Involvement of the Opioid Peptide Family in Cancer Progression.

Peptides mediate cancer progression favoring the mitogenesis, migration, and invasion of tumor cells, promoting metastasis and anti-apoptotic mechanisms, and facilitating angiogenesis/lymphangiogenesis. Tumor cells overexpress peptide receptors, crucial targets for developing specific treatments against cancer cells using peptide receptor antagonists and promoting apoptosis in tumor cells. Opioids exert an antitumoral effect, whereas others promote tumor growth and metastasis. This review updates the findings regarding the involvement of opioid peptides (enkephalins, endorphins, and dynorphins

Dynamic Evolution of the Tumor Immune Microenvironment in Malignant Tumors and Emerging Therapeutic Paradigms.

Cancer is more than just a collection of tumor cells. The complex tumor system, including the tumor immune microenvironment (TIME), is continually changing. Tumor cells are in constant communication with all stromal elements (e.g., fibroblasts, endothelial cells, and extracellular matrix) and immune effector cells (e.g., T cells, B cells, natural killer cells, dendritic cells, macrophages, and myeloid-derived suppressor cells). Together, these intricate interactions among cell and molecular signaling pathways collectively drive tumor growth, tumor invasion, and metastasis and significantly aff

In particular, an effort has been made to emphasize on the most notable volatile EOs such as thymol, eugenol, limonene, β-caryophyllene, and their interaction with oncogenic signaling pathways (NF-κB,

Processes and therapeutic perspectives of acylation modifications of lysine and cysteine in tumors.

Acylation modification plays a crucial role in tumor progression through altering protein homeostasis and localization. However, a comprehensive summary of these processes is lacking. Protein acylation modifications are comprehensively summarized and categorized based on the amino acids that are modified. This review focuses on modifications of the lysine (acetylation, succinylation, crotonylation, malonylation, and glutarylation) and cysteine (myristoylation and palmitoylation) groups. The key enzymes involved in the occurrence and erasure of different modifications, as well as their effects

Obesity: pathophysiology and therapeutic interventions.

Over the past few decades, obesity has transitioned from a localized health concern to a pressing global public health crisis affecting over 650 million adults globally, as documented by WHO epidemiological surveys. As a chronic metabolic disorder characterized by pathological adipose tissue expansion, chronic inflammation, and neuroendocrine dysregulation that disrupts systemic homeostasis and impairs physiological functions, obesity is rarely an isolated condition; rather, it is frequently complicated by severe comorbidities that collectively elevate mortality risks. Despite advances in nutr
