Using the primers from SRY gene--HMG Box for PCR amplification in genomic DNA of Muntiacus reevesi cell strains, a 220bp fragment was obtained in the male but not in the female. The 220bp fragment was cloned into the pGEM-T vector using T/A clone method. The identified positive clone was sequenced. The result shows that 82.6% nucleotides(152bp/184bp) are homologous between Muntiacus Sry and human SRY gene. It suggests that SRY is highly conserved during evolution.

In mammals, male sexual development is initiated by the expression of the Sex-determining-Region-Y (SRY) gene. SRY contains a highly conserved High Mobility Group (HMG) box essential for DNA binding and activity. Variants in SRY cause Differences of Sex Development (DSD), accounting for 10-15% of 46,XY gonadal dysgenesis cases.

Ovarian agenesis (OA) is a rare congenital condition characterized by the absence of one or both ovaries, often associated with chromosomal abnormalities, hormonal imbalances, and structural deformities. The condition is frequently diagnosed in females presenting with primary amenorrhea and delayed sexual development. This case report highlights a unique presentation of bilateral ovarian agenesis in a patient with chromosome X translocation, bone modeling disease, and primary amenorrhea.

is an ancestral homologous gene of the male-determining in eutherian mammals and determines maleness in medaka fish. In the Japanese frog, , is located on the Z and W chromosomes. To assess the sex-determining function of in this frog, we investigated its expression in gonads during early tadpole development and conducted genome-editing experiments.

Expression of SRY-box transcription factor 17 (Sox17) in the endodermal region caudal to the hepatic diverticulum during late gastrulation is necessary for hepato-pancreato-biliary system formation. Analysis of an allelic series of promoter-proximal mutations near the transcription start site (TSS) 2 of Sox17 has revealed that gallbladder (GB) and extrahepatic bile duct (EHBD) development is exquisitely sensitive to Sox17 expression levels. Deletion of a SOX17-binding cis-regulatory element in the TSS2 promoter impairs GB&EHBD development by reducing outgrowth of the nascent biliary bud.

Squamous cell carcinomas (SCC) are often preceded by potentially malignant precursor lesions, most of which remain benign. The terminal exhaustion phenotypes of effector T-cells and the accumulation of myeloid-derived suppressor cells (MDSC) have been thoroughly characterized in established SCC. However, it is unclear what precancerous lesions harbor a bona fide high risk for malignant transformation and how precancerous epithelial dysplasia drives the immune system to the point of no return.
