Advanced Science, EarlyView.Spermatogonial stem cells (SSCs) provide critical support to spermatogenesis. Here, the author established Il1r2 as a sorting marker for SSCs, with which further insights into the SSC heterogeneity and dynamic features can be obtained. They also confirmed findings in both mouse and human, thus validating IL1R2 as the surface marker for isolating and ...

Gender Differences in Bile Acids and Microbiota in Relationship with Gender Dissimilarity in Steatosis Induced by Diet and FXR Inactivation. [PDF]
, 2017 This study aims to uncover how specific bacteria and bile acids (BAs) contribute to steatosis induced by diet and farnesoid X receptor (FXR) deficiency in both genders.

Advanced Science, EarlyView.In PCOS patients with hyperandrogenemia, decreased ferritin heavy chain 1 (FTH1) causes Fe2⁺ overload and ferroptosis in trophoblasts. Androgens induce FTH1 protein degradation via AR‐LAMP2A‐mediated chaperone‐mediated autophagy pathway, leading to placental development disruption and early pregnancy loss. Metformin mitigates androgen‐induced placental

Differential Retinoic Acid Signaling in Tumors of Long- and Short-term Glioblastoma Survivors [PDF]
, 2017 Although the prognosis of most glioblastoma patients is poor, 3%-5% patients show long-term survival of 36 months or longer after diagnosis. To study the differences in activation of biochemical pathways, we performed mRNA and protein expression analyses

Optimisation of growth conditions for ovine airway epithelial cell differentiation at an air-liquid interface [PDF]
, 2018 Respiratory tract infections are of significant concern in the agriculture industry. There is a requirement for the development of well-characterised in vitro epithelial cell culture models in order to dissect the diverse molecular interactions occurring

Advanced Science, EarlyView.Researchers have developed a patient‐derived organ‐on‐a‐chip model for pancreatic cancer by integrating cancer cells with supportive stromal and immune cells inside a microfluidic device. This system mimics the tumor microenvironment, enabling personalized testing of chemotherapy and immunotherapy, and offering new insights into how targeting ...

Activation of Retinoic Acid Receptors by Dihydroretinoids [PDF]
Molecular Pharmacology, 2009 Vitamin A-derived metabolites act as ligands for nuclear receptors controlling the expression of a number of genes. Stereospecific saturation of the C(13)-C(14) double bond of all-trans-retinol by the enzyme, retinol saturase (RetSat), leads to the production of (R)-all-trans-13,14-dihydroretinol.

Association of retinoic acid receptor genes with meningomyelocele. [PDF]
, 2010 BACKGROUND: Neural tube defects (NTDs) occur in as many as 0.5-2 per 1000 live births in the United States. One of the most common and severe neural tube defects is meningomyelocele (MM) resulting from failed closure of the caudal end of the neural tube.
