This is the first report in the literature concerning penile hypoplasia and rudimentary prepuce in a 78,XY; SRY-positive male that received a successful surgical treatment. A six-month-old male mixed-breed dog with body weight of 3.5 kg and with symptoms of prolonged stranguria and abnormalities of the external genitalia were presented by the owner at the University Surgical Clinic. Clinical, b...

Mammalian sex determination is controlled by the Y-linked gene SRY. Studies of sex-reversed patients and experimental data obtained with mice have identified other genes, such as DAX1, SOX9, SF1, and WT1, which take part in the process, and have suggested how these genes interact to determine the sex of a mammalian embryo. A recent paper in Nature by Swain et al. provides experimental data that...

ammalian sex-determining factors with homology to DNA binding proteins are required for splicing, according to a study by Paolo SassoneCorsi and coworkers at the Université Louis Pasteur (Strasbourg, France). Examination of high mobility group (HMG) domain containing SRY and Sox proteins demonstrated a surprising but clear association with splicing complexes. SRY, the testis-determining factor ...

اثر دو رقیق‌کننده مختلف تریس- زرده تخم‌مرغ و آندرومد بر کیفیت منی و نسبت جنسیت اسپرم گاو هلشتاین در طول فرآیند رقیق‌سازی و انجماد با استفاده از تکنیک real- time qPCR بررسی شد. این آزمایش با استفاده از چهار گاو نر نژاد هلشتاین در سن چهار سالگی و به‌مدت چهار هفته در قالب طرح کاملاً تصادفی انجام شد .ژنهای PLP و SRY به ترتیب برای جداسازی قطعات خاصی از توالی های کروموزوم X- و Y- تکثیر شدند. استفاده ا...

سابقه و هدف: تشخیص پیش از تولد(prenatal diagnosis) جنسیت جنین، نیازمند روش های تهاجمی نظیر نمونه گیری از طریق آمنیوسنتز و نمونه گیری از پرزهای کوریونی(cvs) می باشد. در سال های اخیر، یکی از روشهای غیر تهاجمی بررسی حضور dna سلولهای هسته دار جنینی در پلاسمای خون مادر است که در این تحقیق مورد بررسی قرار گرفت. روش بررسی: در این مطالعه تجربی، سیستم nested-pcr برای تشخیص ژن sry جنینی با بکارگیری dna ج...

The case of a 28 year old male with normal male phenotype, in whom repeated seminal analysis showed complete azoospermia, is presented. Peripheral blood culture for chromosome studies revealed 46 chromosomes with XX constitution. Polymerase chain reaction (PCR) analysis of genomic DNA failed to detect the presence of the sex-determining region of the Y chromosome (SRY). A literature review of a...

Developmental gene expression is defined through cross-talk between the function of transcription factors and epigenetic status, including histone modification. Although several transcription factors play crucial roles in mammalian sex determination, how epigenetic regulation contributes to this process remains unknown. We observed male-to-female sex reversal in mice lacking the H3K9 demethylas...
