DOI: 10.1002/elps.202200149 The cover picture shows how capillary-channeled polymer (C-CP) fibers are applied in a spin-down tip format to isolate pure, concentrated populations of exosomes and other extracellular vesicles (EVs) from human embryonic kidney (HEK) cell culture media. Exosomes/EVs vehicles intercellular communication, containing genetic protein contents the mother cell. Beyond bei...

Background: Understanding of cellular and molecular mechanisms involved in cell/tumor growth and progression has led to molecular-targeted therapy. HER1 and HER2 are two main oncogenic components of HER-receptor family considered as targets for cancer research and therapy. Reliable results of HER- related research and targeted therapies dependent upon cell line with known HER expression status....

We hypothesized that pazopanib is an inhibitor of cisplatin renal transporters OCT2, MATE1 and MATE2-K based on previous studies demonstrating an interaction between tyrosine kinase inhibitors and these transporters. Because several combinations of targeted therapies and cytotoxics are currently in development for cancer treatment, such an interaction is worth investigating. Experiments on HEK2...

Background: T cell Immunoglobulin, Mucin (TIM)-3, is a type I transmembrane glycoprotein belonging to TIM family. This receptor expresses on T helper type 1 (Th1) cells that binds to galectin-9 (Gal9); inducing an inhibitory signal. As a result, apoptosis of Th1 cells occurs and cytotoxicity of CD8 T cells becomes evident in vitro. Therefore, this immunomodulatory molecule may ...

Because HEK-293 cells are widely used for the functional expression of channels, exchangers and transporters involved in Ca(2+) homoeostasis, the properties of intracellular Ca(2+) stores and the methods used for measuring intracellular Ca(2+) release in HEK-293 cells were evaluated. Ca(2+) imaging was used to show caffeine-, carbachol- and thapsigargin-induced Ca(2+) release in HEK-293 cells t...

PTH-induced mobilization of cytosolic Ca2+ in a human kidney cell line (HEK/W) occurring in the absence of cAMP stimulation was characterized and compared with that obtained in the same cells stably transfected by the PTH/PTH-related peptide (PTHrp) receptor (HEK/T). In both cell lines, N-terminal fragments of PTH and PTHrp induced a concentration-dependent biphasic stimulation in [Ca2+]i: a tr...

انتقال ویروس کرونا به داخل سلول از طریق اسپایک‌های انجام می‌شود پس یکی بهترین راه‌های مقابله با سلول‌های بدن، ایجاد اختلال در روند عملکرد است. بنابراین این تحقیق، چگونگی جذب و انرژی پرتوهای رادیواکتیو سارس کووید2، مرس کووید، یوکی کووید توسط ابزار جینت4- دی اِن اِی شبیه‌سازی شده نتایج حاصل پرتودهی اسپایک‌ها یکدیگر مقایسه آن‌جایی که عوامل کاهش ماندگاری می‌باشد، پژوهش سعی است اسپایک ویروس­‌ها به‌وسی...

The Human Embryonic Kidney 293 cell line (HEK-293) readily lends itself to genetic manipulation and is a common tool for biologists to overexpress proteins of interest and study their function and molecular regulation. Although these cells have some limitations, such as an inability to form resistive monolayers necessary for studying transepithelial ion transport, they are nevertheless valuable...
