Recombinant Human Spermatogenesis-associated protein 12 (SPATA12)

What is the primary function of SPATA12 in human cells?

SPATA12 (Spermatogenesis-associated protein 12) primarily functions as an inhibitor in both spermatogenesis and tumorigenesis. Research has demonstrated that SPATA12 plays a significant role in maintaining genomic integrity. It responds to cellular stress conditions, particularly oxidative damage and UV-mediated DNA damage, suggesting its importance in cellular protective mechanisms .

The protein's inhibitory function in spermatogenesis indicates its role as a regulatory factor in male reproductive development, while its inhibitory effect in tumorigenesis suggests potential tumor suppressor activity that warrants further investigation in cancer research contexts .

How is SPATA12 expression regulated in cellular stress conditions?

SPATA12 expression is upregulated in response to oxidative stress, particularly through a transcription factor activator protein-1 (AP-1) mediated pathway. Studies have established cellular models of oxidative stress using H₂O₂ treatment and demonstrated that:

• H₂O₂ significantly upregulates SPATA12 expression in a dose-dependent manner

• The AP-1 binding site within the SPATA12 core promoter (77-302 bp) is critical for this response

• The binding site encompasses the sequence 5′-TGAGTCA-3′, a core sequence in the AP-1 motif also known as the TPA responsive element (TRE)

Through luciferase reporter gene assays, researchers have confirmed that the TRE element within the SPATA12 promoter is crucial for responding to H₂O₂ treatment. When this element is mutated or deleted, the relative luciferase activity of the promoter is significantly reduced in cells exposed to H₂O₂, indicating that AP-1 is directly involved in the H₂O₂-induced transcriptional upregulation of SPATA12 .

Additionally, SPATA12 expression can be induced by UV-C radiation, with its promoter activity being upregulated in response to UV-C exposure through similar AP-1 mediated mechanisms .

What cellular localization patterns does SPATA12 exhibit?

SPATA12 primarily exhibits nuclear localization patterns, particularly when interacting with its binding partner CHD2 (chromodomain helicase DNA binding protein 2). This localization has been confirmed through:

• Bimolecular fluorescence complementation (BiFC) assays

• Subcellular co-localization experiments using confocal microscopy

• Fluorescence microscopy studies with tagged proteins

These techniques have demonstrated that SPATA12 and CHD2 interact in the nucleus, suggesting that SPATA12's function may be closely related to nuclear processes such as transcription regulation and DNA damage response mechanisms .

What are the most effective methods for studying SPATA12-protein interactions?

Multiple complementary techniques have proven effective for investigating SPATA12 protein interactions:

Yeast Two-Hybrid Screening System:
This powerful genetic strategy successfully identified CHD2 as an interacting partner of SPATA12. The methodology involves:

• Generating a bait construct by amplifying the SPATA12 open reading frame and inserting it into the pGBKT7 vector

• Transforming the bait plasmid into yeast strain AH109

• Screening a human testis cDNA library in the pGADT7-Rec vector

• Identifying positive colonies through their ability to grow on selective media and verification by β-galactosidase assays

Bimolecular Fluorescence Complementation (BiFC):
This technique visualizes protein interactions in living cells by:

• Creating fusion constructs of SPATA12 and potential interacting proteins with complementary fragments of a fluorescent protein

• Transfecting cells with both constructs

• Observing fluorescence reconstitution when the proteins interact

• Analyzing using laser scanning confocal microscopy

Subcellular Co-localization:
Verification of protein interactions through:

• Creating fluorescent protein-tagged constructs (e.g., pEGFP-SPATA12 and pDsRed-CHD2)

• Co-transfecting cells with both constructs

• Visualizing the localization patterns using confocal microscopy

• Analyzing overlap in subcellular distribution

These methods have collectively established that SPATA12 interacts with CHD2 in the nucleus, providing insights into its potential role in transcriptional regulation and DNA damage response pathways .

What cellular models are most appropriate for studying SPATA12 function in oxidative stress?

Based on published research, the following cellular models have proven effective for studying SPATA12 function in oxidative stress:

HeLa and MCF-7 Cell Lines:
These established human cancer cell lines have been successfully used to:

• Create oxidative stress models using H₂O₂ treatment

• Transfect with SPATA12 expression vectors

• Evaluate the effects of SPATA12 on oxidative stress parameters

Oxidative Stress Parameters to Evaluate:
When establishing these models, researchers typically assess:

Induction Protocol:
For H₂O₂-induced oxidative stress, researchers typically:

• Treat cells with varying concentrations of H₂O₂ (typically 20-100 μM)

• Incubate for defined periods (typically 12-24 hours)

• Verify oxidative stress induction by measuring decreased SOD activity, decreased GSH levels, and increased MDA levels

This model is particularly valuable because it allows direct observation of SPATA12's protective effects against oxidative damage through its ability to reduce ROS and MDA levels, even without altering SOD activity or GSH content .

How can researchers effectively measure SPATA12's impact on cellular response to DNA damage?

Several experimental approaches have been validated for measuring SPATA12's impact on cellular response to DNA damage:

Colony Formation Assay:
This technique assesses the effects of SPATA12 on cell proliferation and survival following DNA damage by:

• Transfecting cells with SPATA12 expression vectors

• Exposing cells to UV-C radiation or other DNA damaging agents

• Allowing colonies to form over 1-2 weeks

• Quantifying and comparing colony numbers and sizes between SPATA12-expressing and control cells

Host Cell Reactivation Assay:
This approach evaluates the influence of SPATA12 on DNA repair capacity by:

• Damaging a reporter plasmid (typically containing luciferase gene) with UV-C radiation

• Co-transfecting cells with the damaged reporter and SPATA12 expression vectors

• Measuring reporter gene activity after allowing cells time for repair

• Comparing repair efficiency between SPATA12-expressing and control cells

Flow Cytometry Analysis:
Flow cytometry provides insights into SPATA12's effects on cell cycle progression and apoptosis by:

• Transfecting cells (H1299, MCF-7, HeLa) with SPATA12

• Exposing cells to DNA damage

• Staining with appropriate markers (e.g., Annexin V/PI for apoptosis)

• Analyzing cell cycle distribution and apoptotic fractions

• Comparing results between wild-type and p53-deficient cells to understand p53 dependency

Hoechst Staining:
This technique visualizes nuclear morphology to assess apoptosis by:

• Treating cells with DNA damaging agents (e.g., 70 μM H₂O₂)

• Staining with Hoechst dye

• Observing chromatin condensation as an indicator of apoptosis

• Comparing results between SPATA12-expressing and control cells

Research has shown that SPATA12 expression inhibits H₂O₂-induced apoptosis, as evidenced by decreased chromatin condensation in the superposition field of view following SPATA12 gene transfection . Additionally, colony formation assays demonstrate that SPATA12 leads to inhibition of cellular proliferation following UV-C-irradiated DNA damage .

How does SPATA12 interact with the DNA damage response pathway?

SPATA12 intersects with the DNA damage response pathway through several key mechanisms:

Interaction with CHD2:
SPATA12 directly interacts with CHD2 (chromodomain helicase DNA binding protein 2), which has been established through:

• Yeast two-hybrid screening

• Bimolecular fluorescence complementation

• Subcellular co-localization assays

This interaction is particularly significant because CHD2 is a chromatin-remodeling factor required for genomic stability maintenance and is involved in the later stage of the DNA damage response pathway by influencing p53 transcriptional activity .

p53 Pathway Connection:
SPATA12 demonstrates a biological association with p53 in UV-C-irradiated DNA damage, as evidenced by:

• Flow cytometry results showing differential effects in p53-positive vs. p53-negative cell lines

• Investigations showing SPATA12 can upregulate p53 expression

The p53 connection is crucial, as p53 is a central coordinator of the cellular response to DNA damage, regulating cell cycle arrest, DNA repair, and apoptosis.

AP-1 Mediated Induction:
During DNA damage processes:

• AP-1 is activated through phosphorylation pathways, primarily via c-Jun N-terminal kinase (JNK)

• Activated AP-1 binds to the SPATA12 promoter region

• This binding increases SPATA12 transcription

• Elevated SPATA12 levels then contribute to cellular responses to DNA damage

The AP-1 binding site within the SPATA12 core promoter is critical for this response pathway, forming a regulatory axis connecting cellular stress, AP-1 activation, SPATA12 upregulation, and subsequent protective responses .

What is the relationship between SPATA12 and reactive oxygen species (ROS) in cellular damage?

SPATA12 exhibits a complex relationship with reactive oxygen species (ROS) that positions it as a key antioxidant factor:

Antioxidant Function:
Experimental evidence demonstrates SPATA12's antioxidant properties through:

• Reduction of intracellular ROS levels as measured by DCFH-DA oxidation

• Significant decrease in malondialdehyde (MDA) content, a marker of lipid peroxidation

• Inhibition of H₂O₂-induced apoptosis

The relationship is bidirectional:

• ROS (specifically H₂O₂) induces SPATA12 expression

• SPATA12, once expressed, reduces ROS levels

Selective Antioxidant Mechanisms:
Interestingly, SPATA12 exhibits selective effects on oxidative parameters:

This selective pattern suggests that SPATA12 functions as an antioxidant not by enhancing conventional antioxidant systems (SOD, GSH) but through direct or indirect mechanisms that reduce ROS generation or enhance ROS neutralization through alternative pathways .

ROS-Mediated Signaling:
Beyond direct antioxidant effects, SPATA12 appears integrated in ROS-mediated signaling:

• ROS activates JNK in cells

• Activated JNK phosphorylates c-Jun and c-Fos proteins

• This induces AP-1 transcriptional activity

• AP-1 binds to the SPATA12 promoter, increasing its expression

• Elevated SPATA12 then reduces ROS levels, potentially creating a negative feedback loop

This relationship positions SPATA12 as a potential therapeutic target for conditions characterized by oxidative stress and suggests its relevance in diverse pathological contexts beyond reproductive biology .

What are the contradictory findings in SPATA12 research and how can they be reconciled?

Several contradictory or seemingly paradoxical findings exist in SPATA12 research that require careful analysis:

Contradictory Finding 1: Inhibitory vs. Protective Roles
SPATA12 is described as an "inhibitor" in spermatogenesis and tumorigenesis, yet plays a "protective" role against oxidative damage and apoptosis.

Reconciliation: These findings can be reconciled by understanding SPATA12 as a context-dependent regulator. Its inhibitory effects on proliferation and development likely represent protective mechanisms against genomic instability. The seemingly contradictory functions actually serve the unified purpose of maintaining cellular integrity under different conditions.

Contradictory Finding 2: Promoter Activity Variations
Research shows inconsistent activity patterns of the SPATA12 promoter regions:

Reconciliation: Researchers hypothesize "that there may be a negative regulatory element located at the −946 to 90 bp region that may affect the transcriptional activity of the SPATA12 promoter" . This suggests a complex regulatory mechanism with multiple control elements that respond differently to cellular conditions.

Contradictory Finding 3: Relationship with p53
The relationship between SPATA12 and p53 shows some paradoxical elements:

Reconciliation: These contradictions highlight knowledge gaps rather than true contradictions. Future research should focus on the precise mechanisms by which SPATA12 influences p53 activity, potentially through its interaction with CHD2 or through independent pathways.

To address these contradictions, researchers should consider:

• Conducting studies with tissue-specific or conditional SPATA12 knockout/knockin models

• Performing detailed time-course analyses to understand temporal aspects of SPATA12 function

• Utilizing proteomics approaches to identify the complete interactome of SPATA12

• Employing ChIP-seq to identify all genomic regions affected by SPATA12 activity

How can resveratrol be utilized in SPATA12 research?

Resveratrol presents a valuable tool for SPATA12 research, offering a non-toxic approach to modulate SPATA12 expression:

Mechanism of Action:
Resveratrol enhances SPATA12 expression through:

• Activation of AP-1 (activator protein-1)

• Increased binding of AP-1 to the TRE element within the SPATA12 promoter

• Upregulation of SPATA12 mRNA transcription

Experimental Applications:
Researchers can employ resveratrol in SPATA12 studies through several approaches:

Advantages as a Research Tool:

• Non-toxic activation: At 20 μM concentration, resveratrol shows no cytotoxicity while effectively increasing SPATA12 expression

• Specificity: Works through the AP-1 pathway, providing a targeted approach

• Accessibility: Widely available and well-characterized compound

• Translational potential: Natural compound with established biological effects

Research Design Considerations:
When incorporating resveratrol in SPATA12 research:

• Verify cytotoxicity profiles using MTT assays for each cell line

• Establish dose-response curves (research indicates 20 μM for 12h as effective)

• Include appropriate controls (AP-1 inhibitors, promoter constructs with mutated AP-1 sites)

• Consider potential pleiotropic effects of resveratrol when interpreting results

This approach offers a valuable alternative to genetic overexpression, allowing for inducible and potentially reversible modulation of SPATA12 levels in experimental systems.

How can SPATA12 research contribute to understanding contradictions in genomic data?
