MicroRNA-721 regulates gluconeogenesis via KDM2A-mediated epigenetic modulation in diet-induced insulin resistance in C57BL/6J mice.

Background: Aberrant gluconeogenesis is considered among primary drivers of hyperglycemia under insulin resistant conditions, with multiple studies pointing towards epigenetic dysregulation. Here we examine the role of miR-721 and effect of epigenetic modulator laccaic acid on the regulation of gluconeogenesis under high fat diet induced insulin resistance.

Results: Reanalysis of miRNA profiling data of high-fat diet-induced insulin-resistant mice model, GEO dataset (GSE94799) revealed a significant upregulation of miR-721, which was further validated in invivo insulin resistance in mice and invitro insulin resistance in Hepa 1-6 cells.

L-Methionine accentuates anti-tumor action of Gefitinib in Gefitinib-resistant lung adenocarcinoma: Role of EGFR/ERK/AKT signaling and histone H3K36me2 alteration.

Adenocarcinoma, the predominant subtype of non-small cell lung cancer (NSCLC), poses a significant clinical challenge due to its prevalence and aggressive nature. Gefitinib, an epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor is often susceptible to development of resistance despite being the preferred treatment option for NSCLC. In this study, we investigated the potential of L-Methionine in enhancing the cytotoxicity of Gefitinib and preventing resistance development.

l-Methionine potentiates anticancer activity of Sorafenib by epigenetically altering DUSP3/ERK pathway in hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) is the third most common cancer-related cause of death worldwide. Although Sorafenib is the standard systemic therapy for treating HCC, but it develops resistance very quickly, leading to poor prognosis. The current study was planned to explore the effect of l-methionine on the anticancer activity of Sorafenib in HCC.

Pharmacological inhibition of DNMT1 restores macrophage autophagy and M2 polarization in Western diet-induced nonalcoholic fatty liver disease.

Nonalcoholic fatty liver disease (NAFLD) is associated with an increased ratio of classically activated M1 macrophages/Kupffer cells to alternatively activated M2 macrophages, which plays an imperative role in the development and progression of NAFLD. However, little is known about the precise mechanism behind macrophage polarization shift. Here, we provide evidence regarding the relationship between the polarization shift in Kupffer cells and autophagy resulting from lipid exposure.

Laccaic acid restores epigenetic alterations responsible for high fat diet induced insulin resistance in C57BL/6J mice.

Laccaic acid, the major constituent of the food colouring agent-lac dye, possesses antioxidant and anti-inflammatory properties. Here we have evaluated the effects of laccaic acid on the high-fat diet induced insulin resistance in C57BL/6J mice. Insulin resistance was developed in mice by feeding high-fat diet for 12 weeks.

Cisplatin conjugation with an exopolysaccharide extracted from Lactobacillus gasseri potentiates its efficacy and attenuates its toxicity.

The development of newer cisplatin analogs is constantly being investigated owing to its low solubility, poor pharmacokinetics, and dose-related toxicity. In order to address the limitations of current cisplatin therapy, the present study was undertaken. Cisplatin conjugation with an exopolysaccharide extracted from Lactobacillus gasseri (LG-EPS) showed remarkably enhanced and selective anticancer activity by targeting tumor cells overexpressing glucose transporter 1 (GLUT1).

Lactobacillus rhamnosus supplementation ameliorates high fat diet-induced epigenetic alterations and prevents its intergenerational inheritance.

Aim: Multiple studies have reported the epigenetic inheritance of parental metabolic traits could increase the risk of developing metabolic disorders in offsprings. L. rhamnosus (LR) as a probiotic has been found to be beneficial in metabolic diseases.

Nanocrystal-based gel of apremilast ameliorates imiquimod-induced psoriasis by suppressing inflammatory responses.

Apremilast is 'difficult-to-deliver' in stratum corneum and viable layers (viable epidermis, dermis) owing to its modest lipophilicity and poor aqueous solubility, respectively. The objective of the present research was to develop apremilast nanocrystal-based gel for enhanced anti-psoriatic efficacy for the treatment of psoriasis. Nanosuspension was generated by wet media milling with a mean particle size of 200 nm.

Selenium-Enriched Probiotic Alleviates Western Diet-Induced Non-alcoholic Fatty Liver Disease in Rats via Modulation of Autophagy Through AMPK/SIRT-1 Pathway.

Current study was aimed to investigate the ability of L.acidophilus SNZ 86 to biotransform inorganic selenium to a more active organic form, resulting in trace element enrichment. Selenium-enriched L.

AdipoRon: A Novel Insulin Sensitizer in Various Complications and the Underlying Mechanisms: A Review.

Background: AdipoRon is the first synthetic analog of endogenous adiponectin, an adipose tissue-derived hormone. AdipoRon possesses pharmacological properties similar to adiponectin and its ability to bind and activate the adipoR1 and adipoR2 receptors makes it a suitable candidate for the treatment of a multitude of disorders.

Objective: In the present review, an attempt was made to compile and discuss the efficacy of adipoRon against various disorders.

Dietary Supplementation of Methyl Donor l-Methionine Alters Epigenetic Modification in Type 2 Diabetes.

Scope: The aim of the current study is to evaluate whether l-methionine supplementation (l-Met-S) improves type 2 diabetes-induced alterations in glucose and lipid metabolism by modulating one-carbon metabolism and methylation status.

Methods And Results: Diabetes is induced in male Sprague-Dawley rats using high-fat diet and low dose streptozotocin. At the end of study, various biochemical parameters, immunoblotting, qRT-PCR and ChIP-qPCR are performed.
