Therapeutic potential of SOX family transcription factors in osteoarthritis by Yue Huang, Zhuo Wang

“…While SOX9 has been utilized as a biomarker to indicate the occurrence and prognosis of osteoarthritis, investigations into other members of the SOX family and the development of targeted treatments around SOX9 are still required.Purpose This article considers the impact of the SOX protein on the development and inhibition of osteoarthritis and highlights the need for therapeutic approaches targeting SOX9, as supported by existing research.Results SOX9 can contribute to the process of osteoarthritis through acetylation and ubiquitination modifications. The regulation of the WNT signalling pathway, Nrf2/ARE signalling pathway, NF-κB signalling pathway and SOX9 is implicated in the emergence of osteoarthritis. …”

Role of Epigenetics in Modulating Phenotypic Plasticity against Abiotic Stresses in Plants by Fayaz Ahmad Dar, Naveed Ul Mushtaq, Seerat Saleem, Reiaz Ul Rehman, Tanvir Ul Hassan Dar, Khalid Rehman Hakeem

“…Epigenomics refers to the large-scale study of epigenetic marks on the genome, which include covalent modifications of histone tails (acetylation, methylation, phosphorylation, ubiquitination, and the small RNA machinery). Studies based on epigenetics have evolved over the years especially in understanding the mechanisms at transcriptional and posttranscriptional levels in plants against various environmental stimuli. …”

Endogenous peptide CBDP1 inhibits clear cell renal cell carcinoma progression by targeting USP5/YTHDF2/TRPM5 axis by Yang Zhang, Wei Zhu, Ruijie Tao, Weijian Li, Chunming Jiang, Xiang Yan

“…Through mechanistic investigations, it was revealed that CBDP1 facilitates the interaction between YTHDF2 and the deubiquitinase USP5, thereby impeding the ubiquitination and degradation of YTHDF2. The upregulated YTHDF2 then binds to TRPM3 mRNA and promotes its degradation, ultimately reducing TRPM3 expression levels. …”
