Recent studies have elucidated that fatty acyl chains, under the enzymatic action of lyso‑phosphatidyl‑choline acyltransferases (LPCATs), expedite incorporation into the sn‑2 site of phosphatidyl‑choline (PC), profoundly affecting pathophysiology. Accumulating evidence suggests that alterations in LPCAT activity are implicated in various diseases, including non‑alcoholic fatty liver disease (NAFLD), hepatitis C, atherosclerosis and cancer. Specifically, LPCAT3 is instrumental in maintaining systemic lipid homeostasis through its roles in hepatic lipogenesis, intestinal lipid absorption and lipoprotein secretion. The liver X receptor (LXR), pivotal in lipid homeostasis, modulates cholesterol, fatty acid (FA) and PL metabolism. LXR's capacity to modify PL composition in response to cellular sterol fluctuations is a vital mechanism for protecting biofilms against lipid stress. Concurrently, LXR activation enhances LPCAT3 expression on cell membranes and elevates polyunsaturated PL levels. This activation can ameliorate saturated free FA effects <i>in vitro</i> or endoplasmic reticulum stress <i>in vivo</i> due to lipid accumulation in hepatic cells. Pharmacological interventions targeting LXR, LPCAT and membrane PL components could offer novel therapeutic directions for NAFLD management.

In the present study, immunohistochemistry revealed that elevated cytoplasmic SETDB1 was correlated with lymph node metastasis and more aggressive breast cancer subtypes. Functionally, wound healing and Transwell assays showed that cytoplasmic SETDB1 is key for cell migration and invasion, as well as induction of epithelial‑mesenchymal transition (EMT), which was reversed by leptomycin B (LMB, a CMR1 inhibitor) treatment. Furthermore, RNA‑seq and metabolite detection revealed that cytoplasmic SETDB1 was associated with metabolism pathway and elevated levels of metabolites involved in the Warburg effect, including glucose, pyruvate, lactate and ATP. Immunoblotting and reverse transcription‑quantitative PCR verified that elevation of cytoplasmic SETDB1 contributed to elevation of c‑MYC expression and subsequent upregulation of lactate dehydrogenase A (LDHA) expression. Notably, gain‑ and loss‑of‑function approaches revealed that LDHA overexpression in T47D cells enhanced migration and invasion by inducing EMT, while its depletion in SETDB1‑overexpressing MCF7 cells reversed SETDB1‑induced migration and invasion, as well as the Warburg effect and EMT.

Dasatinib (5 mg/kg) and quercetin (50 mg/kg) were administered to diabetic db/db mice by gavage for 20 weeks. Body weight, urine albumin‑creatinine ratio (ACR), serum creatinine (Scr), and blood urea nitrogen (BUN) were recorded at the indicated time periods. Periodic acid‑Schiff and Masson's staining were performed to assess the histopathological changes of kidney tissues. Immunohistochemical analysis, immunofluorescence and western blotting were performed to evaluate the expression levels of extracellular matrix (ECM) proteins, autophagic and podocyte differentiation‑related proteins. In addition, mouse podocytes were administered with high‑glucose, DQ and 3‑methyladenine (3‑MA), and the expression levels of autophagic and podocyte differentiation‑related proteins were measured. Moreover, following overexpression of the Notch intracellular domain (NICD), the expression levels of NICD, autophagic and podocyte differentiation‑related proteins were further assessed. DQ significantly reduced the body weight, blood glucose, ACR, Scr and BUN levels and improved the histopathological changes induced in diabetic db/db mice. In addition, DQ caused a significant downregulation of the expression levels of the ECM proteins, improved autophagy and induced an upregulation of the expression levels of podocyte differentiation‑related proteins.

Exosomes derived from adipose‑derived stem cells (ADSC‑Exos) have been explored as an appealing nanodrug delivery system in the treatment of diabetic wounds. However, the short half‑life and low utilization efficiency of exosomes limit their therapeutic effects. Low‑intensity pulsed ultrasound (LIPUS) provides a non‑invasive mechanical stimulus to cells and exerts a number of biological effects such as cavitation and thermal effects. In the present study, whether LIPUS could enhance ADSC‑Exo‑mediated diabetic wound repair was investigated and its possible mechanism of action was explored. After isolation and characterization, ADSC‑Exos were injected into mice with diabetic wounds, then the mice were exposed to LIPUS irradiation. The control mice were subcutaneously injected with PBS. Wound healing assays, laser Doppler perfusion, Masson's staining and angiogenesis assays were used to assess treatment efficiency. Then, ADSC‑Exos were cocultured with human umbilical vein endothelial cells (HUVECs), and the proliferation, migration and tube formation of HUVECs were assessed. Moreover, the cellular uptake of ADSC‑Exos <i>in</i> <i>vitro</i> and <i>in</i> <i>vivo</i> was assessed to explore the synergistic mechanisms underlying the effects of LIPUS.
