REDD1 Is a Promising Therapeutic Target to Combat the Development of Diabetes Complications: A Report on Research Supported by Pathway to Stop Diabetes.

The stress response protein regulated in development and DNA damage response 1 (REDD1) has emerged as a key player in the pathogenesis of diabetes. Diabetes upregulates REDD1 in a variety of insulin-sensitive tissues, where the protein acts to inhibit signal transduction downstream of the insulin receptor. REDD1 functions as a cytosolic redox sensor that suppresses Akt/mTORC1 signaling to reduce energy expenditure in response to cellular stress.

QTL mapping: insights into genomic regions governing component traits of yield under combined heat and drought stress in wheat.

Drought and heat frequently co-occur during crop growth leading to devastating yield loss. The knowledge of the genetic loci governing component traits of yield under combined drought and heat stress is essential for enhancing the climate resilience. The present study employed a mapping population of 180 recombinant inbred lines (RILs) derived from a cross between GW322 and KAUZ to identify quantitative trait loci (QTLs) governing the component traits of yield under heat and combined stress conditions.

Cranberry Proanthocyanidins Mitigate Reflux-Induced Transporter Dysregulation in an Esophageal Adenocarcinoma Model.

We recently reported that cranberry proanthocyanidins (C-PACs) inhibit esophageal adenocarcinoma (EAC) by 83% through reversing reflux-induced bacterial, inflammatory and immune-implicated proteins and genes as well as reducing esophageal bile acids, which drive EAC progression. This study investigated whether C-PACs' mitigation of bile reflux-induced transporter dysregulation mechanistically contributes to EAC prevention. RNA was isolated from water-, C-PAC- and reflux-exposed rat esophagi with and without C-PAC treatment.

A single photoreceptor splits perception and entrainment by cotransmission.

Vision enables both image-forming perception, driven by a contrast-based pathway, and unconscious non-image-forming circadian photoentrainment, driven by an irradiance-based pathway. Although two distinct photoreceptor populations are specialized for each visual task, image-forming photoreceptors can additionally contribute to photoentrainment of the circadian clock in different species. However, it is unknown how the image-forming photoreceptor pathway can functionally implement the segregation of irradiance signals required for circadian photoentrainment from contrast signals required for image perception.

Marker-assisted selection for transfer of QTLs to a promising line for drought tolerance in wheat ( L.).

Wheat crop is subjected to various biotic and abiotic stresses, which affect crop productivity and yield. Among various abiotic stresses, drought stress is a major problem considering the current global climate change scenario. A high-yielding wheat variety, HD3086, has been released for commercial cultivation under timely sown irrigated conditions for the North Western Plain Zone (NWPZ) and North Eastern Plain Zone NEPZ of India.

Mapping of the QTLs governing grain micronutrients and thousand kernel weight in wheat ( L.) using high density SNP markers.

Biofortification is gaining importance globally to improve human nutrition through enhancing the micronutrient content, such as vitamin A, iron, and zinc, in staple food crops. The present study aims to identify the chromosomal regions governing the grain iron concentration (GFeC), grain zinc concentration (GZnC), and thousand kernel weight (TKW) using recombinant inbred lines (RILs) in wheat, developed from a cross between HD3086 and HI1500. The experiment was conducted in four different production conditions at Delhi , control, drought, heat, and combined heat and drought stress and at Indore under drought stress.

Genetic dissection of marker trait associations for grain micro-nutrients and thousand grain weight under heat and drought stress conditions in wheat.

Introduction: Wheat is grown and consumed worldwide, making it an important staple food crop for both its calorific and nutritional content. In places where wheat is used as a staple food, suboptimal micronutrient content levels, especially of grain iron (Fe) and zinc (Zn), can lead to malnutrition. Grain nutrient content is influenced by abiotic stresses, such as drought and heat stress.

Health system resilience: Ensuring TB services during COVID-19 pandemic in Kerala, India.

COVID-19 pandemic has affected TB case detection and continuity of care globally. Kerala, the southern Indian state has experienced a reduction in TB notification during second and third quarter of 2020. Through (1) causal analysis (2) meticulous planning and establishment of systems (3) locally customised guidelines (4) better management of resources (5) integration with other programs and (6) good partnership with private sector, Kerala was able to catch up the TB notification and ensure that TB services remain intact even during the COVID-19 pandemic.

Frailty Index (mFI-5) Predicts Resource Utilization after Nonruptured Endovascular Aneurysm Repair.

Introduction: The 5- factor frailty index (mFI-5) has reliably predicted outcomes after vascular surgeries. The purpose of this study was to determine the performance of this index in aortic endovascular surgery ( endovascular aneurysm repair [EVAR]) MATERIALS AND METHODS: The American College of Surgeons' National Surgical Quality Improvement Program Database (NSQIP) was retrospectively analyzed for patients undergoing nonruptured EVAR between 2015 and 2019. Outcomes were assessed using bivariate analysis (Mann Whitney U test, chi-squared test, and t-test) and multivariate logistic regression analysis.

PERK/ATF4-dependent expression of the stress response protein REDD1 promotes proinflammatory cytokine expression in the heart of obese mice.

Endoplasmic reticulum (ER) stress and inflammation are hallmarks of myocardial impairment. Here, we investigated the role of the stress response protein regulated in development and DNA damage 1 (REDD1) as a molecular link between ER stress and inflammation in cardiomyocytes. In mice fed a high-fat high-sucrose (HFHS, 42% kcal fat, 34% sucrose by weight) diet for 12 wk, REDD1 expression in the heart was increased in coordination with markers of ER stress and inflammation.

Marker assisted improvement for leaf rust and moisture deficit stress tolerance in wheat variety HD3086.

There is a significant yield reduction in the wheat crop as a result of different biotic and abiotic stresses, and changing climate, among them moisture deficit stress and leaf rust are the major ones affecting wheat worldwide. HD3086 is a high-yielding wheat variety that has been released for commercial cultivation under timely sown irrigated conditions in the Indo-Gangetic plains of India. Variety HD3086 provides a good, stable yield, and it is the choice of millions of farmers in India.

Identification of genomic regions of wheat associated with grain Fe and Zn content under drought and heat stress using genome-wide association study.

Wheat is the staple food crop of global importance for its grain nutrient quality. Grain iron and zinc content of the wheat grain is an important quantitatively inherited trait that is influenced by the environmental factors such as drought and heat stress. Phenotypic evaluation of 295 advanced breeding lines from the wheat stress breeding program of IARI was carried out under timely sown irrigated (IR), restricted irrigated, and late-sown conditions at New Delhi during the cropping season of 2020-21, and grain iron (GFeC) and zinc (GZnC) contents were estimated from both control and treatments.

Spleen Tyrosine Kinase Contributes to Müller Glial Expression of Proangiogenic Cytokines in Diabetes.

Purpose: Neuroglial dysfunction occurs early in the progression of diabetic retinopathy. In response to diabetes or hypoxia, Müller glia secrete cytokines and growth factors that contribute to disease progression. This study was designed to examine common signaling pathways activated in Müller glia by both type 1 and pre-/type 2 diabetes.

Warhorses in soil bioremediation: Seed biopriming with PGPF secretome to phytostimulate crop health under heavy metal stress.

The fungal symbiosis with the plant root system is importantly recognized as a plant growth promoting fungi (PGPFs), as well as elicitor of plant defence against different biotic and abiotic stress conditions. Thus PGPFs are playing as a key trouper in enhancing agricultural quality and increased crop production and paving a way towards a sustainable agriculture. Due to increased demand of food production, the over and unscientific usage of chemical fertilizers has led to the contamination of soil by organic and inorganic wastes impacting on soil quality, crops quality effecting on export business of agricultural products.
