HSCB, a co-chaperone in mitochondrial iron-sulfur cluster biogenesis, is a novel candidate gene for congenital sideroblastic anemia [PDF]

open access: yes, 2017
Congenital sideroblastic anemias (CSA) are inherited diseases resulting from defects in heme biosynthesis, mitochondrial iron-sulfur cluster (ISC) assembly, or mitochondrial translation.

Application and Challenges of Chimeric Antigen Receptor T Cell Therapy in Systemic Rheumatic Diseases and Autoimmune Disorders

open access: yesMedComm, Volume 7, Issue 4, April 2026.
CAR‐T cell therapy in systemic rheumatic diseases and autoimmune disorders. (This figure was created using BioRender.com.) ABSTRACT Chimeric antigen receptor T (CAR‐T) cell therapy, originally developed for hematologic malignancies, has emerged as a transformative candidate for systemic rheumatic diseases and autoimmune disorders (AIDs).

Extracellular and Membrane Protein: Structure, Biological Functions, Diseases, and an Emerging Modality for Drug Discovery

open access: yesMedComm, Volume 7, Issue 4, April 2026.
Targeted protein degradation represents a paradigm shift from traditional protein inhibition to complete protein elimination. This is achieved through three main strategies for degrading extracellular and membrane proteins: recruitment of cell‐surface LTRs, engagement of intracellular proteins, and receptor‐independent mechanisms.

MPRAnalyze: statistical framework for massively parallel reporter assays. [PDF]

open access: yes, 2019
Massively parallel reporter assays (MPRAs) can measure the regulatory function of thousands of DNA sequences in a single experiment. Despite growing popularity, MPRA studies are limited by a lack of a unified framework for analyzing the resulting data ...

Post‐translational Modifications in Proteins: Prediction Methods, Biological Functions, and Diseases

open access: yesMedComm, Volume 7, Issue 4, April 2026.
Posttranslational modifications (PTMs) serve as rapid and reversible molecular switches that reshape protein activity, stability, and interactomes, thereby governing virtually all physiological cues ranging from signal transduction to epigenetic memory. Mass spectrometry‐based proteomics has substantially expanded our understanding of PTM emergence and

Disarming the Hsp70–Bim Alliance: Small‐Molecule and Peptidic Disruptors of a Chaperone‐Apoptotic Switch in Cancer

open access: yesChemistryOpen, Volume 15, Issue 4, April 2026.
Targeting a nucleotide‐sensitive groove on Hsp70 that binds the Bim BH3 helix, we integrate structures, biophysics, and SAR from peptides, fragments, and phenalene‐dicarbonitrile “wedges.” These disrupt the Hsp70–Bim complex with sub‐µM cellular engagement and in vivo activity while sparing Hsp90/mortalin.

姜黄素调控自噬抑制K562细胞增殖的体外研究

open access: yesZhongguo shiyan zhenduanxue, 2018
目的研究姜黄素诱导自噬对K562细胞增殖的影响。方法采用1、5、10、20和40μM/L姜黄素及自噬抑制剂3-MA作用于K562细胞24h,采用MTT实验观察K562细胞增殖变化情况,随后采用Western-blot检测自噬标志蛋白LC3-II/LC3-I变化水平;同时Western blot分析p53,p21和p27表达变化。结果姜黄素能以时间、剂量依赖性方式抑制K562细胞增殖,与3-MA对照组相比,LC3-II/LC3-I比值显著上升,姜黄素诱导K562细胞周期停滞,上调p53 ...
