Stem cell-mediated bone regeneration of marine-derived fibrinolytic compound (FGFC-1) loaded carboxymethyl chitosan hydrogels.

Carboxymethyl chitosan (CMC)-based hydrogels (HG) have gained significant attention for therapeutic applications due to their biomimetic properties and biocompatibility. This study explores, for the first time, the regenerative and osteogenic potential of CMC-HG incorporated with a marine fungi-derived fibrinolytic compound, FGFC-1. The inclusion of FGFC-1 did not significantly alter the crucial characteristics of the HGs, including secondary structure, thermal stability, protein adhesion, and in vitro degradation.

Immunomodulatory Effects of L-Arginine-Modified Silkworm Pupae Protein Enteral Nutrition on Murine Intestinal Morphology and Immunity.

L-arginine, a semi-essential amino acid, is well-documented for its role in nitric oxide (NO) synthesis, its anti-inflammatory properties, and its modulation of immune responses. Studies suggest it may improve gut barrier function and reduce inflammation in conditions such as colitis or sepsis. However, its specific efficacy in diabetic enteropathy (a complication of diabetes involving intestinal dysfunction, inflammation, and neuropathy) is less studied.

Recombinant Humanized Collagen Enhances Secreted Protein Levels of Fibroblasts and Facilitates Rats' Skin Basement Membrane Reinforcement.

Collagen and its peptides exhibit remarkable antioxidant activity, superior biocompatibility, and water solubility, making them a significant research focus in skin care. Hence, the recombinant humanized collagen types I, III, and XVII complexed with niacinamide were developed to address damage in human foreskin fibroblasts (HFF-1) caused by ultraviolet radiation and to evaluate basement membrane proteins in a rat skin model. The Cell Counting Kit-8 (CCK-8) assay showed that higher concentrations of the complex increased the survival of damaged cells by approximately 10% and 22%, respectively, compared to the normal group after 16 and 48 h of treatment.

Recent advancement of novel marine fungi derived secondary metabolite fibrinolytic compound FGFC in biomedical applications: a review.

For several decades, products derived from marine natural sources (PMN) have been widely identified for several therapeutic applications due to their rich sources of bioactive sub-stances, unique chemical diversity, biocompatibility and excellent biological activity. For the past 15 years, our research team explored several PMNs, especially fungi fibrinolytic compounds (FGFCs). FGFC is an isoindolone alkaloid derived from marine fungi, also known as staplabin analogs or triprenyl phenol (SMTP).

Advances in Regenerative Dentistry: A Systematic Review of Harnessing Wnt/β-Catenin in Dentin-Pulp Regeneration.

Dentin pulp has a complex function as a major unit in maintaining the vitality of teeth. In this sense, the Wnt/β-Catenin pathway has a vital part in tooth development, maintenance, repair, and regeneration by controlling physiological activities such as growth, differentiation, and migration. This pathway consists of a network of proteins, such as Wnt signaling molecules, which interact with receptors of targeted cells and play a role in development and adult tissue homeostasis.

Stem-Cell-Regenerative and Protective Effects of Squid () Skin Collagen Peptides against HO-Induced Fibroblast Injury.

Recently, there has been a growing interest in collagen peptides derived from marine sources for their notable ability to protect skin cells against apoptosis induced by oxidants. Therefore, the current study aimed to investigate the fundamental properties of collagen peptides, including their physicochemical, thermal, structural, stem-cell-regenerative, and skin-cell-protective effects, in comparison to commercial collagen peptides. The acid-soluble (ASC) and pepsin-soluble (PSC) collagens exhibited three distinct bands on SDS-PAGE, namely α (α and α), β, and γ chains, confirming a type I pattern.
