Retinoic Acid Signaling during Early Spinal Cord Development
Journal of Developmental Biology, 2014 Retinoic acid signaling is required at several steps during the development of the spinal cord, from the specification of generic properties to the final acquisition of neuronal subtype identities, including its role in trunk neural crest development ...

PSMA8‐Containing 20S Proteasome Regulates Spermiogenesis and Male Fertility
Advanced Science, EarlyView.PSMA8 assembles s20S proteasome that degrades specific substrates in elongating spermatids. Degradation of s20S‐substrates activates translation of FXR1‐target mRNAs, which are essential for mitochondrial sheath formation and sperm morphogenesis.

Advanced Science, EarlyView.ABSTRACT Intestinal ischemia/reperfusion (I/R) injury presents a biphasic pathology: an acute oxidative‐inflammatory phase leading to organ failure, and a recovery phase marked by mucosal dysfunction and bacterial translocation. The developed MPB@TA‐Cu‐Ma nanocomposite functions as a dual‐phase therapeutic platform with significant efficacy. It rapidly

A paradoxical teratogenic mechanism for retinoic acid
, 2012 Retinoic acid, an active metabolite of vitamin A, plays essential signaling roles in mammalian embryogenesis. Nevertheless, it has long been recognized that overexposure to vitamin A or retinoic acid causes widespread teratogenesis in rodents as well as ...

Acute Myelogenous Leukemia without Maturation with a Retinoic Alpha-Receptor Deletion: A Case Report
Case Reports in Oncology, 2014 Acute promyelocytic leukemia (APL) is characterized by a t(15;17) which fuses the 17q retinoic acid alpha-receptor sequence to the 15q PML gene sequence.

The Roles of Retinoic Acid and Retinoic Acid Receptors in Inducing Epigenetic Changes [PDF]
, 2014 Epigenetics is "the branch of biology which studies the causal interactions between genes and their products which bring the phenotype into being" as defined by Conrad Waddington in 1942 in a discussion of the mechanisms of cell differentiation.

Retinoic acid differentially regulates the migration of innate lymphoid cell subsets to the gut
Immunity, 2015 Summary Distinct groups of innate lymphoid cells (ILCs) such as ILC1, ILC2 and ILC3 populate the intestine, but how these ILCs develop tissue tropism for this organ is unclear.
