Methyl jasmonate: putative mechanisms of action on cancer cells cycle, metabolism, and apoptosis.

Methyl jasmonate (MJ), an oxylipid that induces defense-related mechanisms in plants, has been shown to be active against cancer cells both in vitro and in vivo, without affecting normal cells. Here we review most of the described MJ activities in an attempt to get an integrated view and better understanding of its multifaceted modes of action. MJ (1) arrests cell cycle, inhibiting cell growth and proliferation, (2) causes cell death through the intrinsic/extrinsic proapoptotic, p53-independent apoptotic, and nonapoptotic (necrosis) pathways, (3) detaches hexokinase from the voltage-dependent

Navigating the landscape of protein folding and proteostasis: from molecular chaperones to therapeutic innovations.

Protein folding is a fundamental process ensuring that polypeptide chains acquire the correct three-dimensional structures required for biological function. This complex journey from nascent polypeptides to mature proteins is tightly regulated by the cellular proteostasis network-an integrated system of molecular chaperones, folding enzymes, and degradation machineries. Disruptions in this network lead to dysproteostasis, a pathological state implicated in a growing list of human diseases, including neurodegenerative disorders, metabolic syndromes, and cancer. In this review, we provide a comp

Curcumin as a promising therapeutic agent for diabetic neuropathy: from molecular mechanisms to functional recovery.

Diabetes mellitus is an endocrine disorder characterized by prolonged hyperglycemia. It results from either insulin deficiency (type 1 diabetes mellitus, T1DM) or insulin resistance (type 2 diabetes mellitus, T2DM). This condition has emerged as a significant health concern in recent years. Hyperglycemia induces the overproduction of reactive oxygen species (ROS), which can modulate multiple pathways, including AGEs-RAGE, PKC stimulation, NF-κB and PI3K/AKT. These pathways contribute to diabetes-related complications such as inflammation, oxidative stress, insulin resistance, and reduced gluco

Nanotechnology and Matrix Metalloproteinases in Cancer Diagnosis and Treatment.

Cancer is still one of the leading causes of death worldwide. This great mortality is due to its late diagnosis when the disease is already at advanced stages. Although the efforts made to develop more effective treatments, around 90% of cancer deaths are due to metastasis that confers a systemic character to the disease. Likewise, matrix metalloproteinases (MMPs) are endopeptidases that participate in all the events of the metastatic process. MMPs' augmented concentrations and an increased enzymatic activity have been considered bad prognosis markers of the disease. Therefore, synthetic inhib
