Endocrine disruptors in Adansonia digitata (Linn) extract induce alteration of female Wistar rats' oestrous cycle, hormone and lipid profiles
CONCLUSION: AAMF fraction of A. digitata (L) root bark disrupts the endocrine activity in female Wistar rats. The oleic acid component of the AAMF fraction may be responsible for modulating the activities of reproductive hormones. The authors recommend further studies to ascertain the significance of Adansonia digitata extract's oleic acid in regulating the female reproductive cycle.PMID:37722461 | DOI:10.1016/j.ygcen.2023.114385 (Source: General and Comparative Endocrinology)

Does ghrelin regulate intestinal motility in rabbits? An in vitro study using isolated duodenal strips
In conclusion, ghrelin does not affect muscle contractility or motilin-induced contraction in the rabbit duodenum, which is due to the lack of ghrelin receptors. The present in vitro results suggest that ghrelin might not be a regulator of intestinal motility in rabbits.PMID:37722460 | DOI:10.1016/j.ygcen.2023.114384 (Source: General and Comparative Endocrinology)

Progesterone receptors in extra testicular ducts of the Amazonian stingray Potamotrygon wallacei: a potential role in sperm maturation and aggregate formation
Gen Comp Endocrinol. 2023 Sep 9:114375. doi: 10.1016/j.ygcen.2023.114375. Online ahead of print.ABSTRACTIn cururu stingray (Potamotrygon wallacei Carvalho, Rosa and Araújo 2016) males, plasma progesterone (P4) levels appear to be associated with spermiation events. However, the specific contribution of P4 in sperm maturation via extratesticular ducts in this stingray species is unknown. With the aim of filling this knowledge gap, this study examined the morphology and the presence of progesterone receptors (PR) in the ducts, and analyzed the relationship of progesterone (P4) with sperm maturation and formation of aggregat...

Dual roles of crustacean female sex hormone during juvenile stage in the kuruma prawn Marsupenaeus japonicus
Gen Comp Endocrinol. 2023 Sep 6;344:114374. doi: 10.1016/j.ygcen.2023.114374. Online ahead of print.ABSTRACTThe crustacean female sex hormone (CFSH) has been identified as a female-specific hormone that plays a crucial role in female phenotype developments in the blue crab Callinectes sapidus. To date, its homologous genes have been reported in various decapod species. Additionally, unlike the blue crab, several species have two different CFSH subtypes. The kuruma prawn Marsupenaeus japonicus is a representative example species of this phenomenon, having two CFSH subtypes identified from the eyestalk (MajCFSH) and ovary (M...
