H2‐dependent modulation of tetrahydromethanopterin S‐methyltransferase (Mtr complex) activity by the small protein MtrR in Methanosarcina mazei

The FEBS Journal, EarlyView.
Small protein MtrR is a regulator of the Mtr methyltransferase complex in Methanosarcina mazei. It binds specifically to the MtrA subunit and modulates Mtr activity in response to hydrogen (H2) availability. Deleting mtrR impairs growth in the presence but not absence of H2, indicating its role in directing methyl transfer toward an energy‐conserving ...

Poplar miR1447 Is a Negative Regulator of Disease Resistance Through the SA‐Dependent Pathway

Plant Biotechnology Journal, EarlyView.
ABSTRACT Although microRNA1447 (miR1447) regulates poplar responses to abiotic stress and pest infestation, how miR1447 regulates poplar immunity against pathogens and its underlying molecular mechanisms remain to be elucidated. Here, we revealed that miR1447 functioned as a negative regulator of poplar disease resistance against fungal and bacterial ...

Genomic alterations in primary gastric adenocarcinomas correlate with clinicopathological characteristics and survival. [PDF]

, 2004
Background & aimsPathogenesis of gastric cancer is driven by an accumulation of genetic changes that to a large extent occur at the chromosomal level. In order to investigate the patterns of chromosomal aberrations in gastric carcinomas, we performed

RUBBER BAND LIGATION FOR HEMORRHOIDS (review)

Koloproktologia, 2019
Rubber band ligation is one of the most common and effective minimally invasive methods of treatment of chronic hemorrhoids. An analysis of the experience gained in the use of latex ligation makes it possible to evaluate the advantages and disadvantages of this technique and suggest new options for its implementation.

HIF‐1α/Netrin‐4 Axis Mediates RIPC‐Induced Angiogenesis and Neurogenesis After Ischemic Stroke

Journal of Cellular and Molecular Medicine, Volume 30, Issue 7, April 2026.
ABSTRACT Remote ischemic postconditioning (RIPC) confers neuroprotection in ischemic stroke partly via promoting angiogenesis and neurogenesis, but its precise molecular mechanisms remain unclear; here, we investigated the role of the secreted guidance protein Netrin‐4 (NTN4) and its upstream regulator hypoxia‐inducible factor 1α (HIF‐1α) in mediating ...
