Prolactin-releasing peptide (PrRP) is an RF-amide neuropeptide that binds and activates its cognate G protein-coupled receptor, prolactin-releasing peptide receptor (PrRPR), also known as GPR10. PrRP and PrRPR are highly conserved across mammals and involved in regulating a range of physiological processes, including stress response, appetite regulation, pain modulation, cardiovascular function, and potentially reproductive functions. Here we present cryo-electron microscopy structures of PrRP-bound PrRPR coupled to G or G heterotrimer, unveiling distinct molecular determinants underlying the specific recognition of the ligand's C-terminal RF-amide motif.

Background: Physical activity (PA) exerts an important influence on glycemic control in type 2 diabetes (T2D) patients. Alterations in body composition in patients with T2D may be involved in the overall pathophysiologic process, but PAs and alterations in body composition have been poorly studied.

Methods: A total of 615 patients with T2D were selected by convenient sampling.

Somatostatin receptor 5 (SSTR5) is an important G protein-coupled receptor and drug target for neuroendocrine tumors and pituitary disorders. This study presents two high-resolution cryogenicelectron microscope structures of the SSTR5-G complexes bound to the cyclic neuropeptide agonists, cortistatin-17 (CST17) and octreotide, with resolutions of 2.7 Å and 2.

Melanin-concentrating hormone (MCH) is a cyclic neuropeptide that regulates food intake, energy balance, and other physiological functions by stimulating MCHR1 and MCHR2 receptors, both of which are class A G protein-coupled receptors. MCHR1 predominately couples to inhibitory G protein, G, and MCHR2 can only couple to G. Here we present cryo-electron microscopy structures of MCH-activated MCHR1 with G and MCH-activated MCHR2 with G at the global resolutions of 3.

Background: Modifying diet is crucial for diabetes and complication management. Numerous studies have shown that adjusting eating habits to align with the circadian rhythm may positively affect metabolic health. However, eating midpoint, eating duration, and their associations with diabetic kidney disease (DKD) are poorly understood.

As part of our ongoing investigation of natural bioactive substances from the genus of the tribe Fabaceae for agricultural protection, the chemical constituents of the herb were systematically investigated, which led to the isolation of 39 quinolizidine alkaloids (QAs) (-), including 14 new QAs (-) and 14 isoflavones (-). Their structures were elucidated through comprehensive spectroscopic data analysis (IR, UV, NMR, HRESIMS), ECD calculations, and X-ray crystallography. The antitomato spotted wilt virus (TSWV) and antifungal (against , , , and ) and insecticidal (against and ) activities of the isolated compounds were screened using the lesion counting method, mycelial inhibition assay, and spray method, respectively.

Root hairs are tubular-shaped outgrowths of epidermal cells essential for plants acquiring water and nutrients from the soil. Despite their importance, the growth of root hairs is finite. How this determinate growth is precisely regulated remains largely unknown.

Article Synopsis
  • Thermally conductive materials (TCMs) are crucial for managing overheating issues in electronics, with a focus on achieving high in-plane and through-plane thermal conductivity.
  • Researchers introduced self-standing liquid metal@boron nitride (LM@BN) composites, which significantly enhance thermal conductivity with values of 82.2 W (m K) in-plane and 20.6 W (m K) through-plane.
  • The LM@BN composites not only demonstrate exceptional thermal performance but also showcase mechanical strength and durability, making them effective in cooling high-power light-emitting diode modules and paving the way for advanced thermal management solutions.

Background: Hepatocellular carcinoma (HCC) is one of the most frequent cancers and the main cause of cancer-related death worldwide. Ectopic HCC, an extremely rare type of HCC, exhibits a wide range of clinical signs and radiographic features, making preoperative identification challenging.

Case Summary: A 47-year-old man underwent routine abdominal color ultrasonography, which identified an asymptomatic tumor in the left upper abdomen.

This experiment aims to investigate the impact of probiotic feed on growth performance, carcass traits, plasma lipid biochemical parameters, intramuscular fat and triglyceride content, fatty acid composition, mRNA expression levels of genes related to lipid metabolism, and the activity of the enzyme in Sunit sheep. In this experiment, 12 of 96 randomly selected Sunit sheep were assigned to receive the basic diet or the basic diet supplemented with probiotics. The results showed that supplementation with probiotics significantly increased the loin eye area, and decreased plasma triglycerides and free fatty acids, increasing the content of intramuscular fat and triglycerides in the muscle and improving the composition of the fatty acids.

Class B G-protein-coupled receptors (GPCRs), including glucagon-like peptide 1 receptor (GLP1R) and parathyroid hormone 1 receptor (PTH1R), are important drug targets. Injectable peptide drugs targeting these receptors have been developed, but orally available small-molecule drugs remain under development. Here we report the high-resolution structure of human PTH1R in complex with the stimulatory G protein (G) and a small-molecule agonist, PCO371, which reveals an unexpected binding mode of PCO371 at the cytoplasmic interface of PTH1R with G.

Objectives: Clinically, it is very difficult to prevent pathological fracture caused by high recurrence rate of osteolytic disease of proximal femur in children. At present, there is no consensus in clinical studies of which internal fixation method can significantly reduce the probability of recurrence of pathological fracture. The study aims to research the mechanical properties of different internal fixations in the treatment of osteolytic lesions of proximal femur in children by finite element analysis, and to find out the optimal treatment.

Parathyroid hormone (PTH) and PTH-related peptide (PTHrP) are two endogenous hormones recognized by PTH receptor-1 (PTH1R), a member of class B G protein- coupled receptors (GPCRs). Both PTH and PTHrP analogs including teriparatide and abaloparatide are approved drugs for osteoporosis, but they exhibit distinct pharmacology. Here we report two cryo-EM structures of human PTH1R bound to PTH and PTHrP in the G protein-bound state at resolutions of 2.
