Prevalence of Self-Reported Kidney Disease in Older Adults by Sexual Orientation: Behavioral Risk Factor Surveillance System Analysis (2014-2019).

Significance Statement: Studies discusses CKD disparities by age, race and ethnicity, and socioeconomics. However, despite well-documented disparities in CKD risk factors in LGBT+ adults, limited literature addresses CKD prevalence in this population. This analysis uses Behavioral Risk Factor Surveillance System (2014-2019) data to compare self-reported kidney disease prevalence in LGBT+ older adults (older than 50 years) with their heterosexual peers.

Intracellular sites of AQP2 S256 phosphorylation identified using inhibitors of the AQP2 recycling itinerary.

Vasopressin (VP)-regulated aquaporin-2 (AQP2) trafficking between cytoplasmic vesicles and the plasma membrane of kidney principal cells is essential for water homeostasis. VP affects AQP2 phosphorylation at several serine residues in the COOH-terminus; among them, serine 256 (S256) appears to be a major regulator of AQP2 trafficking. Mutation of this serine to aspartic acid, which mimics phosphorylation, induces constitutive membrane expression of AQP2.

Noncanonical SMC protein in Mycobacterium smegmatis restricts maintenance of Mycobacterium fortuitum plasmids.

Research on tuberculosis and leprosy was revolutionized by the development of a plasmid transformation system in the fast-growing surrogate, Mycobacterium smegmatis. This transformation system was made possible by the successful isolation of a M. smegmatis mutant strain mc(2)155, whose efficient plasmid transformation (ept) phenotype supported the replication of Mycobacterium fortuitum pAL5000 plasmids.
