TAp63γ is the primary isoform of TP63 for tumor suppression but not development by Xinbin Chen, Wenqiang Sun, Xiangmudong Kong, Xin Ming, Yanhong Zhang, Wensheng Yan, Shakur Mohibi, Mingyi Chen, Keith Mitchell, Jin Zhang

“…Single-cell RNA-seq revealed that loss of p63γ increases the expression of SCD1, a rate-limiting enzyme for synthesis of monounsaturated fatty acids, leading to altered lipid homeostasis. Together, our data indicate that TP63γ is the primary isoform of TP63 for tumor suppression but not development by maintaining normal inflammatory response and lipid homeostasis.…”

Performance of 1-year-old camel calves fed a basal ration of alfalfa hay supplemented with different levels of concentrate by Ahmed R. Askar, Rawia Darwesh, Sabbah Allam, Galal M. Abdul Aziz, Afaf A. El Shereef, Ehab Y. Eid, Hamedi M. Kandil, Samir S. Abou El Ezz, Mohsen M. Shoukry

“…Camel calves fed low vs. medium or high levels of concentrate showed a greater rumen pH (P < 0.05), which was linked to a lower concentration of volatile fatty acids (P < 0.010). Conclusions The present study concluded that yearling camel calves receiving different levels of concentrate with ad lib alfalfa hay could cover their nutrient requirements for maintenance and growth with a daily gain of 630 g/day when the level of concentrate was limited to 0.7% of BW and the total intake was only around 1.65% of BW, or 70.6 g/kg metabolic BW.…”
