Comprehensive antigenotoxic profile of endemic Petrak extracts against hydrogen peroxide induced toxicity.

Cyto/genotoxicity have been widespread utilized for the safety risk assessment of synthetic/natural chemicals. Plants can protect organisms from harmful effects of xenobiotics. On the other hand, plants can extract toxic molecules from the environment which may disrupt mitosis and cytokinesis.

Plants from Northwestern Anatolia Display Selective Cytotoxicity and Induce Mitotic Catastrophe: A Study on Anticancer and Genotoxic Activities.

Anatolia is rich in floristic diversity with a high rate of endemism. Eight plant species from northwestern Anatolia were evaluated for their anti-growth properties in two malignant (MCF-7 and MDA-MB-231) and a non-malignant (MCF-10A) breast cell lines. The two most active extracts, Achillea multifida (AME) and Astragalus sibthorpianus (ASE), induced apoptotic cell death in all cell lines.

Simultaneous inhibition of PFKFB3 and GLS1 selectively kills KRAS-transformed pancreatic cells.

Activating mutations of the oncogenic KRAS in pancreatic ductal adenocarcinoma (PDAC) are associated with an aberrant metabolic phenotype that may be therapeutically exploited. Increased glutamine utilization via glutaminase-1 (GLS1) is one such feature of the activated KRAS signaling that is essential to cell survival and proliferation; however, metabolic plasticity of PDAC cells allow them to adapt to GLS1 inhibition via various mechanisms including activation of glycolysis, suggesting a requirement for combinatorial anti-metabolic approaches to combat PDAC. We investigated whether targeting the glycolytic regulator 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase-3 (PFKFB3) in combination with GLS1 can selectively prevent the growth of KRAS-transformed cells.

Palladium (II) Complex Enhances ROS-Dependent Apoptotic Effects via Autophagy Inhibition and Disruption of Multiple Signaling Pathways in Colorectal Cancer Cells.

Background: Inhibition of autophagy is reported to be a therapeutically effective strategy in overcoming resistance that is a deadly outcome in cancer. One of the most common reasons for chemo-resistance to treatment is the patients with tumors exhibiting a KRAS mutation, which occurs in approximately 40% of colorectal cancer patients.

Objective: Hence, we assessed whether a Palladium (Pd)(II) complex is a promising anticancer complex, compared to 5-fluorouracil in KRAS wt HT-29 and KRAS mutant HCT-15 cells.

A promising therapeutic combination for metastatic prostate cancer: Chloroquine as autophagy inhibitor and palladium(II) barbiturate complex.

Autophagy is a catabolic process for cells that can provide energy sources and allows cancer cells to evade cell death. Therefore, studies on the combination of autophagy inhibitors with drugs are increasing as a new treatment modality in cancer. Previously, we reported the anti-tumor activity of a Palladium (Pd)(II) complex against different types of cancer in vitro and in vivo.
