CDK4/6 inhibitors are effective in treating HR/HER2 breast cancer but face limitations due to therapeutic resistance and hematological toxicity, particularly from strong CDK6 inhibition. To address these challenges, designing selective inhibitors targeting specific cyclin-dependent kinases (CDK) members could offer clinical advantages and broaden CDK inhibitor indications. However, the highly conserved binding pockets of CDKs complicate selective targeting.

Helices are important secondary structural motifs within proteins and are pivotal in numerous physiological processes. While amino acids (AA) such as alanine and leucine are known to promote helix formation, proline and glycine disfavor it. Helical structure formation, however, also depends on its environment, and hence, prior prediction of a mutational effect on a helical structure is difficult.

Study Question: Is there an association between the somatic loss of PTEN (phosphatase and tensin homolog) and ARID1A (AT-rich interaction domain 1A) and endometriosis disease severity and worse clinical outcomes?
Summary Answer: Somatic PTEN loss in endometriosis epithelium was associated with greater disease burden and subsequent surgical complexity.
What Is Known Already: Somatic cancer-driver mutations including those involving the PTEN and ARID1A genes exist in endometriosis without cancer; however, their clinical impact remains unclear.
Study Design, Size, Duration: This prospective longitudinal study involved endometriosis tissue and clinical data from 126 participants who underwent surgery at a tertiary center for endometriosis (2013-2017), with a follow-up period of 5-9 years.

Sleep deprivation (SD) causes circadian misalignment, and circadian clock disruption is associated with metabolic diseases such as obesity, insulin resistance, and diabetes. However, the underlying mechanism for SD-induced circadian clock disruption as well as metabolic enzyme changes is still lacking. Here, we developed SD sensitizes mice with disrupted circadian rhythms to demonstrate the regulation role and mechanism of SD in UDP-glucuronosyltransferases (UGTs) expression and the metabolism of corresponding substrates.
