Sox transcription factors play essential roles in a variety of critical physiological processes. Still, members of the sox gene family have not yet been genome-wide identified in shrimps. In this study, a total of five members of the sox gene family were identified from the genome of Pacific white shrimp Litopenaeus vannamei and classified into three subgroups based on the conserved HMG-box domain. Among them, three belong to the SoxB subgroup (one in B1 and two in B2), one in the SoxC subgroup, and one in the SoxE subgroup. The five sox genes had different sex-biased expression in some tissues. Sox21, soxB1, and sox14 had a higher expression in ovary than in testis. In comparison, sox4 had a male-biased specific expression in the gonad, hepatopancreas, gill, and eyestalk. There was no difference in soxE gene expression between testis and ovary. During embryonic development, the expression level of three sox genes (soxB1, sox21, and soxE) was higher in gastrulation stage compared to previous stages, declined in limb bud stage and then increased in intramembrane nauplius stage; the expression of sox4 was detected in blastula stage and continued to increase in the following two stages and then surged in intramembrane nauplius stage; the highest expression of sox14 was in the fertilized egg stage, and the expression level decreased with the development of the embryo. These results suggest that the shrimp sox gene family may be involved in gametogenesis, tridermogenesis, and neurogenesis.

Objectives: To investigate the effects of suberoylanilide hydroxamic acid (SAHA) on lung fibroblast activation and to examine the role of p66Shc in this process.
Methods: An in vitro pulmonary fibrosis model was established using transforming growth factor-β (TGF-β)-induced MRC-5 lung fibroblasts. The proliferation and migration capacities of MRC-5 cells, along with the expression of fibrosis-related genes, were assessed following treatment with SAHA and/or silence of p66Shc.

Understanding the role of metabolic processes during inner ear development is essential for identifying targets for hair cell (HC) regeneration, as metabolic choices play a crucial role in cell proliferation and differentiation. Among the metabolic processes, growing evidence shows that glucose metabolism is closely related to organ development. However, the role of glucose metabolism in mammalian inner ear development and HC regeneration remains unclear.

Oligodendroglial cells generate myelin sheaths in the vertebrate central nervous system to render rapid saltatory conduction possible and express the highly related Sox8, Sox9 and Sox10 transcription factors. While Sox9 and Sox10 fulfill crucial regulatory roles, Sox8 has only a limited impact on oligodendroglial development and myelination. By replacing Sox10 with Sox8 or Sox9 in the oligodendroglial Oln93 cell line, and comparing the expression profiles, we show here that Sox8 regulates the same processes as Sox10 and Sox9, but exhibits a substantially lower transcriptional activity under standard culture conditions.

Sox genes encode a family of transcription factors that regulate multiple biological processes during metazoan development, including embryogenesis, tissue homeostasis, nervous system specification, and stem cell maintenance. The planarian Dugesia japonica contains a reservoir of stem cells that grow and divide continuously to support cellular turnover. However, whether SOX proteins retain these conserved functions in planarians remains to be determined.
