Effects of Clomiphene citrate on Reproductive System of Birds and Mammals

Muhammad Zubair, Sajid Mahmood Sajid

...strogen receptors in the hypothalamus, inhibiting negative feedback of estrogen on gonadotropin release and leading to up-regulation of ovulation. It has useful effects on the reproduction of female in terms of reduction in puberty and ovulation induction. The beneficial effects are manifested in male in terms of improvement of semen.

Possible Role of Neuromedin S (NMS) in Male Reproduction: Effect of NMS on Adipokines Secretion in Male Rhesus Monkeys (Macaca mulatta)

Shakeel Ahmed* and Sarwat Jahan

...ent in the regulation of hypothalamus pituitary gonadal (HPG) axis has also been established. In the present study, we investigated the role of peripheral administration of neuromedin S (NMS) on adipokines (adiponectin, leptin and resistin) secretion in 48-h fasting and normal fed adult male Rhesus monkeys. After NMS administration plasma adipokines levels were determined in fed and fasting monkeys. Four intact adult male monkeys were used in this study. 50 nm...

...tested tissues, with the hypothalamus showing the highest expression in gibel carp. The npy mRNA expression in the hypothalamus significantly decreased 1 and 3 h after feeding (P < 0.01). Furthermore, its expression in the hypothalamus was significantly increased after fasting for 7 days and declined 2 days after refeeding (at 11-day and 14 -day; P < 0.01), sugge...

Expression Analysis of BMPR1B, BMP15, GDF9, Smad1, Smad5, and Smad9 in Rams with Different Fecundity

...n the brain, cerebellum, hypothalamus, pituitary, testis, epididymis, vas deferens, and adrenal gland in high fecundity (Small Tail Han sheep) and low fecundity (Sunite sheep) rams. The results were as follows: BMPR1B, GDF9, Smad1, Smad5 and Smad9 were expressed in all selected tissues, but BMP15 was specifically expressed in the epididymis. Further study indicated that the expression of BMPRIB in the brain,

Concentration Dependent Functions of FGF10 in Angiogenesis and Axon Guidance

Fang Liu*

...expressed in the ventral hypothalamus, plays important roles in axon guidance and in vasculature guidance of the developing hypothalamus. Here, using ex vivo analyses in chick, we show that FGF10 exerts concentration dependent functions in angiogenesis and hypothalamic axon guidance. At lower concentration of 100ng/ml, FGF10 promotes angiogenesis in chorioallantoic membrane endothelial capillaries (CAMs), but FGF10 do...

Faster Response to High-Fat Diet in Body Mass Regulation from Lower Altitude Population in Eothenomys miletus from Hengduan Mountain Regions

Gong Xue-na¹, Jia Ting², Zhang Di² and Zhu Wanlong¹*

...le effects on leptin and hypothalamus Neuropeptide Y (NPY) expression, and leptin positively correlated with body mass and negatively correlated with NPY expression. Moreover, E. miletus from two regions showed some physiological differences, such as RMR and food intake in XGLL were higher than that of JC, but body mass was lower than that of JC. Body mass reduced quickly inJC after re-feeding LF diet, while it decreased body mass gradually in XGLL. All...

Comparison of Expression Patterns of Six Canonical Clock Genes in Year-Round Estrous and Seasonal Estrous Rams

...ed in brain, cerebellum, hypothalamus, pituitary, testis, epididymis, vas deferens and adrenal gland tissues in both breeds. The expression level of Clock and BMAL1 showed similar trends in the brain, cerebellum, hypothalamus, pituitary, testis and epididymis in both breeds. The expression levels of Clock, BMAL1, and Cry1 were significantly higher in the pituitary tissue of STH rams than in...

Cloning and Bioinformatics of CTSD Gene and its Expression at the Onset of Puberty in Duolang Sheep

Qingjin Li^1,2, Zhiyuan Sui^1,2, Jihu Zhang^1,2, Zhishuai Zhang^1,2 and Feng Xing^1,2*

...TSD were detected in the hypothalamus, pituitary, ovary, uterus and oviduct in the three development periods of prepuberty, puberty, and postpuberty. The results showed that the coding region of CTSD gene of Duolang sheep had a full length of 1,239 bp, encoding 412 amino acids. The sequence of Duolang sheep CTSD was relatively similar to those of other mammals and was in line with evolutionary relationship. The mRNA of CTSD gene was expressed in all the tissue...
