Selective regulation of chemosensitivity in glioblastoma by phosphatidylinositol 3-kinase beta

iScience
Summary: Resistance to chemotherapies such as temozolomide is a major hurdle to effectively treat therapy-resistant glioblastoma. This challenge arises from the activation of phosphatidylinositol 3-kinase (PI3K), which makes it an appealing therapeutic ...

Interaction of mycobacterium tuberculosis with the host cells: a focus in the molecular mechanism involved in trafficking and autophagy [PDF]

, 2018
Tuberculosis (TB) is an ancient disease remaining a serious health threat worldwide. It is caused by Mycobacterium tuberculosis (Mtb), an acid-fast bacilli, non-sporulated, slow-growing, immobile and aerobic.

Sensing and Reprogramming Surface Receptor Activation With Synthetic Transcriptional Circuits

Advanced Science, EarlyView.
A synthetic receptor‐signalling induced transcription (RESIT) circuit is designed based on receptor activation mediated split protease complementation and release of membrane‐tethered synthetic transcriptional modules. The RESIT system enables probing Ca2+ entry, receptor tyrosine kinase (RTK) activities and Ras activation, and reprogramming RTK ...

Engineering Approaches to Modify Immunomodulatory Functions of Mesenchymal Stromal Cells (MSCs): Tissue Regeneration and Clinical Application

Advanced Science, EarlyView.
Mesenchymal stromal cells (MSCs) show promise for treating immune‐related disorders through immunomodulation and tissue regeneration. This review gives a brief overview of current clinical approval of MSC therapies. It also discussed how bioengineering, including genetic modification, biomaterial delivery, extracellular vesicles, and iPSC‐derived MSCs,

Phosphoinositide 3-kinase: friend and foe in cardiovascular disease

Frontiers in Pharmacology, 2015
Class I phosphoinositide 3-kinases (PI3Ks) are a family of lipid kinases activated by cell membrane receptors, either receptor tyrosine kinases (RTKs) or G protein-coupled receptors (GPCRs), to catalyze the production of the lipid second messenger ...

PIK3CA Mutations Downregulate PPT1 to Promote Adipogenesis by Suppressing P300 Depalmitoylation and Phase Separation

Advanced Science, EarlyView.
This study demonstrates that somatic PIK3CA mutations suppress PPT1 expression via activation of the PI3K–AKT–c‐JUN axis. This reduction in PPT1 weakens its interaction with P300, thereby increasing palmitoylation at C1176 of P300 and protecting P300 from lysosomal degradation.

Affinity‐Based Interactome Mapping of Inositol Pyrophosphates Reveals 4/6‐PP‐InsP5‐Binding Proteins in Plants

Advanced Science, EarlyView.
ABSTRACT Inositol pyrophosphates (PP‐InsPs) are central regulators of eukaryotic signaling events. While certain PP‐InsP isomers have been conclusively linked to the regulation of phosphate homeostasis through interaction with SPX domain‐containing proteins in plants, the functions of the recently discovered isomer 4/6‐PP‐InsP5 remain largely unknown ...

A p85 isoform switch enhances PI3K activation on endosomes by a MAP4- and PI3P-dependent mechanism

Cell Reports
Summary: Phosphatidylinositol 3-kinase α (PI3Kα) is a heterodimer of p110α catalytic and p85 adaptor subunits that is activated by agonist-stimulated receptor tyrosine kinases.

Fixed‐Duration Subcutaneous Mosunetuzumab in Relapsed/Refractory Follicular Lymphoma: Pivotal Phase 2 Primary Analysis

American Journal of Hematology, EarlyView.
ABSTRACT Mosunetuzumab is approved as an intravenous (IV) formulation for relapsed/refractory (R/R) follicular lymphoma (FL) after ≥ 2 prior therapies. A subcutaneous (SC) formulation, aiming to improve patient safety and convenience, has been developed.
