Summary
Histone deacetylases (HDACs) impact cancer. HDAC2 promotes cancer stemness and suppresses immunity, while HDAC7 inhibits stemness and enhances anti-tumor immune responses in solid tumors.
Area of Science:
- Oncology
- Molecular Biology
- Immunology
Background:
- Histone deacetylases (HDACs) are implicated in cancer development.
- Understanding HDAC family roles in cancer stemness and immunity is crucial.
Purpose of the Study:
- To comprehensively analyze associations between HDACs and cancer traits.
- To investigate the link between HDACs, cancer stemness, and tumor immunity.
Main Methods:
- Utilized TCGA data and bioinformatic tools (GEPIA2, TISIDB, GSCA, Enrichr, GSEA).
- Analyzed transcriptomic profiles for correlations with clinicopathological and molecular features.
Main Results:
- Class I HDACs (e.g., HDAC2) correlate with increased cancer stemness.
- Class IIA HDACs (e.g., HDAC7) correlate with decreased cancer stemness.
- HDAC2 overexpression is linked to immunosuppressive tumor microenvironments.
- HDAC7 upregulation is associated with enhanced anti-tumor immunity and T cell infiltration.
Conclusions:
- Specific HDAC members differentially regulate cancer stemness and immune evasion.
- HDAC2 and HDAC7 represent distinct molecular players in solid tumor progression and immune modulation.

01:37Epigenetic Regulation
3.0K
Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

02:30Histone Variants at the Centromere
4.3K
Histone variants are the histone proteins with structural and sequence variations. These variants may be regarded as “mutant” forms that replace their canonical histone counterparts in the nucleosomes. Specific post-translational modifications on the histone variants enable further chromatin complexity and regulate tissue-specific gene expression. The most common histone variants are from histone H2A, H2B, and linker histone H1 families. However, several variants of histone H3...

01:06Induced Pluripotent Stem Cells
4.0K
Stem cells are undifferentiated cells that divide and produce different cell types. Ordinarily, cells that have differentiated into a specific cell type are terminally differentiated; however, scientists have found a way to reprogram these mature cells so that they dedifferentiate and return to an unspecialized, proliferative state. These cells are pluripotent like embryonic stem cells—able to produce all cell types—and are called induced pluripotent stem cells (iPSCs).

1.6K
Chromatin modification alters gene expression; therefore, scientists can add histone-modifying enzymes, histone variants, and chromatin remodeling complexes to somatic cells to aid reprogramming into pluripotent stem (iPS) cells.
Compact chromatin makes reprogramming difficult. Enzymes, such as histone demethylases and acetyltransferases, are often added during reprogramming to loosen the chromatin, making the DNA more accessible to transcription factors. Molecules that inhibit histone...

4.9K
Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often causing tumor recurrence. These cancer stem cells possess the potential for self-renewal and multi-lineage differentiation and are often responsible for the therapeutic resistance displayed in most cancers.

02:25Spreading of Chromatin Modifications
8.2K
The histone proteins in the nucleosomes are post-translationally modified (PTM) to increase or decrease access to DNA. The commonly observed PTMs are methylation, acetylation, phosphorylation, and ubiquitination of lysine amino acids in the histone H3 tail region. These histone modifications have specific meaning for the cell. Hence, they are called "histone code". The protein complex involved in histone modification is termed as "reader-writer" complex.
