In Vitro Anticancer Effects of Aqueous Leaf Extract from L. ssp. .

Despite significant efforts, cancer remains the second leading cause of mortality worldwide. The medicinal plant L. represents a valuable source of biologically active compounds with pharmacological activities including antioxidant, anti-inflammatory, antimicrobial, and antiviral.

Cytotoxic Effects of Plant Secondary Metabolites and Naturally Occurring Bioactive Peptides on Breast Cancer Model Systems: Molecular Mechanisms.

Breast cancer is the second leading cause of death among women, and the number of mortal cases in diagnosed patients is constantly increasing. The search for new plant compounds with antitumor effects is very important because of the side effects of conventional therapy and the development of drug resistance in cancer cells. The use of plant substances in medicine has been well known for centuries, but the exact mechanism of their action is far from being elucidated.

Molecular mechanisms of the anticancer action of fustin isolated from Scop. in MDA-MB-231 triple-negative breast cancer cell line.

The aim of the present work was to investigate some of the molecular mechanisms and targets of the anticancer action of the bioflavonoid fustin isolated from the heartwood of Scop. in the triple-negative breast cancer cell line MDA-MB-231. For this purpose, we applied fluorescence microscopy analysis to evaluate apoptosis, necrosis, and mitochondrial integrity, wound healing assay to study fustin antimigratory potential and quantitative reverse transcription-polymerase chain reaction to analyze the expression of genes associated with cell cycle control, programmed cell death, metastasis, and epigenetic alterations.

PEGylated Nanographene Oxide in Combination with Near-Infrared Laser Irradiation as a Smart Nanocarrier in Colon Cancer Targeted Therapy.

Anti-cancer therapies that integrate smart nanomaterials are the focus of cancer research in recent years. Here, we present our results with PEGylated nanographene oxide particles (nGO-PEG) and have studied their combined effect with near-infrared (NIR) irradiation on low and high invasive colorectal carcinoma cells. The aim is to develop nGO-PEG as a smart nanocarrier for colon cancer-targeted therapy.

Scop. induces cell cycle arrest, apoptosis, genotoxic effects, thermodynamic and epigenetic events in MCF7 breast cancer cells.

Current plant-derived anticancer therapeutics aim to reach higher effectiveness, to potentiate chemosensitivity and minimize the toxic side effects compared to conventional chemotherapy. Scop. is a herb with high pharmacological potential, widely applied in traditional phytotherapy.

Antiviral, Cytotoxic and Antioxidant Effects of L. Crude Extract In Vitro.

Introduction: Due to the high prevalence of viral infections having no specific treatment and the constant emergence of resistant viral strains, searching for effective antiviral compounds is crucial. The present study explores in vitro the antiviral activity of ethanolic extract from aerial parts of.

Aim: The aim of the current study was to evaluate antiviral activity of ethanolic extract from herbaceous plant.

CHEK2 gene alterations independently increase the risk of death from breast cancer in Bulgarian patients.

Checkpoint kinase 2 (CHEK2) is a DNA damage-activated protein kinase implicated in cell cycle checkpoint control. The significance of CHEK2 alterations for breast cancer incidence and clinical behavior is not clear. In this study we determined the mutational spectrum and the level of promoter hypermethylation of CHEK2 gene in a group of 145 Bulgarian patients with breast cancer.

Breast cancer patients with hypermethylation in the promoter of BRCA1 gene exhibit favorable clinical status.

Promoter hypermethylation was shown to be involved in human cancerogenesis through silencing gene expression. Several studies were dedicated to explore the frequency and clinical significance of BRCA1 hypermethylation in sporadic breast cancer to identify a specific molecular and clinico-pathological phenotype. However the available data are limited and rather too heterogeneous.
