The Association of Neonatal Gut Microbiota Community State Types with Birth Weight.

Background: while most gut microbiota research has focused on term infants, the health outcomes of preterm infants are equally important. Very-low-birth-weight (VLBW) or extremely-low-birth-weight (ELBW) preterm infants have a unique gut microbiota structure, and probiotics have been reported to somewhat accelerate the maturation of the gut microbiota and reduce intestinal inflammation in very-low preterm infants, thereby improving their long-term outcomes. The aim of this study was to investigate the structure of gut microbiota in ELBW neonates to facilitate the early identification of different types of low-birth-weight (LBW) preterm infants.

[Expression of the D930020B18Rik gene in the mouse testis during spermatogenesis: Characteristics and potential role].

Objective: To investigate the expression pattern of the D930020B18Rik gene in the testis of the mouse in different stages of development and its possible role in spermatogenesis.

Machine learning approach identifies meconium metabolites as potential biomarkers of neonatal hyperbilirubinemia.

Background: The gut microbiota plays an important role in the early stages of human life. Our previous study showed that the abundance of intestinal flora involved in galactose metabolism was altered and correlated with increased serum bilirubin levels in children with jaundice. We conducted the present study to systematically evaluate alterations in the meconium metabolome of neonates with jaundice and search for metabolic markers associated with neonatal jaundice.

Transcriptional regulation of PEBP1 expression by androgen receptor in mouse testes.

Androgen and AR are essential for maintaining spermatogenesis and male fertility. Previous studies have shown that the phosphatidyl ethanolamine binding protein 1 () gene is down-regulated in the selective ablation of the AR in the Sertoli cells of mouse testes compared with wild-type mice, indicating that is a candidate target of AR. The ChIP-PCR data and ChIP-sequencing results of this study verified that is a target gene regulated by AR.
