Using affinity chromatography on lactose-agarose, five beta-galactoside binding lectins of 14 to 20 kDa were detected in the rat small intestinal mucosa. The prominant proteins of 17 and 19 kDa were purified to homogeneity by 2D-electrophoresis. Direct N-terminal sequencing of the 17 kDa protein and intrachain sequencing of the 19 kDa protein produced sequences which are part of the N-terminal domain of the L-36/galectin-4. A rabbit polyclonal antibody was raised against the 19 kDa lectin, which specifically recognized the 17 and 19 kDa lectins and detected a related 36 kDa protein in human undifferentiated HT29 cells.

Taking into account involvement of the RNA-binding proteins in regulation of activity of poly(ADP-ribose) polymerase 1 (PARP1), a key factor of DNA repair, the effect of the intrinsically disordered protein Sam68 (Src-associated substrate during mitosis of 68 kDa) on catalytic activity of this enzyme was studied. Plasmid containing coding sequence of the Sam68 protein was obtained. Using the obtained construct, conditions for the Sam68 expression in cells were optimized and procedure for protein purification was developed.

The polysaccharide chitosan possesses broad-spectrum antimicrobial properties and has proven effective in controlling various postharvest diseases in fruits. Nevertheless, the fundamental mechanisms underlying its action remain unclear. In this study, the antifungal effects of chitosan with different molecular weights against Fusarium avenaceum, a pathogen causing root rot in Angelica sinensis, were evaluated.

Human organotypic colon in vitro microtissue: unveiling a new window into colonic drug disposition.

Eur J Pharm Sci

The purpose of this study was to evaluate EpiColon, a novel human organotypic 3D colon microtissue prototype, developed to assess colonic drug disposition, with a particular focus on permeability ranking, and compare its performance to Caco-2 monolayers. EpiColon was characterized for barrier function using transepithelial electrical resistance (TEER), morphology via histology and immunohistochemistry, and functionality through drug transport studies measuring apparent permeability (P). Cutoff thresholds for the permeability of FITC-dextran 4 kDa (FD4), FITC-dextran 10 kDa (FD10S), and [C]mannitol were established to monitor microtissue integrity.

Hydrophilic interaction chromatography coupled to high resolution mass spectrometry (HILIC-LC-HRMS): An approach to study natural peptides in Viperidae snake venom.

Although proteins in snake venoms have been extensively studied and characterized, low-mass molecules remain relatively unexplored, mainly due to their low abundance, secondary role in envenomation, and some analytical technique limitations. However, these small molecules can provide new important data related to venom toxins' molecular structure, functions, and evolutionary relationships. This research aimed to characterize molecules below 10 kDa in the venoms of snakes from the Viperidae families (Bothrops, Agkistrodon, and Bitis) and compare two chromatographic approaches: reverse-phase chromatography (RP), a classic technique, and hydrophilic interaction liquid chromatography (HILIC), an alternative technique, both coupled with high-resolution mass spectrometry (HRMS).

9-kDa Granulysin is a protein present in the granules of human activated cytotoxic T lymphocytes and natural killer cells. It has been shown to exert cytolytic activity against a wide variety of microbes: bacteria, fungi, yeast and protozoa. Recombinant isolated granulysin is also capable of inducing tumor cell death, so it could be used as an anti-tumor therapy.
