Comparative Transcriptomic Analysis of Male and Female Gonads in Hemibagrus guttatus (Lacepède). (PubMed, Animals (Basel))
From the DEG set, we further highlighted five genes with pronounced sex-biased expression: rbm46 (RNA Binding Motif Protein 46) exhibited gonad-specific expression, whereas myc (v-myc avian myelocytomatosis viral oncogene homolog), angptl4 (Angiopoietin-Like 4), sox9 (SRY-Related HMG-Box Gene 9), and fzd2 (Frizzled Class Receptor 2) showed marked expression differences between male and female gonads. These findings provide insights into the molecular mechanisms underlying sex differentiation in H. guttatus, offer potential molecular markers for sex identification, and establish a scientific basis for germplasm conservation and the optimization of breeding techniques.
