Aims/hypothesis: Glucose homeostasis, essential for metabolic health, requires coordinated insulin and glucagon activity to maintain blood glucose balance. Dysregulation of glucose homeostasis causes hyperglycaemia and glucose intolerance, hallmark features of type 2 diabetes. While SEC16 homologue B (SEC16B), an endoplasmic reticulum export factor, has been linked to obesity, type 2 diabetes and lipid metabolism, its role in glucose regulation remains poorly defined.

ELOC-mutated renal cell carcinoma (ELOC-RCC), a newly recognized tumor entity in the fifth edition of the WHO Classification of Tumors of Urinary and Male Genital Organ Tumors (5th WHO Classification), presents morphologic and immunohistochemical (IHC) features overlapping those of clear cell RCC (ccRCC), RCC with fibromyomatous stroma (RCC-FMS), and clear cell papillary renal cell tumor (ccPRCT). Confirmation of an ELOC mutation is required for a definitive diagnosis. This study aims to enhance the understanding of ELOC-RCC's morphologic and molecular characteristics and to develop an affordable and practical panel for its preliminary differentiation based on morphologic and IHC features.

The epithelial-mesenchymal transition (EMT), a fundamental biological process in cancer proliferation and progression, is intricately linked to the interactions between TAMs and cancer cells. However, the underlying mechanisms of EMT and how EMT-programmed cancer cells specifically modulate Arg1 expression in M2-like TAMs remain incompletely understood.

However, the mechanisms that suppress adipose thermogenesis and energy dissipation in obesity are not fully understood. This study identifies mitochondrial carrier homolog 2 (MTCH2), an obesity susceptibility gene, as a negative regulator of energy homeostasis across flies, rodents, and humans.

The development of next-generation vaccines is a continuing and long-term need. In our prior research, the recombinant protein vaccine HR121 targeting the heptad repeat (HR) 1 domain of S2 subunit was constructed, which could evoke highly broad-spectrum neutralizing antibodies in vivo and confer efficient protective effect on several SARS-CoV-2 variants within multiple animal models.

In this study, we investigate how non-nutritive sweetener sucralose to promote acute food intake in the fruit fly Drosophila melanogaster. Our results showed that acute exposure to NNSs sweetness induces a robust hyperphagic response in flies.

Despite the existence of several protocols for generating germ-free (GF) , their reproducibility has been constrained by the technical difficulty of maintaining airtight conditions in centrifuge tubes.

Rodents are recognized as a natural reservoir of pathogens, and many Bartonella species transmitted by various blood-sucking arthropods have been detected in various rodents populations.

This condition is strongly associated with the risk of cardiovascular disease (CVD), but how MAFLD affects the development and progression of CVD, particularly concerning vascular calcification, remains unclear. Herein, extracellular vesicles (EVs) are identified from steatotic hepatocytes as a trigger that accelerated the progression of both vascular intimal and medial calcification.
