plac8.1 Antibody

What is PLAC8/Plac8.1 and what are its main biological functions?

PLAC8 (Placenta-specific 8) is a protein that plays key roles in the regulation of cell proliferation and survival, with significant implications in tumorigenesis and metastasis. It functions as a critical regulator in various cellular processes, particularly those related to cancer development and progression . In cancer cells, elevated PLAC8 expression has been associated with poor prognosis and resistance to therapeutic interventions, positioning it as a potential target for cancer treatment strategies .

In developmental biology, Plac8.1 (the zebrafish ortholog) demonstrates dynamic expression patterns throughout embryogenesis. Initially expressed in a ubiquitous fashion both maternally and zygotically, by 4 days post-fertilization (dpf), Plac8.1 becomes upregulated specifically in gut tissue while being downregulated in other tissues . This shift in expression pattern suggests specialized developmental functions in gut formation and functioning. Furthermore, the intracellular distribution of Plac8.1 changes significantly during development, transitioning from predominantly cytosolic localization at gastrulation onset to becoming progressively enriched at the plasma membrane in later gastrula stages .

In immune contexts, PLAC8 has recently been identified as playing a significant role in modulating monocyte function during sepsis through the ERK signaling pathway. Research has demonstrated that PLAC8 promotes survival, proliferation, and activation of monocytes under septic conditions .

What applications are PLAC8 antibodies validated for in research?

PLAC8 antibodies have been validated for multiple research applications, with specific validation parameters depending on the antibody preparation. Based on available data, most commercial PLAC8 antibodies are validated for:

• Western Blotting/Immunoblotting: For detection and quantification of PLAC8 protein expression levels in cell and tissue lysates .

• Immunohistochemistry on Paraffin-embedded tissues (IHC-P): For visualization of PLAC8 localization within tissue sections, including tonsil, spleen, and tumor tissues .

• Immunofluorescence/Immunocytochemistry (IF/ICC): For examining subcellular localization of PLAC8 in cultured cells, including hepatocellular carcinoma cell lines .

• Enzyme-Linked Immunosorbent Assay (ELISA): For quantitative detection of PLAC8 in various sample types .

When selecting an antibody for specific applications, researchers should consider the recommended dilutions, which typically vary by application:

• ELISA: 1:2000-1:10000

• IHC: 1:20-1:200

• IF: 1:50-1:200

Validation data, including antibody specificity confirmation through immunoblotting with appropriate controls, is essential before proceeding with experimental applications .

How should researchers interpret PLAC8 expression patterns in normal versus disease states?

Interpreting PLAC8 expression patterns requires careful consideration of cellular context, tissue type, and disease state. In normal physiology, PLAC8 shows tissue-specific expression patterns with developmental regulation, as evidenced by its dynamic expression during zebrafish embryogenesis .

In pathological contexts, particularly cancer, PLAC8 expression often shows significant alterations. For example, in matched primary and metastatic colorectal cancer cell lines, higher PLAC8 levels have been observed in metastatic cells (SW620 vs. SW480 and KM12SM vs. KM12C), suggesting a potential role in metastatic progression . The strongest PLAC8 signals have been detected in microsatellite unstable mucinous cell lines like LoVo .

When analyzing PLAC8 expression in disease states, researchers should:

• Compare expression levels between normal and pathological tissues from the same origin

• Assess subcellular localization, as PLAC8 may relocalize from cytosolic to membrane-associated forms during disease progression

• Correlate expression with clinical parameters, such as tumor stage and patient outcomes

• Consider post-transcriptional regulation, as PLAC8 protein levels may not always correlate with mRNA expression

In inflammatory conditions like sepsis, PLAC8 has been shown to be highly expressed and correlated with increased levels of inflammatory cytokines (TNF-α, IL-6) and anti-inflammatory cytokines (IL-10) .

How does PLAC8 contribute to epithelial-to-mesenchymal transition (EMT) in cancer progression?

PLAC8 plays a regulatory role in the epithelial-to-mesenchymal transition (EMT), a critical process in cancer progression and metastasis. Research indicates that PLAC8 influences EMT through unconventional mechanisms that affect E-cadherin (CDH1) expression, a key epithelial marker whose repression is characteristic of EMT.

The mechanistic pathway appears to involve ERK signaling. PLAC8 has been shown to promote ERK activation, as evidenced by increased phosphorylation of ERK protein without significant changes in total ERK expression levels . This PLAC8-ERK axis likely contributes to the regulation of cellular phenotypes associated with EMT, including enhanced invasiveness and mobility.

Experimentally, researchers investigating PLAC8's role in EMT should:

• Assess changes in both mRNA and protein levels of epithelial markers (E-cadherin, ZO-1) and mesenchymal markers (N-cadherin, vimentin)

• Perform immunofluorescence to examine subcellular localization of these markers

• Evaluate ERK pathway activation through phospho-ERK analysis

• Consider cell-autonomous effects through mosaic expression studies

What methodological approaches are recommended for studying PLAC8's role in immune cell function?

Studying PLAC8's role in immune cell function, particularly in contexts like sepsis and cancer immunology, requires a multi-faceted methodological approach:
