Summary: Both obesity and aging are linked to metabolic diseases like type 2 diabetes and cardiovascular disease. Chronic low-grade inflammation of adipose tissue plays a role in the progression of these diseases. Obesity and aging lead to alterations in adipose tissue, triggering a pro-inflammatory phenotype in resident immune cells. They also share characteristics such as a higher visceral fat to subcutaneous fat ratio and a reduced lifespan.

Summary: This study reports a non-inflammatory adipose mechanism of high fat-induced insulin resistance mediated by the loss of Pref-1. Pref-1, released from adipose Pref-1+ cells, inhibits MIF release from both Pref-1+ cells and adipocytes. High palmitic acid induces PAR2 expression in Pref-1+ cells, downregulating Pref-1 expression and release in an AMPK-dependent manner. The loss of Pref-1 increases adipose MIF secretion contributing to non-inflammatory insulin resistance in obesity.

Summary: This study investigated the effects of virgin coconut oil (VCO) on body weight, white fat depots, and biochemical and morphological parameters in male Swiss mice fed standard (SD) or high-fat (HFD) diets. The results showed that low-dose VCO supplementation did not improve obesity, had no effects on hepatic or renal function, and had beneficial effects on the lipid profile only in animals fed HFD.

Summary: Limonin, a compound found in citrus fruits, has been found to effectively combat obesity by reducing fat mass and body weight gain, and improving fatty liver and hyperlipidemia caused by a high-fat diet. It also promotes the browning of white adipose tissues and prevents the whitening of brown adipose tissue in mice. These effects are associated with the activation of PGC-1 alpha pathway. Overall, limonin shows great potential for regulating energy balance and treating obesity.

Summary: White adipose tissue browning is detrimental in patients with burn injury and cancer. WAT browning occurs in nonobese mice and can be induced by beta receptor norepinephrine infusion, but obese mice are resistant to sepsis-induced and norepinephrine-induced WAT browning. Obese mice may be protected from sepsis due to the lack of WAT browning and unchanged inflammatory cytokine response.

Summary: White adipose tissue dysfunction is crucial in the pathogenesis of cardiometabolic alterations related to obesity. Dysfunction is characterized by limited expansion capacity, increased adipocyte hypertrophy, altered adipokine secretion, macrophage accumulation and inflammation. Simple tools are needed to identify individuals with dysfunctional adipose tissue who are at risk of developing metabolic alterations. This review highlights the current pathophysiological mechanisms and emerging measurements for assessing white adipose tissue functionality.

Summary: The study found that emodin could reduce body weight and food intake in obese mice, improve glucose tolerance, and decrease blood lipids. Emodin treatment induced beiging of white adipose tissue and increased markers of beige adipocytes in subcutaneous white adipose tissue (scWAT) and brown adipose tissue (BAT). Furthermore, emodin perturbed the lipidomic profiles in scWAT and BAT of obese mice, indicating selective remodeling in tissue lipid content in response to emodin treatment.

Summary: Adipose tissue is important for energy storage and regulating metabolism. Obesity can lead to dysfunction in adipose tissue, affecting the composition and function of stromal cells. Immune cells in adipose tissue play essential roles in regulating adipocyte function. Macrophages, mast cells, innate lymphoid cells, and T cells all have a significant impact on adipocyte progenitor proliferation, differentiation, and lineage commitment.

Summary: Izencitinib, an oral JAK inhibitor, has been developed for the treatment of inflammatory bowel diseases with a focus on optimal efficacy in the gastrointestinal tract and minimal systemic exposures. Nonclinical studies demonstrated that izencitinib had minimal systemic findings and low systemic concentrations in rats and dogs, suggesting the potential for reduced systemic safety concerns. The gut-selective approach of izencitinib highlights the importance of organ-selective drugs in reducing systemic side effects.

Summary: This article provides a detailed account of a public-private collaboration in testing various microphysiological systems and offers considerations for their practical application in decision-making processes. The authors argue that the success of these systems depends more on the cells, reagents, and research staff's technical expertise rather than the devices themselves. Difficulties in extrapolating concentration-response effects in microphysiological systems to human blood or oral exposures, replicating whole organs, and maintaining long-term functionality are identified as critical challenges.

Summary: Immune responses play a crucial role in the regulation and pathogenesis of various human diseases. The immune system can act as a defense mechanism against infection and cancer, but it can also cause tissue damage when the response becomes excessive or uncontrolled. One challenge in drug development is the lack of suitable preclinical human models to study the efficacy and toxicity of immunomodulatory drugs. Recent advancements in human microphysiological systems (MPS) provide a promising platform to evaluate immune responses and reduce reliance on animal models.

Summary: The study used IVT-SAPAS sequencing to analyze the dynamic changes of APA sites during adipogenesis in bovine subcutaneous preadipocytes and intramuscular preadipocytes. The results showed that APA plays an important role in adipocyte differentiation, and UTR-APA switching genes have different trends, with intramuscular preadipocytes tending to use shorter 3'UTR for differentiation. TRIB3, WWTR1, and INSIG1 play important roles in intramuscular preadipocyte differentiation.

Summary: This study investigates the genetic diversity and natural selection of the Pfama-1 gene in Plasmodium falciparum isolates from Cameroon. The study finds a considerable nucleotide and haplotype diversity, as well as specific mutations in Cameroonian isolates. Positive diversifying selection and the identification of selected codon sites suggest the potential implication of these genetic variations in host immune pressure and parasite-binding complex modulation. The findings provide valuable baseline data for malaria vaccine design.

Summary: RSC is an essential ATP-dependent chromatin remodeling complex in Saccharomyces cerevisiae. It regulates nucleosome-depleted regions (NDRs) by sliding flanking nucleosomes away from NDRs. Depletion of RSC leads to nucleosome encroachment in NDRs and transcription initiation defects. The study compared the effects of catalytic-dead Sth1 and rapid depletion of Sth1 on transcription. Rapid depletion of Sth1 reduces recruitment of TBP and Pol II, while the catalytic-dead mutant exhibits a severe reduction in TBP binding but accumulates Pol II in coding regions. The results suggest a role for RSC in transcription elongation and termination processes.

Summary: A novel risk model based on SCUBE3, TNNC1, SPON1, SEPT12 and ULBP1 genes was developed for predicting PMOP risk, with higher risk score indicating higher risk of suffering from PMOP. Significant differences in signaling pathway activities were observed between the high-risk score group and the low-risk score group.

Summary: This study analyzed the expression of Ptpn1 and miR-124-3p in testicular tissues of mice and investigated their regulatory relationship. The results showed that Ptpn1 expression was up-regulated in adult mouse testis compared to juvenile mouse testis, while miR-124-3p expression showed an opposite pattern. Further analysis suggested that the down-regulation of miR-124-3p may contribute to the high expression of Ptpn1 in adult mouse testis.

Summary: This study found that exosomes secreted by young BMSCs can promote the healing of tendon-bone interface after rotator cuff tears. These exosomes can improve extracellular matrix remodeling, osteogenic differentiation, angiogenesis, and stemness of tendon-derived stem cells (TDSCs). The exosomes from young BMSCs have better effects compared to those from aged BMSCs.
