PC3/Tis21 is a transcriptional cofactor that inhibits proliferation in several cell types, including neural progenitors. Here, we report that PC3/Tis21 associates with HDAC1, HDAC4, and HDAC9 in vivo, in fibroblast cells. Furthermore, when HDAC1, HDAC4, or HDAC9 are silenced in fibroblasts or in a line of cerebellar progenitor cells, the ability of PC3/Tis21 to inhibit proliferation is significantly reduced. Overexpression of HDAC1, HDAC4, or HDAC9 in fibroblasts and in cerebellar precursor… 
Interfering histone deacetylase 4 inhibits the proliferation of vascular smooth muscle cells via regulating MEG3/miR-125a-5p/IRF1
TLDR
Results suggested that HDAC4 interference inhibited PDGF-BB-induced VSMCs proliferation via regulating MEG3/miR-125a-5p/IRF1 axis, and then alleviated IH.
The downregulation of putative anticancer target BORIS/CTCFL in an addicted myeloid cancer cell line modulates the expression of multiple protein coding and ncRNA genes
The BORIS/CTCFL gene, is a testis-specific CTCF paralog frequently erroneously activated in cancer, although its exact role in cancer remains unclear. BORIS is both a transcription factor and an
Tumor suppressors BTG1 and BTG2: Beyond growth control
TLDR
The molecular mechanisms and biological consequences of BTG1 and BTG2 deregulation during cancer progression are highlighted and the potential clinical implications of these findings are elaborate.
Functional Genomics Identifies Tis21-Dependent Mechanisms and Putative Cancer Drug Targets Underlying Medulloblastoma Shh-Type Development
TLDR
The role of Tis21 is defined in the regulation of gene expression, through epigenetic and RNA processing mechanisms, influencing the fate of the GCPs, in a novel medulloblastoma mouse model.
Clinical significance of HDAC1, -2 and -3 expression levels in esophageal squamous cell carcinoma
TLDR
HDR1 expression may be used as a risk factor for ESCC and HDAC2 levels may be use to predict invasion depth, and the expression of HDAC1, -2 and -3 has ethnic differences.
The posttranslational modification of HDAC4 in cell biology: Mechanisms and potential targets
TLDR
This review focuses on the posttranslational modification of HDAC4 in cell biology, providing an important target for future disease treatment.
Genetic Interaction-Based Biomarkers Identification for Drug Resistance and Sensitivity in Cancer Cells
Btg2 mutation induces renal injury and impairs blood pressure control in female rats.
TLDR
The Btg2 mutated rats exhibited impaired BP and proteinuria responses to a high salt diet compared to wild type rats, and several potential upstream targets that can be explored to further isolate therapeutic approaches for SS HTN were identified.

Essential function of histone deacetylase 1 in proliferation control and CDK inhibitor repression
TLDR
This study provides the first evidence that a histone deacetylase is essential for unrestricted cell proliferation by repressing the expression of selective cell cycle inhibitors.
HDAC4 promotes growth of colon cancer cells via repression of p21.
TLDR
It is demonstrated that HDAC4 is expressed in the proliferative zone in small intestine and colon and that its expression is down-regulated during intestinal differentiation in vivo and in vitro.
HDAC4 inhibits cell‐cycle progression and protects neurons from cell death
TLDR
It is shown that forced expression of HDAC4 in cerebellar granule neurons protects them against low potassium‐induced apoptosis and also protects HT22 neuroblastoma cells from death induced by oxidative stress.
Class II histone deacetylases: structure, function, and regulation.
TLDR
Intriguingly,HDAC4, HDAC5, and probably HDAC7 are regulated through subcellular compartmentalization controlled by site-specific phosphorylation and binding of 14-3-3 proteins; the regulation of these HDACs is thus directly linked to cellular signaling networks.
Arrest of G1-S Progression by the p53-Inducible Gene PC3 Is Rb Dependent and Relies on the Inhibition of Cyclin D1 Transcription
TLDR
It is reported that expression of PC3 in cycling cells induced accumulation of hypophosphorylated, growth-inhibitory forms of pRb and led to G1 arrest, and that PC3 acts, either directly or indirectly, as a transcriptional regulator of cyclin D1.
The Histone Deacetylase 9 Gene Encodes Multiple Protein Isoforms*
TLDR
The results suggest that HDAC9 plays a role in hematopoiesis; its deregulated expression may be associated with some human cancers.
PC4/Tis7/IFRD1 Stimulates Skeletal Muscle Regeneration and Is Involved in Myoblast Differentiation as a Regulator of MyoD and NF-κB*
TLDR
The results indicate that PC4 plays a role in muscle differentiation by controlling the MyoD pathway through multiple mechanisms, and as such, it positively regulates regenerative myogenesis.
Dual Control of Neurogenesis by PC3 through Cell Cycle Inhibition and Induction of Math1
TLDR
The data suggest that cell cycle exit of Cerebellar granule cell precursors and the onset of cerebellar neurogenesis are coordinated by PC3 through transcriptional control of cyclin D1 and Math1, respectively.
Differential localization of HDAC4 orchestrates muscle differentiation.
TLDR
It is shown that HDAC4 is cytoplasmic during myoblast differentiation, but relocates to the nucleus once fusion has occurred, establishing a role for HDAC2 in muscle differentiation and phosphorylation-dependent binding to 14-3-3 proteins in a phosphorylated manner.
Nerve Growth Factor Induces Transcription of the p21 WAF1/CIP1 and Cyclin D1 Genes in PC12 Cells by Activating the Sp1 Transcription Factor
TLDR
It is shown that induction is at the level of transcription and that the DNA elements in both promoters that are required for NGF-specific induction are clusters of binding sites for the Sp1 transcription factor.
