Drug-Resistant Urothelial Cancer Cell Lines Display Diverse Sensitivity Profiles to Potential Second-Line Therapeutics

Translational Oncology, 2015
Combination chemotherapy with gemcitabine and cisplatin in patients with metastatic urothelial cancer of the bladder frequently results in the development of acquired drug resistance.

Molecular actions of hypocholesterolaemic compounds from edible mushrooms [PDF]

, 2018
Cholesterol levels are strictly regulated to maintain its homeostasis; therefore, if it is not absorbed with the diet, the cholesterol biosynthetic pathway is enhanced and vice versa.

Inconsistent Transcriptomic Responses to Hexabromocyclododecane in Japanese Quail: A Comparative Analysis of Results From Four Different Study Designs

Environmental Toxicology and Chemistry, EarlyView.
Abstract Efforts to use transcriptomics for toxicity testing have classically relied on the assumption that chemicals consistently produce characteristic transcriptomic signatures that are reflective of their mechanism of action. However, the degree to which transcriptomic responses are conserved across different test methodologies has seldom been ...

Boosted coupling of ATP hydrolysis to substrate transport upon cooperative estradiol-17-beta-D-glucuronide binding in a Drosophila ATP binding cassette type-C transporter [PDF]

, 2018
ATP binding cassette type-C (ABCC) transporters move molecules across cell membranes upon hydrolysis of ATP; however, their coupling of ATP hydrolysis to substrate transport remains elusive.

A Novel Type of Fluorescent Chlorophyll Catabolites Hypermodified by Lipophilic Chloroplast Membrane Components

Helvetica Chimica Acta, EarlyView.
Breakdown of chlorophyll (Chl) is a fundamental biological phenomenon. In de‐greening banana leaves, Chl is transformed into colorless “fluorescent” Chl‐catabolites (FCCs) that cause the leaves to luminesce blue. Hypothesis‐driven search for apolar banana‐FCCs, and structure elucidation, have revealed a striking first link between lipid metabolism and ...

A mitochondrial half-size ABC transporter is involved in cadmium tolerance in Chlamydomonas reinhardtii [PDF]

, 2005
Five cadmium-sensitive insertional mutants, all affected at the CDS1 ('cadmium-sensitive 1') locus, have been previously isolated in the unicellular green alga Chlamydomonas reinhardtii.

Targeting mitochondrial 18 kDa translocator protein (TSPO) regulates macrophage cholesterol efflux and lipid phenotype [PDF]

, 2014
The aim of the present study was to establish mitochondrial cholesterol trafficking 18 kDa translocator protein (TSPO) as a potential therapeutic target, capable of increasing macrophage cholesterol efflux to (apo)lipoprotein acceptors.

Depletion of microglial compensation in glial network: Disease‐associated response dynamics in the revised amyloid hypothesis

Neuroprotection, EarlyView.
The critical transition from amyloid pathology to irreversible neuronal loss in Alzheimer's disease hinges on the microglial response. This review aims to systematize the patterns of how microglia react within the glial context. Abstract Microglia mount coordinated, stage‐dependent compensatory programs in response to early amyloid β (Aβ) accumulation ...

Exploring bat-inspired cyclic tryptophan diketopiperazines as ABCB1 Inhibitors

Communications Chemistry
Chemotherapy-induced drug resistance remains a major cause of cancer recurrence and patient mortality. ATP binding cassette subfamily B member 1 (ABCB1) transporter overexpression in tumors contributes to resistance, yet current ABCB1 inhibitors have ...
