Plant Biotechnology Journal, Volume 24, Issue 10, Page 5440-5459, October 2026.ABSTRACT Drought stress severely restricts rice productivity, necessitating strategies to enhance stress resilience. Here, we identify translation termination as a tunable regulatory node for stress adaptation. Using 25 rounds of SELEX, we isolated RTAR, an RNA aptamer that binds the rice eukaryotic release factor 1 (OseRF1) with nanomolar affinity ...

Experimental Physiology, Volume 111, Issue 10, Page 4763-4780, 1 October 2026.Abstract Skeletal muscle atrophy is a secondary complication in the aetiology of injury and chronic disease. Identifying mechanisms that control muscle mass is necessary to characterise atrophy and develop prevention strategies. We aimed to integrate transcriptomic and epigenomic data to identify key regulatory pathways controlled by promoter DNA ...

Site-specific phosphorylation of the α subunit of eukaryotic initiation factor eIF-2 by the heme-regulated and double-stranded RNA-activated eIF-2α kinases from rabbit reticulocyte lysates [PDF]
Proceedings of the National Academy of Sciences, 1980 The site specificity of phosphorylation of the α subunit of eukaryotic initiation factor 2 (eIF-2α) by the heme-regulated and double-stranded RNA-activated eIF-2α kinases were compared by phosphopeptide mapping. eIF-2α was maximally phosphorylated in vitro with [γ- 32

Advanced Science, Volume 13, Issue 52, 18 September 2026.RT promotes VG161 replication in BC and its immunostimulatory transgenes expression, which is mediated by the upregulation of GADD34 and HVEM caused by RT. The combination therapy with VG161 and RT increases the abundances of tumor‐infiltrating lymphocytes and elicits potent systemic antitumor immunity, thereby effectively inhibiting local tumors and ...

Advanced Science, Volume 13, Issue 50, 7 September 2026.This study uncovers that quercetin naturally targets mitochondria. By coordinating quercetin with Fe3+, we engineer an ultrasmall cascade nanozyme (MCN) with superoxide dismutase‐catalase activities. MCN crosses the damaged blood–brain barrier, scavenges mitochondrial ROS, prevents mitochondrial DNA leakage, and blocks the cGAS‐STING pathway, thereby ...

Journal of Biological Chemistry, 1994 To study further the regulation of the heme-regulated eIF-2 alpha kinase (HRI), we have produced functional wild type HRI using the baculovirus expression system. The amount of recombinant HRI protein expressed in insect cells is approximately 10 times higher than levels in reticulocytes. Baculovirus-expressed HRI (BV-HRI) is indistinguishable from HRI

Immunity, Inflammation and Disease, Volume 14, Issue 9, September 2026.Messenger RNA therapeutics are rapidly expanding beyond infectious diseases into oncology, autoimmune disorders, protein replacement therapy, cardiovascular and neurological diseases, and regenerative medicine. Advances in RNA engineering and targeted delivery are driving the development of safe, programmable, and precision therapeutics for diverse ...

Journal of Biological Chemistry, 1992 Inhibition of protein synthesis in rabbit reticulocyte lysates occurs in response to a variety of conditions including heme deficiency, addition of oxidants, and heat stress. The inhibition of translation is due to the activation of a heme-regulated protein kinase (HRI) which specifically phosphorylates the alpha-subunit of the eukaryotic initiation ...

Harnessing plant susceptibility genes into strategies for enhanced disease resistance
New Plant Protection, Volume 3, Issue 3, September 2026.Integrated model of S gene modules in plant pathogen interactions. This model summarises representative host susceptibility modules that can be exploited by bacterial, fungal and viral pathogens. In the bacterial infection module, Xanthomonas transcription activator‐like effectors activate OsSWEET14 through effector‐binding elements in its promoter ...

Indian journal of biochemistry & biophysics, 1995 Mechanism of regulation of eIF-2 alpha-subunit phosphorylation by dsI and p67 was studied. The results are as follows: (1) At low dsI concentration, p67 protected equimolar concentration of eIF-2. (2) At high dsI concentration, dsI efficiently phosphorylated eIF-2 alpha-subunit even when equimolar concentrations of both p67 and eIF-2 were present ...
