Heat-killed 6235 is more effective than live on DSS-induced colitis modulation of intestinal microbiota and MAPK/NF-κB signaling pathways.

This study compared the protective effects of both live 6235 (LLP 6235) and heat-killed 6235 (HK-LP 6235) on ulcerative colitis. Using a dextran sulfate sodium (DSS)-induced colitis mouse model, we evaluated physiological state, colon tissue integrity, inflammatory factors, tight junction (TJ) proteins, and intestinal microbiota variations. The findings demonstrated that both LLP 6235 and HK-LP 6235 have the capacity to mitigate colitis damage, enhance TJ protein levels, and restore colon morphology.

Therapeutic effect of long-acting FGF21 with controlled site-specific modification on nonalcoholic steatohepatitis.

FGF21 plays an active role in the treatment of type 2 diabetes, obesity, nonalcoholic fatty liver disease (NAFLD), and nonalcoholic steatohepatitis (NASH). However, the short half-life and poor stability of wild-type FGF21 limit its clinical application. Previous studies found that PEGylation can significantly increase the stability of FGF21.

Sulforaphane ameliorates non-alcoholic fatty liver disease in mice by promoting FGF21/FGFR1 signaling pathway.

Most studies regarding the beneficial effect of sulforaphane (SFN) on non-alcoholic fatty liver disease (NAFLD) have focused on nuclear factor E2-related factor 2 (Nrf2). But the molecular mechanisms underlying the beneficial effect of SFN in the treatment of NAFLD remain controversial. Fibroblast growth factor (FGF) 21 is a member of the FGF family expressed mainly in liver but also in adipose tissue, muscle and pancreas, which functions as an endocrine factor and has been considered as a promising therapeutic candidate for the treatment of NAFLD.

Pulmonary toxicity and RNA sequencing analyses of mouse in response to exposure to cellulose nanofibrils.

Objective: The growing applications of nanocelluloses in the fields of advanced nanocomposites, electronics, and medical devices necessitate investigation of their potential adverse effects on human health. The lungs are the primary and the most important route for the entry of nanocelluloses into the human body in occupational settings. However, data on the pulmonary toxicity of cellulose nanofibrils (CNFs) and its molecular mechanism are limited.

Resolution of epoetin-induced pure red cell aplasia, successful re-challenge with roxadustat.

The application of erythropoietin (EPO) can bring about a rare but serious complication called anti-EPO antibody-mediated pure red cell aplasia (PRCA). Once the disease is diagnosed, EPO administration should be stopped immediately. However, after the removal of the anti-EPO antibody, treating anaemia in these patients with chronic renal disease with EPO therapy is difficult, as restarting EPO therapy risks the recurrence of anti-EPO antibody-mediated PRCA.

The recombinant Newcastle disease virus Anhinga strain expressing human TRAIL exhibit antitumor effects on a glioma nude mice model.

Oncolytic virus therapy is perhaps the next major breakthrough in cancer treatment following the success in immunotherapy using immune checkpoint inhibitors. However, the potential oncolytic ability of the recombinant newcastle disease virus (NDV) Anhinga strain carried with tumor necrosis factor-related apoptosis inducing ligand (TRAIL) has not been fully explored at present. In the present study, the recombinant NDV/Anh-TRAIL that secretes soluble TRAIL was constructed and the experiment results suggested NDV/Anh-TRAIL as a promising candidate for glioma therapy.

Previous studies have reported that FGF21 is expected to become a new drug for treatment of diabetes. Liraglutide and insulin glargine are the two representative anti-diabetic biological drugs.

Study on antitumor, antioxidant and immunoregulatory activities of the purified polyphenols from pinecone of Pinus koraiensis on tumor-bearing S180 mice in vivo.

Pinecone polyphenols are bioactive dietary constituents that enhance health and help prevent and treat cancer through improving antioxidant and immunoregulatory activities. This study was designed to investigate the antitumor, antioxidant and immunoregulatory activities of the 40% ethanol eluent of polyphenols from pinecone of pinus koraiensis (PPP-40) in Sarcoma 180 (S180)-bearing mice models in vivo. The results of antitumor activity indicated that PPP-40 significantly inhibited S180 tumor growth and the dose of 150mg/kg exhibited the highest antitumor activity.

EGF and curcumin co-encapsulated nanoparticle/hydrogel system as potent skin regeneration agent.

Wound healing is a complex multifactorial process that relies on coordinated signaling molecules to succeed. Epidermal growth factor (EGF) is a mitogenic polypeptide that stimulates wound repair; however, precise control over its application is necessary to reduce the side effects and achieve desired therapeutic benefits. Moreover, the extensive oxidative stress during the wound healing process generally inhibits repair of the injured tissues.

Recombinant Newcastle disease virus expressing P53 demonstrates promising antitumor efficiency in hepatoma model.

Background: Numerous studies have demonstrated that the NDV-mediated gene therapy is a promising new approach for treatment of cancers. P53 plays a vital role in tumor suppression and surveillance. Therefore, we hypothesize that a recombinant NDV expressing P53 would be an ideal agent for the hepatoma therapy.

To accelerate the development of PEGylated FGF-21 for clinical application as a long-acting antidiabetes drug, we prepared ahmFGF-21 (FGF-21 mutant) and PEGylated ahmFGF-21 in Escherichia coli Rosetta (DE3) by high cell density fermentation at a 50-L scale and pilot-scale purification.

Long-lasting hypoglycemic effect of modified FGF-21 analog with polyethylene glycol in type 1 diabetic mice and its systematic toxicity.

Fibroblast growth factor-21 (FGF-21) is a novel metabolic regulator and has the potential to become a powerful therapy to treat diabetes mellitus. However, we found that the clinical application of wild type FGF-21 was influenced by its low intrinsic bio-stability and poor hypoglycemic potency. In this study, The N-terminus of FGF-21 analog (mFGF-21) was PEGylated in a site-specific manner by 20kD methoxy poly-ethylene glycol-propionaldehyde (mPEG-ALD).
