .

What are the recommended protocols for detecting MORF4L1 in experimental systems?

For MORF4L1 detection, multiple validated approaches are available. Western blot analysis using antibodies such as the polyclonal 55257-1-AP antibody at dilutions of 1:500-1:1000 has proven effective for detecting MORF4L1 in HEK-293 cells, A549 cells, and mouse brain tissue. For immunoprecipitation studies, researchers can use 0.5-4.0 μg of antibody for 1.0-3.0 mg of total protein lysate. Immunohistochemistry can be performed with antibody dilutions ranging from 1:50-1:500, with successful detection demonstrated in human skin and testis tissues. For optimal antigen retrieval, TE buffer at pH 9.0 is recommended, though citrate buffer at pH 6.0 may serve as an alternative. RT-qPCR can be utilized with validated primers such as forward 5′-AGCAATGTTGGCTTATACACCTC-3′ and reverse 5′-AGCTTTCCGATGGTACTCAGG-3′, with GAPDH as a reference gene. Storage of antibodies should be at -20°C in PBS with 0.02% sodium azide and 50% glycerol at pH 7.3 for optimal stability and performance .

How can researchers establish stable cell lines with modified MORF4L1 expression?

To establish stable cell lines with altered MORF4L1 expression, researchers can employ lentiviral transduction systems. For overexpression, the full-length cDNA of human MORF4L1 can be cloned into expression vectors such as pSin-puro. For knockdown studies, shRNA targeting MORF4L1 with validated sequences such as 5′-GTTGCCATAAAGGACAAACAA-3′ can be cloned into vectors like pFCL2.0. The recombinant plasmids (3 μg) should be co-transfected with packaging plasmids pMD2.G (3 μg) and psPAX2 (3 μg) into 293 cells. After 48 hours, collect the virus-containing supernatant and add it to target cells supplemented with 8 μg/ml polybrene. Incubate for 24 hours at 37°C before selecting stable transfectants using puromycin (1 μg/ml) for approximately two weeks. This approach allows for the generation of stable cell lines with consistent MORF4L1 expression modifications, enabling long-term functional studies. Validation of expression changes should be performed using Western blot and RT-qPCR to confirm successful modification of MORF4L1 levels .

What functional assays are appropriate for studying MORF4L1's role in cell migration and invasion?

Several well-established functional assays can effectively evaluate MORF4L1's impact on cell migration and invasion. For migration assessment, the transwell migration assay is recommended, where 8×10^4 cells are resuspended in 200 μl serum-free medium and added to cell culture inserts with 8-μm microporous filters. Complete medium with serum is added to the bottom chamber as a chemoattractant, and cells are allowed to migrate for 24 hours before quantification. For invasion studies, the same approach is used but with Matrigel-coated inserts to provide an extracellular matrix barrier. The wound healing assay offers complementary data on cell motility, where confluent cell monolayers are scratched with a 200-μl pipette tip and wound closure is monitored at 0, 24, and 48 hours. For both assays, quantification should involve counting cells in at least three randomly selected optical fields (×100 magnification) from triplicate samples. These methodologies have successfully demonstrated MORF4L1's inhibitory effects on cell migration and invasion in nasopharyngeal carcinoma models and can be adapted for other cancer types .

How is MORF4L1 expression altered in human cancers and what mechanisms drive these changes?

MORF4L1 expression is significantly downregulated in multiple cancer types compared to their corresponding normal tissues. This pattern has been consistently observed in nasopharyngeal carcinoma (NPC), where RT-qPCR analysis demonstrates reduced MORF4L1 mRNA levels in both clinical samples and cell lines compared to normal nasopharyngeal epithelium. Similar downregulation patterns extend to breast, colon, and lung cancers based on analyses from The Cancer Genome Atlas data. The primary mechanism driving this reduced expression appears to be epigenetic, specifically promoter hypermethylation. Analysis of the MORF4L1 promoter region reveals the presence of CpG islands that show significantly higher methylation rates in tumor cells compared to normal cells. This methylation pattern was confirmed using the MethHC database, which integrates DNA methylation and gene expression data. This hypermethylation mechanism may represent a common feature across different cancer types, suggesting that epigenetic silencing of MORF4L1 could be a contributing factor to cancer initiation or progression .

What evidence supports MORF4L1's function as a tumor suppressor?

Multiple lines of experimental evidence establish MORF4L1 as a tumor suppressor gene, particularly in nasopharyngeal carcinoma. Functional studies demonstrate that ectopic expression of MORF4L1 in cancer cell lines significantly inhibits cell proliferation, colony formation, migration, and invasion capabilities. Conversely, knockdown of MORF4L1 using shRNA enhances these malignant phenotypes, further confirming its tumor-suppressive role. Mechanistically, MORF4L1 appears to exert its tumor suppressor function by increasing the levels of p21, a critical cell cycle inhibitor, and E-cadherin, a cell adhesion molecule often lost during epithelial-mesenchymal transition and cancer progression. The upregulation of these proteins contributes to cell cycle arrest and maintenance of epithelial integrity, respectively. Additionally, MORF4L1's involvement in DNA repair pathways through interactions with BRCA2, PALB2, and RAD51 suggests a role in maintaining genomic stability, another crucial aspect of tumor suppression. The consistent downregulation of MORF4L1 across multiple cancer types further supports its classification as a tumor suppressor gene .

How does MORF4L1 influence cell migration and invasion in cancer models?

MORF4L1 demonstrates significant inhibitory effects on cancer cell migration and invasion capabilities, critical processes in metastasis. In nasopharyngeal carcinoma cell models, overexpression of MORF4L1 significantly reduces both migration through microporous membranes and invasion through Matrigel-coated barriers, while knockdown of MORF4L1 accelerates these processes. In wound healing assays, MORF4L1-overexpressing cells show reduced motility and delayed wound closure compared to control cells. The molecular mechanism underlying these effects involves MORF4L1's ability to upregulate E-cadherin expression. E-cadherin is a key cell adhesion molecule that maintains epithelial integrity and its loss is a hallmark of epithelial-mesenchymal transition (EMT), a process that enables cancer cells to acquire migratory and invasive properties. By promoting E-cadherin expression, MORF4L1 helps preserve epithelial cell-cell contacts and prevents the acquisition of mesenchymal-like, invasive phenotypes. This mechanism establishes MORF4L1 as a potential negative regulator of metastasis, particularly in epithelial cancers where loss of E-cadherin expression is closely associated with invasive progression .

How does MORF4L1 contribute to DNA double-strand break repair?

MORF4L1 plays a significant role in homology-directed repair (HDR) of DNA double-strand breaks through its interactions with key components of the DNA repair machinery. Research indicates that MORF4L1 physically and functionally associates with BRCA2, PALB2, RAD51, and RPA1, which are essential proteins in the DNA damage response and repair pathway. These molecular interactions facilitate the recruitment and function of the repair complex at sites of DNA damage. Specifically, MORF4L1 stimulates homology-directed repair of chromosomal breaks, a high-fidelity repair mechanism that helps maintain genomic integrity. Experimental evidence from murine models demonstrates that Mrg15-deficient (MORF4L1 ortholog) embryonic fibroblasts exhibit moderate sensitivity to γ-irradiation, a DNA-damaging agent. These cells also show reduced formation of Rad51 nuclear foci following irradiation, indicating impaired recruitment of repair machinery to damaged DNA sites. Studies in C. elegans further support this role, as mutants of MRG15 and BRCA2 orthologs show similar phenotypes including accumulation of RPA-1 nuclear foci and aberrant chromosomal compactions in meiotic cells, suggesting conserved function in DNA repair across species .

What is the relationship between MORF4L1 and the Fanconi anemia/breast cancer susceptibility pathway?

MORF4L1 has been identified as a component interconnected with the Fanconi anemia (FA) and breast cancer (BrCa) susceptibility pathway, a critical DNA damage repair signaling network. Protein interaction screening revealed that MORF4L1 physically interacts with key proteins in this pathway, particularly BRCA2, which is encoded by a gene implicated in both Fanconi anemia and hereditary breast cancer. These interactions position MORF4L1 as a potential collaborator in the cellular response to DNA damage, specifically in the repair of DNA crosslinks and double-strand breaks. The functional significance of these associations is supported by observations in model organisms, where defects in MORF4L1 orthologs produce phenotypes resembling those seen in FA/BrCa pathway mutations. The connection to this pathway suggests that MORF4L1 may contribute to genome stability maintenance and could potentially influence cancer susceptibility, particularly for cancers associated with defects in DNA repair mechanisms. This relationship highlights the importance of considering MORF4L1 in the broader context of DNA repair networks and their implications for cancer development and treatment .

How can researchers experimentally assess MORF4L1's function in DNA repair pathways?

To evaluate MORF4L1's role in DNA repair, researchers should implement a multi-faceted experimental approach. DNA damage sensitivity assays can be performed by treating control and MORF4L1-modified cells (overexpression or knockdown) with DNA-damaging agents such as γ-irradiation, measuring cell survival through clonogenic assays or MTT/XTT viability tests. Immunofluorescence microscopy is essential for visualizing the formation of DNA repair protein foci, particularly RAD51 and RPA1 foci, following DNA damage induction. Co-immunoprecipitation and proximity ligation assays can identify physical interactions between MORF4L1 and key repair proteins like BRCA2, PALB2, and RAD51. Homology-directed repair efficiency can be quantified using reporter constructs containing GFP sequences that are activated upon successful HDR. Chromatin immunoprecipitation can determine MORF4L1 recruitment to damaged DNA sites. Additionally, analysis of chromosomal aberrations using metaphase spreads provides insights into genomic stability. Combining these approaches enables comprehensive characterization of MORF4L1's contributions to DNA repair mechanisms and genomic integrity maintenance. For model organisms, C. elegans systems can be particularly valuable as they allow assessment of phenotypes like RPA-1 foci accumulation and chromosomal compaction in meiotic cells .

How do MORF4L1 mutations or variants influence cancer susceptibility?

The relationship between MORF4L1 genetic alterations and cancer susceptibility remains an evolving area of research. While direct causative mutations in MORF4L1 have not been widely reported in familial cancer studies, its functional connections to known cancer susceptibility genes like BRCA2 suggest potential involvement in modifying cancer risk. Research has explored MORF4L1 mutations in patient cohorts, including analysis of 300 familial breast cancer patients negative for BRCA1/2 mutations and 13 Fanconi anemia cell lines, though significant genetic alterations were not identified in these specific studies. The protein's role in DNA repair pathways, particularly through interactions with BRCA2, PALB2, and RAD51, positions it as a candidate modifier of cancer risk, especially in contexts of DNA repair deficiencies. Reduced MORF4L1 expression due to promoter hypermethylation appears more common than genetic mutations across multiple cancer types. Further investigation using larger cohorts, genome-wide association studies, and functional validation of identified variants is needed to fully elucidate how MORF4L1 genetic alterations might influence cancer susceptibility, potentially opening avenues for improved risk assessment and personalized prevention strategies .

What are the current challenges in studying MORF4L1's chromatin remodeling functions?

Investigating MORF4L1's chromatin remodeling activities presents several methodological challenges that researchers must address. MORF4L1 participates in at least two distinct chromatin-modifying complexes—the NuA4 histone acetyltransferase complex that activates transcription and the mSin3A complex that represses transcription—making it difficult to isolate its context-specific functions. This dual role necessitates sophisticated approaches to distinguish when and how MORF4L1 contributes to either activation or repression of gene expression. Techniques like ChIP-seq (Chromatin Immunoprecipitation Sequencing) can map MORF4L1 genomic binding sites but require highly specific antibodies and optimal fixation conditions. ATAC-seq (Assay for Transposase-Accessible Chromatin with sequencing) can reveal how MORF4L1 influences chromatin accessibility but may not directly connect to functional outcomes. Proximity-dependent biotinylation (BioID) or APEX approaches offer promise for identifying context-specific protein interactions in living cells. Additionally, single-cell approaches are increasingly important to capture the heterogeneity of MORF4L1's chromatin functions across different cell states. Integrating these techniques with gene expression analysis and functional assays is essential for comprehensive understanding of MORF4L1's complex role in chromatin biology .

What emerging therapeutic strategies might target MORF4L1 in cancer contexts?

Emerging therapeutic strategies targeting MORF4L1 in cancer contexts center on its tumor suppressor properties and role in DNA repair mechanisms. Given that MORF4L1 is frequently downregulated in various cancers due to promoter hypermethylation, epigenetic modifying agents such as DNA methyltransferase inhibitors (e.g., 5-azacytidine) represent a potential approach to restore MORF4L1 expression and function. Another promising strategy involves synthetic lethality approaches, particularly in tumors with deficiencies in DNA repair pathways. Since MORF4L1 interacts with BRCA2 and participates in homology-directed repair, inhibiting complementary repair pathways might selectively target cells with altered MORF4L1 expression. The development of small molecules that modulate MORF4L1's interactions with its protein partners could also provide therapeutic opportunities, either by enhancing or disrupting specific protein complexes depending on the cancer context. Gene therapy approaches to restore MORF4L1 expression in tumors where it is silenced might reestablish its tumor suppressor functions. Additionally, understanding how MORF4L1 status affects response to conventional DNA-damaging therapies could inform personalized treatment decisions, potentially identifying patient subgroups likely to benefit from specific chemotherapy or radiation regimens .

How conserved is MORF4L1 function across different model organisms?

MORF4L1 function demonstrates remarkable evolutionary conservation across diverse model organisms, suggesting its fundamental importance in cellular processes. In mammalian systems, human MORF4L1 and mouse Mrg15 show similar functions in DNA repair and chromatin regulation, with Mrg15-deficient murine embryonic fibroblasts exhibiting sensitivity to γ-irradiation and reduced Rad51 foci formation following DNA damage. Studies in Caenorhabditis elegans reveal that mutations in the MRG15 ortholog produce phenotypes mirroring those of BRCA2 ortholog mutations, including accumulation of RPA-1 nuclear foci and aberrant chromosomal compactions in meiotic cells. This phenotypic similarity across species separated by hundreds of millions of years of evolution underscores the conserved role of MORF4L1 in maintaining genomic integrity. The protein's involvement in chromatin remodeling complexes also appears conserved, suggesting ancient evolutionary origins for its function in regulating gene expression. These cross-species consistencies enable researchers to leverage diverse model organisms to understand MORF4L1 biology, with findings in simpler systems often translating to human contexts, facilitating more comprehensive understanding of this protein's fundamental cellular roles .

What can we learn from MORF4L1 knockout models across different species?

MORF4L1 knockout models across species provide crucial insights into its biological functions and potential disease implications. In mouse models, Mrg15 deficiency results in embryonic lethality, highlighting its essential role in development. Mrg15-deficient murine embryonic fibroblasts display moderate sensitivity to γ-irradiation compared to controls, demonstrating its importance in DNA damage response. These cells also show reduced formation of Rad51 nuclear foci following DNA damage, suggesting impaired homology-directed repair. In Caenorhabditis elegans, mutants of the MRG15 ortholog exhibit phenotypes similar to BRCA2 ortholog mutants, including accumulation of RPA-1 nuclear foci and aberrant chromosomal compactions in meiotic cells. This cross-species consistency confirms MORF4L1's conserved role in maintaining genomic stability. Tissue-specific conditional knockout models have revealed MORF4L1's role in epithelial cell death in mouse pneumonia models, indicating context-dependent functions beyond DNA repair. Cell line models with MORF4L1 knockdown show enhanced proliferation, migration, and invasion capabilities in cancer contexts, further supporting its tumor suppressor function.
