Advanced Research Questions

How to resolve discrepancies in PMDH1 detection between Western blot and IHC?

• Methodology:

  • Variable Analysis: Compare fixation methods (e.g., paraformaldehyde vs. methanol) and antigen retrieval techniques (e.g., heat-induced vs. enzymatic) .

  • Quantitative Correlation: Use densitometry (Western blot) vs. pixel intensity (IHC) to quantify expression levels.

What statistical approaches address PMDH1 expression variability in heterogeneous tumor samples?

• Methodology:

  • Stratify samples by histopathological subtype.

  • Apply mixed-effects models to account for intra-tumor heterogeneity.

  • Use spatial transcriptomics to correlate PMDH1 levels with microenvironmental factors.

How to design a CRISPR screen to identify PMDH1 functional interactors?

• Methodology:

  • Use a genome-wide sgRNA library in PMDH1-KO cell lines.

  • Apply enrichment analysis (e.g., MAGeCK) to identify pathways with synthetic lethality.

  • Validate hits via co-immunoprecipitation (Co-IP) and rescue experiments.

Data Contradiction Analysis

How to interpret conflicting PMDH1 localization data across studies?

• Methodology:

  • Meta-analysis: Compare cell lines, fixation protocols, and antibody clones used in conflicting studies.

  • Subcellular fractionation: Isolate cytoplasmic/nuclear proteins to confirm localization.

What orthogonal assays confirm PMDH1 antibody specificity in flow cytometry?

• Methodology:

  • Compare staining patterns with siRNA-mediated knockdown.

  • Use fluorescence-minus-one (FMO) controls to gate true-positive populations.

  • Validate with mass spectrometry of immunoprecipitated proteins.
