Emerging insights: miRNA modulation of ferroptosis pathways in lung cancer.

The newly discovered programmed iron-dependent necrosis, ferroptosis, is a novel pathway that is controlled by iron-dependent lipid peroxidation and cellular redox changes. It can be triggered intrinsically by low antioxidant enzyme activity or extrinsically by blocking amino acid transporters or activating iron transporters. The induction of ferroptosis involves the activation of specific proteins, suppression of transporters, and increased endoplasmic reticulum (ER) stress (a condition in which the ER, a crucial organelle involved in protein folding and processing, becomes overwhelmed by an accumulation of misfolded or unfolded proteins.

Mitochondrial remodeling in colorectal cancer initiation, progression, metastasis, and therapy: A review.

Colorectal cancer (CRC) is a major health concern with multifactorial pathophysiology representing intense therapeutic challenges. It is well known that deregulation of spatiotemporally-controlled signaling pathways and their metabolic reprogramming effects play a pivotal role in the development and progression of CRC. As such, the mitochondrial role in CRC initiation gained a lot of attention recently, as it is considered the powerhouse that regulates the bioenergetics in CRC.

The role of miRNAs in laryngeal cancer pathogenesis and therapeutic resistance - A focus on signaling pathways interplay.

Laryngeal cancer (LC)is the malignancy of the larynx (voice box). The majority of LC are squamous cell carcinomas. Many risk factors were reported to be associated with LC as tobacco use, obesity, alcohol intake, human papillomavirus (HPV) infection, and asbestos exposure.

Design, synthesis, anticancer evaluation, and ADMET analysis of novel thalidomide analogs as promising immunomodulatory agents.

Immunomodulatory medications like thalidomide and its analogs prevent the production of some proinflammatory cytokines linked to cancer. A new series of thalidomide analogs were designed and synthesized in order to develop potential antitumor immunomodulatory agents. The antiproliferative activities of the new candidates against a panel of three human cancer cell lines (HepG-2, PC3 and MCF-7) were assessed in comparison to thalidomide as a positive control.

Cholesterol-Based Nanovesicles Enhance the In Vitro Cytotoxicity, Ex Vivo Intestinal Absorption, and In Vivo Bioavailability of Flutamide.
