Abstract Background Obesity confers increased risk for various types of cancer. PD-L1 is a key molecule in tumor immune evasion by inducing T cell exhaustion. The relationship between obesity and still ambiguous. This study was designed to reveal the development hepatocellular carcinoma melanoma obese mice investigate if adipocytes regulate expression underlying mechanism. Methods Monosodium glutamate-induced were inoculated with H22 cells High fat diet (HFD)-induced B16-F1 mouse cells. Human hepatoma HepG2 treated conditional media from 3T3-L1 (adi-CM). Neutralized anti-TNF-α anti-IL-6 antibodies inhibitor NF-κB or STAT3 used mechanism effect adi-CM. Results In mice, tissues grew faster tissue increased. Adi-CM up-regulated level vitro. Differentiated secreted TNF-α IL-6, neutralizing and/or IL-6 reduced adi-CM-treated p-NF-κB/NF-κB downregulated cells, p-STAT3/STAT3 also decreased addition, reversed adi-CM on expression.

The prevalence of cardiovascular disease (CVD) is increasing over time. CVD a comorbidity in diabetes and contributes to premature death. Citrus flavonoids possess several biological activities have emerged as efficient therapeutics for the treatment CVD. scavenge free radicals, improve glucose tolerance insulin sensitivity, modulate lipid metabolism adipocyte differentiation, suppress inflammation apoptosis, endothelial dysfunction. intake citrus has been associated with improved outcomes. Although exerted multiple beneficial effects, their mechanisms action are not completely established. In this review, we summarized recent findings advances understanding underlying protective effects against oxidative stress, inflammation, diabetes, dyslipidemia, dysfunction, atherosclerosis. Further studies clinical trials assess efficacy explore mechanism(s) recommended.

Metabolic syndrome (MetS) is a complex of diseases that lead to mortality due the development cardiovascular problems. Quercetin, as an important flavonoid, has various properties such decreasing blood pressure, anti‐hyperlipidemia, anti‐hyperglycemia, anti‐oxidant, antiviral, anticancer, anti‐inflammatory, anti‐microbial, neuroprotective, and cardio‐protective effects. In this review article, we collected original articles from different sources Google Scholar, Medline, Scopus, Pubmed, which related effect quercetin on improvement signs MetS, including elevated glucose level, hyperlipidemia, obesity, pressure. According these data, may also have role in management metabolic disorders via mechanisms increasing adiponectin, leptin, anti‐oxidant activity, reduction insulin resistance, elevation blocking calcium channel.

Among subjects, 14 subjects underwent laparoscopic sleeve gastrectomy (LSG) were followed 6 months after surgery. Abdominal area (VFA) subcutaneous (SFA) measured by magnetic resonance imaging. Waist, hipline, waist-to-hip ratio (WHR) body mass index (BMI) included as simple parameters. Gut was analyzed metagenomic sequencing.Among parameters, VFA had largest number of correlations with species that differentially enriched following waist, WHR, BMI, SFA. Within negatively correlated VFA, Eubacterium eligens strongest correlation, Clostridium citroniae, C. symbiosum, Bacteroides uniformis, E. ventriosum, Ruminococcaceae bacterium D16, hathewayi, etc. hathewayi citroniae increased LSG. Functional analyses showed among all correlation coefficients obesity-related microbial pathways.

Monosodium glutamate (MSG) is one of the most popular food additives in world and often ingested with commercially processed foods. It can be described as a sodium salt glutamic acid IUPAC name - Sodium 2-aminopentanedioate ionized by water to produce free ions acid. MSG use has significantly increased over past 30 years, its global demand stands huge at three million metric tons which worth $4.5 billion. Asia was responsible for more than quarter consumption country China also leading well production export other countries. Prior year 2020, almost four percent each highest significant increase predicted rise Thailand, Indonesia, Vietnam China, followed Brazil Nigeria. However, several researches featured this review identified major contributor development progression some metabolic disorders such obesity, risk factor syndromes like hypertension, diabetes mellitus cancer initiation. The mechanism induce obesity involves induction hypothalamic lesion, hyperlipidemia, oxidative stress, leptin resistance expression peroxisome proliferator-activated receptors (PPARs) Gamma Alpha. Similarly mellitus, resulted decreased pancreatic beta cell mass, stress rates, reduced glucose insulin transport adipose tissue skeletal muscles, insensitivity, induced severe hyperinsulinemia.
