Article Abstract

Jasmonates (JAs) have traditionally been studied for their defensive roles against wounding and detrimental organisms, but they are also crucial hormones for plant-microbe beneficial interactions. Here, we review the most recent advances in this overlooked field. We cover the evolutionary divergences of JA biosynthesis and signalling across various plant lineages and present the molecular mechanisms of action through which beneficial microbes interact with the host JA signalling pathway as well as environmental integration. Special emphasis is given to the cutting-edge tools to study the spatial compartmentalization and cell and tissue specialization of JA signalling. This review underscores the role of the JA signalling pathway, with the MYELOCYTOMATOSIS2 transcription factor as a potential integrator of biotic and environmental cues, and highlights its significance in mutualistic interactions.

Despite significant advancements in the treatment of non-small cell lung cancer (NSCLC) using conventional therapeutic methods, drug resistance remains a major factor contributing to disease recurrence. In this study, we aimed to explore the potential benefits of combining PI3K inhibition with Cisplatin in the context of NSCLC-derived A549 cells. Human non-small cell lung cancer A549 cells were cultured and treated with BKM120, cisplatin, or their combination.

Background: Standard treatment for glioblastoma includes chemotherapy, alkylating agents such as temozolomide (TMZ); however, MGMT resistance leads to recurrence. Demethoxycurcumin (DMC) has been reported to inhibit cancer cell growth, induce apoptosis, and prevent metastasis in different cancer models. We investigated the DMC-induced apoptosis and autophagy via inhibition of the AKT/mTOR pathway in human glioma U87MG and T98G cell lines.

Acute or chronic liver damage can result in Hepatic Encephalopathy (HE), a potentially fatal neuropsychiatric condition that leads to cerebral and neurological alterations. Dapagliflozin (DAPA), an orally active Sodium/Glucose cotransporter 2 inhibitor with long duration of action. The study aim was to evaluate the potential protective impact of DAPA against HE caused by Thioacetamide (TAA) in rats.

Metabolic associated steatohepatitis (MASH) is a severe form of metabolic dysfunction-associated steatotic liver disease (MASLD) characterized by hepatocellular injury, inflammation, and fibrosis. Despite advances in understanding its pathophysiology, the molecular mechanisms driving MASH progression remain unclear. This study investigates the role of long non-coding RNA Linc01271 in MASLD/MASH pathogenesis, ant its involvement in the miR-149-3p/RAB35 axis and PI3K/AKT/mTOR signaling pathway.

Plasmalogens are a subclass of glycerophospholipids characterized by a vinyl-ether bond at the sn-1 position; they play several physiological roles including membrane stabilization, antioxidant activity, and signal transduction. While choline, ethanolamine, serine, and glycerol plasmalogens (PlsCho, PlsEtn, PlsSer, and PlsGro) are naturally abundant, inositol plasmalogens (PlsIns) are rare. In contrast to the limited occurrence of PlsIns, phosphatidylinositol is a biologically crucial lipid, and its enzymatic biosynthesis from phosphatidylcholine has been extensively studied.
