induces autophagic and apoptotic cell death in pancreatic cancer cells.

Pancreatic cancer is a leading cause of cancer-related mortality worldwide with increasing global incidence. We previously reported the anticancer effect of ethanolic extract (RCE) in triple negative breast and colon cancer cells. Herein, we investigated the anticancer effect of RCE on human pancreatic cancer cells.

Phytochemical-mediated modulation of autophagy and endoplasmic reticulum stress as a cancer therapeutic approach.

Autophagy and endoplasmic reticulum (ER) stress are conserved processes that generally promote survival, but can induce cell death when physiological thresholds are crossed. The pro-survival aspects of these processes are exploited by cancer cells for tumor development and progression. Therefore, anticancer drugs targeting autophagy or ER stress to induce cell death and/or block the pro-survival aspects are being investigated extensively.

C-peptide in diabetes: A player in a dual hormone disorder?

C-peptide, a byproduct of insulin synthesis believed to be biologically inert, is emerging as a multifunctional molecule. C-peptide serves an anti-inflammatory and anti-atherogenic role in type 1 diabetes mellitus (T1DM) and early T2DM. C-peptide protects endothelial cells by activating AMP-activated protein kinase α, thus suppressing the activity of NAD(P)H oxidase activity and reducing reactive oxygen species (ROS) generation.

Targeting Triple-Negative Breast Cancer by the Phytopolyphenol Carnosol: ROS-Dependent Mechanisms.

Triple-negative breast cancer (TNBC), which lacks the expression of the three hormone receptors (i.e., estrogen receptor, progesterone receptor, and human epidermal growth factor receptor), is characterized by a high proliferative index, high invasiveness, poor prognosis, early relapse, and a tendency to be present in advanced stages.

Oxidative Stress Inducers in Cancer Therapy: Preclinical and Clinical Evidence.

Reactive oxygen species (ROS) are metabolic byproducts that regulate various cellular processes. However, at high levels, ROS induce oxidative stress, which in turn can trigger cell death. Cancer cells alter the redox homeostasis to facilitate protumorigenic processes; however, this leaves them vulnerable to further increases in ROS levels.

Synthesis of New Chromene Derivatives Targeting Triple-Negative Breast Cancer Cells.

Breast cancer continues to be the leading cause of cancer-related deaths among women worldwide. The most aggressive type of breast cancer is triple-negative breast cancer (TNBC). Indeed, not only does TNBC not respond well to several chemotherapeutic agents, but it also frequently develops resistance to various anti-cancer drugs, including taxane mitotic inhibitors.

Immunotherapy and immunoevasion of colorectal cancer.

The tremendous success of immunotherapy in clinical trials has led to its establishment as a new pillar of cancer therapy.

Here, we discuss the molecular and genetic heterogeneity of CRC.

Therapeutic Potential of Decoys for Prostate Cancers: A Review of Recent Updates.

Prostate cancer is ranked second among the most common male cancers. Androgen deprivation therapy (ADT) has long been the first-line treatment and the basis for all other therapies, reducing circulating androgens to castration levels and preventing disease development. Nevertheless, ADT monotherapy may not always limit disease development, and even at low testosterone levels, hormone-sensitive prostate cancer will become castration-resistant.

The SARS-CoV-2 Spike Protein Activates the Epidermal Growth Factor Receptor-Mediated Signaling.

The coronavirus disease-19 (COVID-19) pandemic is caused by the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). At the molecular and cellular levels, the SARS-CoV-2 uses its envelope glycoprotein, the spike S protein, to infect the target cells in the lungs via binding with their transmembrane receptor, the angiotensin-converting enzyme 2 (ACE2). Here, we wanted to investigate if other molecular targets and pathways may be used by SARS-CoV-2.

Propolis: A Detailed Insight of Its Anticancer Molecular Mechanisms.

Cancer is the second most life-threatening disease and has become a global health and economic problem worldwide.

The current therapeutic strategies for cancer lack the efficacy due to the emergence of drug resistance and the toxic side effects associated with the treatment.

Effect of Resveratrol on Pregnancy, Prenatal Complications and Pregnancy-Associated Structure Alterations.

Adverse pregnancy outcomes are considered significant health risks for pregnant women and their offspring during pregnancy and throughout their lifespan. These outcomes lead to a perturbated in-utero environment that impacts critical phases of the fetus's life and correlates to an increased risk of chronic pathological conditions, such as diabetes, obesity, and cardiovascular diseases, in both the mother's and adult offspring's life. The dietary intake of naturally occurring antioxidants promotes health benefits and disease prevention.

2-Nucleobase-substituted 4,6-Diaminotriazine Analogs: Synthesis and Anti-cancer Activity in 5-Fluorouracil-sensitive and Resistant Colorectal Cancer Cells.

Background: Cancer continues to be the second leading cause of death worldwide, with colorectal cancer (CRC) being the third most common type. Despite significant advances in cancer therapies, the current treatment of CRC remains suboptimal. In addition, the effectiveness of available chemotherapeutic drugs such as 5-Fluorouracil (5-FU) is limited by CRC-acquired resistance.
