Abstract Homeostasis is one of the fundamental concepts in physiology. Despite remarkable progress our molecular understanding amino acid transport, metabolism and signaling, it remains unclear by what mechanisms cytosolic concentrations are maintained. We propose that transporters primary determinants intracellular levels. show a cell’s endowment with can be deconvoluted experimentally used this data to computationally simulate translocation across plasma membrane. Transport simulation...
Lack of B 0 AT1 (SLC6A19) partially protects mice against the onset non-alcoholic steatohepatitis (NASH). To achieve a similar outcome through pharmacological treatment, we improved previously identified inhibitors by medicinal chemistry and second generation high through-put screening. Modified diarylmethine compounds inhibited with IC 50 values ranging from 8–90 μM. A was derived high-throughput screening showed higher affinity (IC 1–15 μM) strong selectivity amino acid transporters...
Abstract Context The obesity epidemic parallels an increasing type 1 diabetes incidence, such that westernized diets, containing high fat, sugar and/or protein, through inducing nutrient-induced islet beta-cell stress, have been proposed as contributing factors. broad-spectrum neutral amino acid transporter (B0AT1), encoded by Slc6a19, is the major acids in intestine and kidney. B0AT1 deficiency C567Bl/6J mice, causes aminoaciduria, lowers insulinemia improves glucose tolerance. Objective We...
Amino acid transporters play a vital role in metabolism and nutrient signaling pathways. Typically, transport activity is investigated using single substrates competing amounts of other amino acids. We used GC-MS LC-MS for metabolic screening Xenopus laevis oocytes expressing various human incubated complex media to establish their comprehensive substrate profiles. For most transporters, selectivity matched reported However, we could not detect substantial accumulation cationic acids by...
Dietary protein restriction has beneficial impacts on metabolic health. B0AT1 (SLC6A19) is the major transporter of neutral amino acids at intestinal epithelia and absorbs bulk diet-derived from lumen. It also reabsorbs in renal proximal tubules. Mice lacking show cellular outcomes restriction, such as high FGF21 levels low mTORC1 activity. Moreover, they have improved glucose homeostasis resist diet-induced obesity. In this study, we investigated relationship between dietary intake C57Bl6/J...
In humans, ∼0.1% to 0.3% of circulating red blood cells (RBCs) are present as platelet-RBC (P-RBC) complexes, and it is 1% 2% in mice. Excessive P-RBC complexes found diseases that compromise RBC health (eg, sickle cell disease malaria) contribute pathogenesis. However, the physiological role healthy unknown. As a result damage accumulated over their lifetime, RBCs nearing senescence exhibit molecular changes akin those platelet-binding malaria. Therefore, we hypothesized targets for...
Recent studies have established that dietary protein restriction improves metabolic health and glucose homeostasis. SLC6A19 (B0AT1) is the major neutral amino acid transporter in intestine carries out bulk of absorption from diet. Mice lacking show signs restriction, improved tolerance, are protected diet-induced obesity. Pharmacological blockage this could be used to induce treat diseases such as type 2 diabetes. A few novel inhibitors recently been identified using vitro compound...
Intracellular parasites of the phylum Apicomplexa are dependent on scavenging essential amino acids from their hosts. We previously identified a large family apicomplexan-specific plasma membrane-localized acid transporters, ApiATs, and showed that Toxoplasma gondii transporter Tg ApiAT1 functions in selective uptake arginine. is for parasite virulence, but dispensable growth medium containing high concentrations arginine, indicating presence at least one other arginine transporter. Here we...
High protein feeding has been shown to accelerate the development of type 1 diabetes in female non-obese diabetic (NOD) mice. Here, we investigated whether reducing systemic amino acid availability via knockout Slc6a19 gene encoding system B(0) neutral transporter AT1 would reduce incidence or delay onset NOD deficient mice were generated using CRISPR-Cas9 which resulted marked aminoaciduria. The by week 30 was 59.5% (22/37) and 69.0% (20/29) NOD.Slc6a19+/+ NOD.Slc6a19−/− mice, respectively...

In Pakistan, although coverage of Maternal, Newborn, and Child Health (MNCH) services has increased, the attributable disease burden remains high, indicating quality these suboptimal. To address this gap, challenges associated with implementation MNCH will need to be addressed effective use various guidelines supported, evaluated, continuously improved. Even though application field science practice in low- middle-income settings been limited, it is our belief, based on experience described...
Objective: To assess the maternal outcome of primigravida patient with term pregnancy engaged versus unengaged foetal head at onset labour Design Study: It was a cohort study. Study Settings: The study conducted Department Obstetrics & Gynecology Rashid Latif Medical College, Lahore from January 2021 to June 2021. Material and Methods: This involved 160 (as per dating scan) aged between 18-35 years who were divided into cases (women fetal head) controls (those head). Outcome variable...
