Histone deacetylase 4 (HDAC4) mRNA and Forkhead box S1 (FOXS1) mRNA (HDAC4 mRNA / FOXS1 mRNA)

Histone deacetylase 4 (HDAC4) and Forkhead box S1 (FOXS1) are two distinct genes whose messenger RNAs (mRNAs) are frequently co-targeted and co-regulated in various physiological and pathological contexts, particularly in muscle development and cancer. HDAC4 is a Class IIa histone deacetylase that plays a critical role in gene silencing and muscle atrophy by regulating the acetylation of histones and other transcription factors. FOXS1 is a transcription factor involved in cell differentiation, proliferation, and epithelial-mesenchymal transition (EMT), particularly in the liver and nervous system. Both mRNAs are validated or putative targets of the muscle-specific microRNAs miR-206 and miR-1 (myomiRs), which suppress their expression to promote myogenic differentiation and maintain muscle homeostasis. In diseases such as chondrosarcoma, liver fibrosis, and muscle wasting, the dysregulation of the HDAC4/FOXS1 axis is often linked to aberrant TGF-beta signaling and tumor progression. Therapeutic strategies targeting these mRNAs include miRNA mimics (e.g., miR-206 mimics) and small molecules like DZNep or pirfenidone, which modulate their expression to restore normal cellular function or inhibit tumor growth.
