Parthenolide improves sepsis-induced coagulopathy by inhibiting mitochondrial-mediated apoptosis in vascular endothelial cells through BRD4/BCL-xL pathway by Jun Zhang, Xing Zhu, Yong Li, Yinyu Wu, Yunxia Du, Hai Yang, Zhengchao Liu, Haoyu Pei, Rui Li, Huan Luo, Deyu Zuo, Han She, Qingxiang Mao

“…PTL treatment also enhances coagulation function, augments vascular endothelial cell (VEC) function, reduces mitochondrial fragmentation, and increases both mitochondrial oxygen consumption rate (OCR) and mitochondrial membrane potential (MMP), while inhibiting reactive oxygen species (ROS) production. By increasing BRD4/BCL-xL levels, PTL can prevent mitochondrial-mediated apoptosis in VECs, improve VEC function, and consequently ameliorate SIC. …”

Release of P-TEFb from the Super Elongation Complex promotes HIV-1 latency reversal. by William J Cisneros, Shimaa H A Soliman, Miriam Walter, Lacy M Simons, Daphne Cornish, Simone De Fabritiis, Ariel W Halle, Eun-Young Kim, Steven M Wolinsky, Ramon Lorenzo-Redondo, Ali Shilatifard, Judd F Hultquist

“…Blocks to transcriptional elongation play a central role in maintaining the latent state, and several latency reversal strategies focus on the release of positive transcription elongation factor b (P-TEFb) from sequestration by negative regulatory complexes, such as the 7SK complex and BRD4. Another major cellular reservoir of P-TEFb is in Super Elongation Complexes (SECs), which play broad regulatory roles in host gene expression. …”

Comprehensive genomic profiling of primary bladder mucinous adenocarcinoma, a rare genitourinary cancer: A case report by Shinkuro Yamamoto, Shingo Ashida, Tomoya Nao, Kaho Murakami, Ryohei Iga, Tsutomu Shimamoto, Hideo Fukuhara, Nobutaka Shimizu, Satoshi Fukata, Atsushi Kurabayashi, Takashi Karashima, Keiji Inoue

“…After two cycles of TIP therapy, FoundationOne CDx, a comprehensive genomic profiling test, was performed, revealing variants in ATM, SMAD4, BRD4, and NOTCH3. These genomic profiling test results may lead to the development of novel therapeutic agents for primary bladder mucinous adenocarcinoma.…”
