Filling metal-organic framework mesopores with TiO for CO photoreduction.

Metal-organic frameworks (MOFs) are known for their specific interactions with gas molecules; this, combined with their rich and ordered porosity, makes them promising candidates for the photocatalytic conversion of gas molecules to useful products. However, attempts to use MOFs or MOF-based composites for CO photoreduction usually result in far lower CO conversion efficiency than that obtained from state-of-the-art solid-state or molecular catalysts, even when facilitated by sacrificial reagents. Here we create 'molecular compartments' inside MOF crystals by growing TiO inside different pores of a chromium terephthalate-based MOF (MIL-101) and its derivatives.

Follistatin-like 1 as a Novel Adipomyokine Related to Insulin Resistance and Physical Activity.

SRSF1 regulates exosome microRNA enrichment in human cancer cells.

Background: Exosomes are extracellular vesicles containing a variety of biological molecules including microRNAs (miRNAs). We have recently demonstrated that certain miRNA species are selectively and highly enriched in pancreatic cancer exosomes with miR-1246 being the most abundant. Exosome miRNAs have been shown to mediate intercellular communication in the tumor microenvironment and promote cancer progression.

Mitochondrial GRIM-19 deficiency facilitates gastric cancer metastasis through oncogenic ROS-NRF2-HO-1 axis via a NRF2-HO-1 loop.

Background: NRF2, a prime target of cellular defense against oxidative stress, has shown a dark side profile in cancer progression. GRIM-19, an essential subunit of the mitochondrial MRC complex I, was recently identified as a suppressive role in tumorigenesis of human gastric cancer (GC). However, little information is available on the role of GRIM-19 and its cross-talk with NRF2 in GC metastasis.

The Effects of Puerarin on Autophagy Through Regulating of the PERK/eIF2α/ATF4 Signaling Pathway Influences Renal Function in Diabetic Nephropathy.

Background And Purpose: Autophagy is the main protective mechanism against aging in podocytes, which are terminally differentiated cells that have a very limited capacity for mitosis and self-renewal. Here, a streptozotocin-induced DN C57BL/6 mouse model was used to investigate the effects of puerarin on the modulation of autophagy under conditions associated with endoplasmic reticulum stress (ERS). In addition, this study aimed to identify the potential underlying molecular mechanisms.
