MROH8 Antibody

What is MROH8 and what is known about its biological function?

MROH8 (Maestro Heat-like Repeat-containing Protein Family Member 8) is a protein encoded by the MROH8 gene located on chromosome 20. It is also known by several alternative names including C20orf131, C20orf132, dJ621N11.3, and dJ621N11.4 .

Recent research in pancreatic cancer has identified MROH8 as part of a regulatory pathway involving N6-methyladenosine (m6A) RNA modifications. MROH8 appears to function by modulating transcription factor activity, particularly through interaction with TATA-binding protein (TBP). Specifically, MROH8 has been shown to:

• Negatively regulate TBP by promoting its degradation after binding

• Function downstream of the m6A writer METTL16

• Correlate with improved survival in pancreatic cancer patients

• Inhibit tumor cell growth when overexpressed

This emerging evidence suggests MROH8 may act as a tumor suppressor through transcriptional regulation mechanisms, though more research is needed to fully elucidate its functions across different tissues and cellular contexts.

What types of MROH8 antibodies are available for research applications?

Most commercially available MROH8 antibodies are polyclonal, derived primarily from rabbits, with different epitope targets allowing researchers to select antibodies appropriate for their specific experimental needs .

What validation methods should I use to confirm MROH8 antibody specificity?

Proper validation of MROH8 antibodies is critical for ensuring experimental reliability. A comprehensive validation strategy should include:

• Western blot molecular weight verification:

  • Confirm detection at the expected molecular weight for MROH8

  • Some antibodies detect bands of approximately 140-150 kDa, consistent with predicted MROH8 size

• Positive and negative controls:

  • Use cell lines with known MROH8 expression levels

  • Implement MROH8 knockdown/knockout samples as negative controls

  • Research shows that MROH8 knockdown increases cell colony formation while overexpression inhibits tumor cell growth

• Peptide competition assays:

  • Pre-incubate antibody with the immunizing peptide (when available)

  • For example, peptide sequences like "PHLENLDTIIKLPLRFQRLGHLVALMALLCGDPQEKVAEEAAEGIHSLLH" for NBP157772

• Protein array testing:

  • Some manufacturers verify specificity on protein arrays containing target protein plus hundreds of non-specific proteins

• Cross-application validation:

  • Confirm consistency across multiple applications (e.g., WB, IHC, IF)

  • Document optimal dilutions for each application (e.g., 1:500-1:1000 for IHC )

• Correlation with mRNA expression data:

  • Compare protein detection with transcriptomic data

  • MROH8 mRNA stability has been shown to be enhanced by m6A modifications mediated by METTL16

Always document validation procedures thoroughly and include appropriate controls in all experiments to ensure reliable interpretation of results.

How should I design experiments to study MROH8's role in transcriptional regulation?

MROH8 has been identified as a regulator of transcription factor activity, particularly through its interaction with TBP. To investigate this function:

• Protein-protein interaction studies:

  • Co-immunoprecipitation (Co-IP): Use MROH8 antibodies to pull down protein complexes and probe for transcription factors like TBP

  • Reciprocal Co-IP: Use TBP antibodies to confirm interaction from both directions

  • Research has demonstrated that MROH8 physically binds to TBP protein

• Protein degradation analysis:

  • Cycloheximide chase assays: Monitor TBP degradation rates with/without MROH8 overexpression

  • Proteasome inhibitor studies: Determine if MROH8-mediated TBP degradation is proteasome-dependent

  • Temporal analysis: In published studies, inducing MROH8 overexpression and then withdrawing the inducer showed that decreasing MROH8 levels led to increasing TBP levels

• Transcriptional impact assessment:

  • Luciferase reporter assays: Measure transcriptional activity of TBP-dependent promoters

  • ChIP-seq analysis: Assess genome-wide changes in TBP binding with MROH8 modulation

  • RNA-seq: Identify genes differentially expressed with MROH8 manipulation

• Domain mapping experiments:

  • Generate MROH8 truncation mutants to identify regions critical for TBP interaction

  • Use antibodies targeting different MROH8 domains to potentially disrupt specific interactions

• Functional validation:

  • MROH8 knockdown and overexpression studies in relevant cell lines

  • Rescue experiments with wild-type vs. interaction-deficient MROH8 mutants

  • Published data shows MROH8 knockdown promotes cell colony formation while overexpression inhibits tumor cell growth

A comprehensive experimental design should incorporate multiple methodological approaches to provide robust evidence for MROH8's transcriptional regulatory functions.

What experimental strategies can optimize detection of MROH8 in clinical samples with low expression?

Detecting low-abundance proteins like MROH8 in clinical samples requires specialized approaches:

• Signal amplification methods:

  • Polymer-based detection systems: Often provide better signal-to-noise ratio than ABC methods

  • Higher-sensitivity substrates: Super Signal or femto-level chemiluminescent reagents for Western blotting

• Sample preparation optimization:

  Procedure	Standard Method	Enhanced Method for Low Expression
  Antigen retrieval	Citrate buffer pH 6.0	Test multiple buffers (citrate pH 6.0, EDTA pH 8.0, Tris-EDTA pH 9.0)
  Antibody incubation	1 hour at RT	Overnight at 4°C with optimized concentration
  Blocking	Standard BSA or serum	Specialized blockers to reduce background
  Signal detection	Standard DAB	Amplified detection systems (TSA, QD)

• Antibody selection and optimization:

  • Choose antibodies validated for high sensitivity (e.g., those confirmed for detecting endogenous levels)

  • Perform careful titration experiments to determine optimal concentration

  • For IHC/IF: 1:500-1:1000 dilutions are typically recommended

  • For Western blot: 1:1000-2000 or 1.0 μg/ml concentrations are often optimal

• Pre-enrichment strategies:

  • RNAscope for mRNA detection to complement protein analysis

  • Multiplexed detection to visualize MROH8 alongside known interacting partners

These strategies can significantly improve detection sensitivity for MROH8 in clinical samples, enabling more reliable analysis in experimental and diagnostic contexts.

How does MROH8 interact with the m6A modification pathway in cancer cells?

Recent research has revealed a novel regulatory axis involving MROH8 and m6A RNA modifications in pancreatic cancer:

• METTL16-MROH8-TBP-CAPN2 regulatory axis:

  • METTL16 and YTHDC2 (an m6A reader) collaboratively enhance MROH8 mRNA stability

  • MROH8 negatively correlates with CAPN2 (r=-0.3, P<0.001)

  • MROH8 positively correlates with better survival outcomes in pancreatic cancer patients

• Methodological approach to study this pathway:

  • m6A-specific quantitative PCR to measure modification levels

  • RNA immunoprecipitation using m6A antibodies followed by MROH8 detection

  • Co-IP experiments between MROH8 and transcription factors

  • Functional assays measuring tumor proliferation and metastasis with pathway manipulation

• Experimental design considerations:
