Morphine counteracts the effects of paclitaxel in triple-negative breast cancer cells.

Background & Objectives: Several studies have provided evidence that opioids may play a role in cancer recurrence and metastasis. Multiple research data indicate that morphine can act as a proliferative or suppressive agent on tumour cells depending on the applied concentration. Therefore, this study was aimed to investigate whether the presence of clinically relevant concentrations of morphine has any effect on the efficacy of paclitaxel, a widely used chemotherapeutic drug, on the viability and apoptosis of human triple-negative breast cancer cell line.

Inhibition of Plasma Membrane Calcium Pump Influences Intracellular Calcium Signaling Pathways in Breast Cancer.

The plasma membrane calcium pump (PMCA) is an important transporter that maintains intracellular calcium concentration ([Ca]). It allows the calcium (Ca) from inside the cell to go out of the cell through the plasma membrane. For this, it cooperates with the proteins in the cell.

Transgenerational impact of topical steroid application on superoxide dismutase activities of hypothalamus-pituitary-adrenal axis in rats.

Topical steroids (TS) have been widely prescribed since the 1950s. This study investigated for the first time the transgenerational effects of TS on the antioxidant mechanism of the hypothalamus-pituitary-adrenal (HPA) axis, both in prenatal and infancy. Three generations (F1, F2, and F3) and prenatal group (P) were investigated in both sexes with two different time points; P45th and P75th day were accepted as puberty and early adulthood, respectively.

The Effect of Cyclosporine A on Proteins Controlling Intracellular Calcium Concentration in Breast Cancer Cells.

Cyclosporine A (CsA) is an immunosuppressive drug commonly used to prevent autoimmune diseases. At the same time, CsA is a calcineurin (CaN) inhibitor. It affects the intracellular calcium signaling pathway.

The effect of bee bread (Perga) with chemotherapy on MDA-MB-231 cells.

Bee bread (BB) is a bee product like propolis and honey. It is the main food for larvae and bees producing royal jelly in the hive. It also known as Perga.

Prevalence of Microsporidiosis in Different Hosts in Turkey: A Meta-analysis.

Objective: Microsporidia are opportunistic obligate intracellular pathogens which infect many vertebrate and invertebrate hosts. This study aimed at investigating all evidence about microsporidia infection in human and other vertebrate hosts in Turkey.

Methods: This study covered all prevalence studies, related to microsporidiosis in Turkey until April 2020, that were found in Web of Science, PubMed, Scopus, and ULAKBIM databases were considered in this meta-analysis.

Encephalitozoon intestinalis Infection Impacts the Expression of Apoptosis-Related Genes in U937 Macrophage Cells.

Purpose: Encephalitozoon intestinalis affects many physiological processes of host cells to survive, proliferate, and spread to different regions within the body. In this study, the effects of the parasite on host cell apoptosis and proliferation were investigated.

Methods: To determine the impact of the parasite on the host cell apoptosis, changes in the expression profile of genes were investigated with the qPCR array using the Human Apoptosis Panel in infected and non-infected macrophage cells.
