Towards modeling enteric hyperoxaluria in a tripartite microbiota-gut-kidney microphysiological system in Microbiota and Host. By Consuelo Fabi et al. Figure 1. Modeling enteric hyperoxaluria in a microphysiological system. Handling of exogenous oxalate involves a first step in the intestinal mucosa, with the contribution of commensal microbes and the intestinal cell lining, and a second step in the kidneys with excretion in the urine. An alteration of intestinal mucosa in enteric hyperoxaluria is responsible for increased oxalate absorption and formation of oxalate stones in the kidneys (left panel). Enteric hyperoxaluria may be modeled in a microphysiological system that incorporates the intestinal mucosa with the epithelial cell lining and commensal microbes, as well as the different segments of the kidneys (the glomerular portion and the distal tubule are represented). The addition of gut stressors is added to mimic the intestinal pathology from which enteric hyperoxaluria originates (right panel). Microbiota and Host 3, 1; 10.1530/MAH-25-0009

A new review by Consuelo Fabi et al. discusses the strategies for enteric hyperoxaluria modeling in a microphysiological system and how these models could advance therapeutic discovery.

Sex hormones, sex chromosomes, and microbiota: identification of Akkermansia muciniphila as an estrogen-responsive bacterium in Microbiota and Host. By Anil Sakamuri et al. Figure 1. Plasma steroid analysis of gonadal intact and gonadectomized mice. Females: (A) Estradiol was significantly decreased by ovariectomy (P < 0.001) independent of sex chromosome complement. (B) The main effect of ovariectomy did not impact testosterone levels, but an increase was noted in XYF (P = 0.04). (C) There was an overall sex chromosome but not sex hormone effect in Aldosterone levels greater in XXF than XYF (P < 0.01). (D) Castrated male mice indicated no significant difference in estradiol levels (P = 0.5). (E) However, testosterone was significantly decreased in castrated mice (P < 0.0001) independent of the mice genotype. (F) There was no significant effect of castration on aldosterone levels (P = 0.9)...Microbiota and Host 1, 1; 10.1530/MAH-23-0010
