Mesenchymal stem cells (MSCs) have the self-renewal ability and the ability to produce multiple differentiation. Elucidating the genetic circuits that govern MSC self-renewal and differentiation is necessary to improve our comprehension of MSCs and their role in regenerative medicine. microRNAs (miRNAs) play important roles in the regulation of transcription, and are strongly linked with MSCs regarding the maintenance of pluripotency properties. Peroxisome proliferator-activated receptors (PPARs) are ligand-activated transcription factors that belong to the nuclear hormonereceptor family. Interestingly, PPARs not only regulate glucose metabolism and lipidhomeostasis, but also contribute to cell proliferation, cell differentiation, and cell apoptosis. The aim of the present review was to provide an insight into the roles of miRNAs and PPARs in the differentiation of MSCs. Understanding the miRNA signature interactions in conjunction with the role of PPARs is critical for the development of improved strategies to regulate the differentiation of MSCs.

Malignant tumors are among the major diseases threatening human survival in the world, and advancements in medical technology have led to a steady increase in their detection rates worldwide. Despite unique clinical presentations across the spectrum of malignancies, treatment modalities generally adhere to common strategies, encompassing primarily surgical intervention, radiation therapy, chemotherapy, and targeted treatments. Uncovering the genetic elements contributing to cancer cell proliferation, metastasis, and drug resistance remains a pivotal pursuit in the development of novel targeted therapeutics.

Chemotherapy-induced peripheral neuropathy (CIPN) is a serious side effect of anticancer agents with limited effective preventive or therapeutic interventions. Although fenofibrate, a peroxisome proliferator-activated receptor-alpha (PPARα) agonist, has demonstrated neuroprotective and analgesic properties, its clinical utility is hindered by low receptor affinity, poor subtype selectivity, and suboptimal bioavailability. A190, a highly selective and potent nonfibrate PPARα agonist, offers a promising alternative but is limited by poor aqueous solubility, resulting in reduced oral bioavailability and therapeutic efficacy.

Background: Acute systemic inflammation affects many organs and it occurs in a wide range of conditions such as acute lung injury (ALI). Inflammation-triggered oxidative pathways together with the caspase activation seen in ALI, result in apoptosis. Dapagliflozin (DPG) is an agent that is known to have oxidative stress-reducing and anti-inflammatory effects in many tissues.

Quercetin (QE), a particular flavonoid, is well known for its medicinal effects, including anti-oxidant, hypoglycemic, and anti-inflammatory effects. In this review, the findings of QE effects on diabetes STZinduced, alloxan-induced, and its complications have been summarized with a particular focus on in vitro, in vivo, and clinical trials. Consequently, QE mediates several mechanisms, including ameliorating tumor necrosis factor (TNF)-α, nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB), interleukin (IL)-1β, IL-8, and IL-10 expression, increasing insulin glucose uptake to inhibit insulin resistance.
