Patient‐specific pharmacogenomics demonstrates xCT as predictive therapeutic target in colon cancer with possible implications in tumor connectivity

Molecular Oncology, EarlyView.
This study integrates transcriptomic profiling of matched tumor and healthy tissues from 32 colorectal cancer patients with functional validation in patient‐derived organoids, revealing dysregulated metabolic programs driven by overexpressed xCT (SLC7A11) and SLC3A2, identifying an oncogenic cystine/glutamate transporter signature linked to ...

Antimicrobial Activity of Microorganisms Isolated from the Soil of the Tropical Desert of the Sinai Peninsula

Антибиотики и Химиотерапия
Background. The spread of pathogenic antibiotic-resistant microorganisms often leads to the inefficiency of antimicrobial therapy. One of the solutions to this problem is the search for new active natural antibiotics.The aim of the study.

Parents' beliefs and knowledge about the management of acute otitis media: A qualitative study [PDF]

, 2015
BACKGROUND: Acute otitis media is a common reason for antibiotic prescribing, despite strong evidence that antibiotics provide minimal benefit. Studies have demonstrated that patients’ (or parents’) expectations of antibiotics often influence general ...

Survivin and Aurora Kinase A control cell fate decisions during mitosis

Molecular Oncology, EarlyView.
Aurora A interacts with survivin during mitosis and regulates its centromeric role. Loss of Aurora A activity mislocalises survivin, the CPC and BubR1, leading to disruption of the spindle checkpoint and triggering premature mitotic exit, which we refer to as ‘mitotic slippage’.

Pharmacokinetics of Olivamide after Bolus Administration in Rats and Rabbits (a Pilot Study)

Антибиотики и Химиотерапия, 2020
The pharmacokinetics of olivamide, a semisynthetic antitumor derivate of olivomycin A, were studied in rats and rabbits after bolus administration. Plasma concentrations of olivamide were determined by an HPLC assay.

CDK11 inhibition induces cytoplasmic p21WAF1 splice variant by p53 stabilisation and SF3B1 inactivation

Molecular Oncology, EarlyView.
CDK11 inhibition stabilises the tumour suppressor p53 and triggers the production of an alternative p21WAF1 splice variant p21L, through the inactivation of the spliceosomal protein SF3B1. Unlike the canonical p21WAF1 protein, p21L is localised in the cytoplasm and has reduced cell cycle‐blocking activity.

Cell surface interactome analysis identifies TSPAN4 as a negative regulator of PD‐L1 in melanoma

Molecular Oncology, EarlyView.
Using cell surface proximity biotinylation, we identified tetraspanin TSPAN4 within the PD‐L1 interactome of melanoma cells. TSPAN4 negatively regulates PD‐L1 expression and lateral mobility by limiting its interaction with CMTM6 and promoting PD‐L1 degradation.

Effect of β-lactamase inhibitors on in vitro activity of β-lactam antibiotics against Burkholderia cepacia complex species [PDF]

, 2016
Background: Bacteria belonging to the Burkholderia cepacia complex (Bcc) are an important cause of chronic respiratory tract infections in cystic fibrosis patients. Intrinsic resistance to a wide range of antimicrobial agents, including a variety of beta-

Recurrent cancer‐associated ERBB4 mutations are transforming and confer resistance to targeted therapies

Molecular Oncology, EarlyView.
We show that the majority of the 18 analyzed recurrent cancer‐associated ERBB4 mutations are transforming. The most potent mutations are activating, co‐operate with other ERBB receptors, and are sensitive to pan‐ERBB inhibitors. Activating ERBB4 mutations also promote therapy resistance in EGFR‐mutant lung cancer.
