Unlabelled: Numerous studies have investigated the association between obesity and prostate cancer (CaP), although the results have not been concluding due to the great difficulty to evaluate the effects of obesity on the development of this type of tumor. The aim of this study was to carry out a comprehensive over-view of the existing evidence about the role of adipose tissue in the prostate carcinogenesis. Recent evidence suggests that androgens, leptin, IL-6, VEGF, insulin and IGF-1 may play a role in PC progression, while adiponectin and IGFBP-3 may act as "anti-prostatic cancer" adipokines. The potential mechanisms by which obesity may initiate, promote or facilitate the progression of CaP are low levels of testosterone and high levels of estrogen, coexisting metabolic syndrome, increased secretion of leptin, VEGF, IL-6 and TNF-alpha and decreased adiponectin, and excessive intake of saturated fat.

Conclusion: Obesity may promote the progression of established PC rather than being a risk factor for the development of this tumour. However, additional studies are needed to clarify the relationship between adipokines and PC before developing new preventive or treatment strategies for this tumor.

Prognostic impact of subcutaneous fat quality and sarcopenia on the survival outcomes in patients with colorectal cancer.

Purpose: This study aimed to evaluate the relationship between the quantity and quality of subcutaneous fat and prognosis following colorectal cancer resection.

Method: We conducted a retrospective analysis of the clinical data of 399 patients who underwent curative resection for stage 2 or 3 colorectal cancer between January 2013 and March 2019. This study examined the correlation between sarcopenia and various fat parameters, including fat area and density, and assessed their impact on the prognosis.

Identification of a distal enhancer of Ucp1 essential for thermogenesis and mitochondrial function in brown fat.

Uncoupling protein 1 (UCP1) is a crucial protein located in the mitochondrial inner membrane that mediates nonshivering thermogenesis. However, the molecular mechanisms by which enhancer-promoter chromatin interactions control Ucp1 transcriptional regulation in brown adipose tissue (BAT) are unclear. Here, we employed circularized chromosome conformation capture coupled with next-generation sequencing (4C-seq) to generate high-resolution chromatin interaction profiles of Ucp1 in interscapular brown adipose tissue (iBAT) and epididymal white adipose tissue (eWAT) and revealed marked changes in Ucp1 chromatin interaction between iBAT and eWAT.

Divergent roles of mA in orchestrating brown and white adipocyte transcriptomes and systemic metabolism.

N-methyladenosine (mA) is among the most abundant mRNA modifications, yet its cell-type-specific regulatory roles remain unclear. Here we show that mA methyltransferase-like 14 (METTL14) differentially regulates transcriptome in brown versus white adipose tissue (BAT and WAT), leading to divergent metabolic outcomes. In humans and mice with insulin resistance, METTL14 expression differs significantly from BAT and WAT in the context of its correlation with insulin sensitivity.

Corticosteroid binding globulin (CBG; SERPINA6) binds >85% of circulating glucocorticoids but its influence on their metabolic actions is unproven. Targeted proteolytic cleavage of CBG by neutrophil elastase (NE; ELANE) significantly reduces CBG binding affinity, potentially increasing 'free' glucocorticoid levels at sites of inflammation. NE is inhibited by alpha-1-antitrypsin (AAT; SERPINA1).

Although body mass index (BMI) is widely used as a simple tool to assess obesity, it has certain limitations and inaccuracies. It is known that visceral adipose tissue is closely related to cardiometabolic risks and all-cause mortality; however, precise measurement methods for visceral fat (magnetic resonance imaging and computed tomography) cannot be widely used. Thus, simple but accurate alternatives are valuable.
