HOXD12 Antibody

What is HOXD12 and what cellular functions does it regulate?

HOXD12 is a sequence-specific transcription factor belonging to the Abd-B homeobox family that plays a crucial role in developmental regulation by providing cells with specific positional identities along the anterior-posterior axis . It contains one homeobox DNA-binding domain and is primarily localized in the nucleus .

HOXD12 is part of the HOXD gene cluster located on chromosome 2, consisting of 9-11 genes arranged in tandem with other homeobox genes. This transcription factor is particularly important in embryonic development and tissue patterning . Deletions affecting the HOXD gene cluster, especially at the 5' end, have been associated with severe limb and genital abnormalities, highlighting HOXD12's developmental significance .

Recent research has also linked HOXD12 dysregulation to various pathological conditions, including cancer progression and developmental disorders, making it an important target for therapeutic research .

What types of HOXD12 antibodies are available for research and how do they differ?

Based on current research tools, there are two primary types of HOXD12 antibodies available for laboratory applications:

• Monoclonal Antibodies: These mouse-derived IgG antibodies (e.g., YP-mAb-15770) recognize specific epitopes of human and mouse HOXD12 protein. They typically target defined regions such as amino acids 191-240 of the human HOXD12 protein . Monoclonal antibodies offer high specificity and consistency between batches.

• Polyclonal Antibodies: These rabbit-derived antibodies (e.g., AP20090b) typically target the C-terminal region (amino acids 211-237) of human HOXD12. They are generated by immunizing rabbits with KLH-conjugated synthetic peptides derived from the HOXD12 sequence .

The key differences between these antibody types are summarized in the following table:

Both antibody types require proper validation for research applications to ensure specificity and reliability of experimental results .

What are the standard applications for HOXD12 antibodies in molecular biology research?

HOXD12 antibodies can be utilized in several standard molecular biology applications:

• Western Blotting (WB): Both monoclonal and polyclonal HOXD12 antibodies are validated for western blot applications, typically at dilutions of 1/500-1/2000 for monoclonal and 1/1000 for polyclonal antibodies. This technique allows researchers to detect the HOXD12 protein (observed band at approximately 28kD) in cell and tissue lysates .

• Immunohistochemistry (IHC): Monoclonal HOXD12 antibodies can be used for IHC applications at dilutions of 1/100-1/300 to visualize HOXD12 protein distribution in tissue sections .

• Immunofluorescence (IF): HOXD12 monoclonal antibodies can be employed in IF studies at dilutions of 1/50-200 to examine subcellular localization of the protein .

• ELISA: HOXD12 antibodies can be used in enzyme-linked immunosorbent assays at dilutions up to 1/20000 for high-sensitivity quantitative detection .

• Transcription Factor Activity Assays: Specialized assays can measure HOXD12 transcription factor activity in nuclear or cell lysates, providing insights into its functional status rather than mere presence .

Each application requires specific optimization protocols, including appropriate antigen retrieval methods for fixed tissues, blocking procedures to minimize non-specific binding, and validation controls to confirm antibody specificity .

How should researchers validate the specificity of HOXD12 antibodies?

Rigorous validation of HOXD12 antibodies is essential for generating reliable research data. Researchers should implement multiple validation strategies:

• Western Blot Validation: Verify that the antibody detects a band of the predicted size for HOXD12 (approximately 28kD) in relevant tissue and cell lysates. A supportive score is typically given if bands of predicted size (±20%) are detected .

• Orthogonal Validation: Compare antibody-based protein detection with RNA expression data from the same samples. High consistency between protein detection and RNA expression provides confidence in antibody specificity .

• Independent Antibody Validation: Use multiple antibodies targeting different epitopes of HOXD12 and compare staining patterns. Concordant results from independent antibodies increase confidence in specificity .

• Protein Array Analysis: Test antibody against arrays containing multiple antigens (including the target) to assess potential cross-reactivity. Depending on the interaction profile, antibodies may be scored as Supported, Approved, or Uncertain .

• Negative Controls: Include tissues or cells known not to express HOXD12 as negative controls to detect non-specific binding.

• Genetic Validation: Use cells with HOXD12 knockdown or knockout to confirm antibody specificity by demonstrating reduced or absent signal.

The Human Protein Atlas employs a systematic validation approach for antibodies, categorizing results as Enhanced, Supported, Approved, or Uncertain based on these validation methods .

How can HOXD12 antibodies be utilized to study its role in cancer progression, particularly in oligodendroglioma?

Recent research has identified HOXD12 as defining an age-related aggressive subtype of oligodendroglioma, making HOXD12 antibodies valuable tools for investigating its role in cancer:

• Expression Correlation Studies: HOXD12 antibodies can be used in IHC or western blot analyses to correlate HOXD12 protein levels with patient age, tumor grade, and survival outcomes. Studies have shown that elevated HOXD12 expression is associated with older patient age and shorter survival in oligodendroglioma patients (FDR < 0.01, FDR = 1e-5 in TCGA dataset) .

• Cellular Subpopulation Analysis: Single-cell studies have revealed that HOXD12 activity is elevated in neoplastic tissue, particularly within cycling and OPC-like cells, and is associated with a stem-like phenotype. Researchers can employ HOXD12 antibodies in combination with other markers to identify and isolate these cellular subpopulations .

• Molecular Pathway Investigation: HOXD12 expression is independently prognostic of NOTCH1 and PIK3CA mutations, loss of 15q, and MYC activation. Researchers can combine HOXD12 antibody staining with other molecular analyses to investigate these pathway interactions .

• Epigenetic Regulation Studies: HOXD12 gene body hypermethylation is associated with older age, higher WHO grade, and shorter survival. Researchers can combine antibody-based protein detection with DNA methylation analyses to investigate this regulatory mechanism .

For these advanced applications, researchers should consider:

• Using multiple antibody validation approaches to ensure specificity

  • DNA methylation analysis using specific probes (cg23130254, cg03964958, cg03371669) targeting the HOXD12 gene body

  • Protein expression analysis using validated HOXD12 antibodies

  This combined approach can help establish relationships between methylation status and protein expression levels .

• Methylation Threshold Determination: Studies have established specific thresholds for HOXD12 hypermethylation. For example, in TCGA data, a threshold of 0.3577 (mean beta value of three gene body probes) was used to classify samples as HOXD12 hypermethylated or hypomethylated .

• Cell-Type Specific Analysis: Since HOXD12 activity varies across cell types (elevated in cycling and OPC-like cells), researchers should consider cell-type specific analyses combining antibody-based detection with cell type markers .

• HOX Cluster Analysis: HOXD12 is part of a broader HOX regulatory network. Pan-HOX DNA methylation analysis has revealed an age and survival-associated HOX-high signature tightly associated with HOXD12. Researchers should consider analyzing HOXD12 in the context of other HOX genes .

• Technical Controls: When combining methylation and antibody-based studies, researchers should:

  • Include appropriate methylation controls (fully methylated and unmethylated controls)

  • Validate antibody specificity in the context of different methylation states

  • Consider how fixation methods might affect epitope accessibility in methylated vs. unmethylated states

What are the most effective protocols for using HOXD12 antibodies in transcription factor activity assays?
