Proteomics and Phosphoproteomics Characteristics of the Rhesus Macaque Lung Infected With Original SARS-CoV-2, Delta, and Omicron Variants.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) strains mutate rapidly, making it crucial to study their molecular mechanisms for swift vaccine and drug development. Here, we utilized host lung proteomic and phosphoproteomic profiling to investigate the underlying pathology caused by the variants. Lung tissues infected with wild-type GD108, Delta, or Omicron BA.

Azvudine is a thymus-homing anti-SARS-CoV-2 drug effective in treating COVID-19 patients.

Azvudine (FNC) is a nucleoside analog that inhibits HIV-1 RNA-dependent RNA polymerase (RdRp). Recently, we discovered FNC an agent against SARS-CoV-2, and have taken it into Phase III trial for COVID-19 patients. FNC monophosphate analog inhibited SARS-CoV-2 and HCoV-OC43 coronavirus with an EC between 1.

Comparative medical characteristics of ZDF-T2DM rats during the course of development to late stage disease.

Background: There are few reports on the comparative medical characteristics of type 2 diabetes models in late stage. An analysis of comparative medical characteristics of Zucker diabetic fatty type 2 diabetes mellitus (ZDF-T2DM) rats during the course of development to late stage disease was performed.

Methods: In this study, ZDF rats were fed with high-sugar and high-fat diets to raise the fasting blood glucose, and develop of type 2 diabetes.

Type 2 diabetes mellitus non-genetic Rhesus monkey model induced by high fat and high sucrose diet.

To build an ideal animal model for studying the mechanism of occurrence, developing and treating of diabetes become a more important issue, facing with the fact that the big threat of diabetes to human health has been worsen. First, we used the normal control diets or the high-fat/high-sucrose diets to feed the adult rhesus monkeys and the macaques induced by the high-fat/high-sucrose diets in the high-fat/high-sucrose group and the type 2 diabetes mellitus (T2DM) group developed the hyperglycemia, hyperinsulinemia at 6 months in accordance with the precious researches that reported that minipigs, rats and mice could develop hyperglycemia, hyperinsulinemia, hyperlipidemia and obesity after being induced with high-fat/high-carbohydrate diets. Second, the rhesus monkeys in T2DM group were injected STZ at a low dosage of 35 mg/kg BW to induce glucose persistent elevation which maintained pretty well after 12 months.

Dopaminergic neuron-like cells derived from bone marrow mesenchymal stem cells by Lmx1α and neurturin overexpression for autologous cytotherapy in hemiparkinsonian rhesus monkeys.

Bone marrow-derived mesenchymal stem cells hold great potential for cytotherapeutics of neurodegenerative disorders, including Parkinson's disease. The neurotrophic factor neurturin can rescue dopaminergic neurons damaged during the disease process. Lmx1α can promote mesencephalic dopaminergic differentiation during embryogenesis.

Rapid cloning and comparative sequence analysis of full-length cDNA of Rhesus monkey (Macaca mulatta) resistin.

Resistin protein is thought to link insulin resistance in murine models of obesity and type-2 diabetes, but the role of resistin in human studies of inflammatory metabolic disorders have generated conflicting data. Here, we describe the structure of the resistin gene using adipose tissue from non-human primates (NHPs), which have been used extensively to model a host of human diseases. Full-length cDNA from rhesus macaque resistin obtained by rapid amplification of cDNA ends (RACE) is comprised of 526 nucleotides covering an open-reading frame (ORF) that encodes a 108-amino-acid protein that is 92% homologous with the human counterpart but only 60% homologous with the murine counterpart.
