Olaparib synergy screen reveals Exemestane induces replication stress in triple‐negative breast cancer

open access: yesMolecular Oncology, EarlyView.
Screening 166 FDA‐approved anticancer drugs identifies the aromatase inhibitor Exemestane as a synergistic partner of PARP inhibitor Olaparib in BRCA‐proficient triple‐negative breast cancer. Exemestane induces ROS‐mediated replication stress, enhancing DNA damage and apoptosis alongside Olaparib.

YAP1::TFE3 mediates endothelial‐to‐mesenchymal plasticity in epithelioid hemangioendothelioma

open access: yesMolecular Oncology, EarlyView.
The YAP1::TFE3 fusion protein drives endothelial‐to‐mesenchymal transition (EndMT) plasticity, resulting in the loss of endothelial characteristics and gain of mesenchymal‐like properties, including resistance to anoikis, increased migratory capacity, and loss of contact growth inhibition in endothelial cells.

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

open access: yesАнтибиотики 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.

The tumor–microbe connection

open access: yesMolecular Oncology, EarlyView.
Tumor‐associated bacteria (TAB) dynamically influence cancer biology by modulating tumor progression, metastatic spread, and therapeutic efficacy. Their presence redefines the tumor microenvironment (TME) as a microbial–host interface, yet mechanistic insights remain limited. Understanding TAB colonization routes, functional impacts, and crosstalk with

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

open access: yesАнтибиотики 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.

Antibiotics and Antibiotic Resistance

open access: yesBiomedical Journal of Scientific & Technical Research, 2017
According to the World Health Organization (WHO)’s "First Global Report on Antibiotic Resistance“, and the U.S. Centers for Disease Control & Prevention (CDC&P), the spread of "superbugs“ - bacteria that have changed in ways that render antibiotics ineffective against them - is a serious and growing threat around the world...

Gut microbiota diversity is prognostic in metastatic hormone receptor‐positive breast cancer patients receiving chemotherapy and immunotherapy

open access: yesMolecular Oncology, EarlyView.
In this exploratory study, we investigated the relationship between the gut microbiota and outcome in patients with metastatic hormone receptor‐positive breast cancer, treated in a randomized clinical trial with chemotherapy alone or chemotherapy in combination with immune checkpoint blockade.

Irumamicin Produced by Streptomyces roseoflavus INA-1278

open access: yesАнтибиотики и Химиотерапия, 2020
The strain Streptomyces roseoflavus INA-1278 is described as a new irumamicin producer. Irumamicin 1278 is different by the antifungal activity from irumamicin produced by the world-known strain Streptomyces subflavus subsp. Irumaensis subps. nov.
