中文摘要:MAPK信号通路对哺乳动物的精子发生与凋亡有重要的调节作用,被认为是精子发生的重要决定因素之一。本研究通过比较MAPK信号通路中 ERK1、ERK2、P38基因在牦牛及其杂交后代犏牛睾丸组织中的相对表达量,探索犏牛雄性不育的分子机制。实验从成年雄性牦牛( n=10)和
Lactational quantity of the control group was significantly lower than those which had been feed three different feed formulas in winter and summer.On the other hand,milk nutritional component of cattle-yaks was slightly high.But,milk protein,butterfat rate,lactose and additional indicators were not...
The results revealed that male cattle-yaks presented smaller testes (5.933 卤 0.4885 cm vs. 7.150 卤 0.3937 cm), with only single cell layers in seminiferous tubules, and weakened signals of m6A regulators such as METTL14 (methyltransferase-like 14), ALKBH5 (alpha-ketoglutarate-dependent ...
The average copy numbers of TSPY-T2 and ZNF280BY were significantly different between cattle and yaks. The TSPY-T2, TSPY2, PRAMEY, ZNF280BY, and HSFY genes were uniquely or predominantly expressed in testes. Reverse-transcription quantitative PCR showed that the TSPY-T2, PRAMEY-T2, HSF...
To study the physiological characterization of blood for hypoxia adaptation in yaks and Tibetan cattle,the blood physiological parameters and hemorheological indexes of 246 cattle at 4 altitudes of the Yunnan- Tibet line were determined,including Honghe cattle and Pingbian cattle at the altitude of 1...
