Membrane alteration, anti-virulence properties and metabolomic perturbation of a chionodracine-derived antimicrobial peptide, KHS-Cnd, on two bacteria models.

Antarctic fishes, living in an extreme environment and normally exposed to pathogens, are a promising source of antimicrobial peptides (AMPs). These are emerging as next-generation drugs due to their activity against multidrug resistant (MDR) bacteria. To infect hosts, beyond intrinsic/acquired resistance, MDR species also use virulence factors such as protease secretion.

Unraveling the impact of different liposomal formulations on the plasma protein corona composition might give hints on the targeting capability of nanoparticles.

Nanoparticles (NPs) interact with biological fluids after being injected into the bloodstream. The interactions between NPs and plasma proteins at the nano-bio interface affect their biopharmaceutical properties and distribution in the organ and tissues due to protein corona (PrC) composition, and in turn, modification of the resulting targeting capability. Moreover, lipid and polymer NPs, at their interface, affect the composition of PrC and the relative adsorption and abundance of specific proteins.

miR-331-5p Affects Motility of Thyroid Cancer Cell Lines and Regulates BID Expression.

During tumorigenesis, miRNAs with unbalanced expression profiles can increase the threat of disease progression. Here, we focus on the role of miR-331-5p in the pathogenesis of thyroid cancer (TC). In vitro studies were conducted using TC cell lines after the forced expression and silencing of miR-331-5p.

Virulence of in Cystic Fibrosis: Relationships between Normoxia and Anoxia Lifestyle.

The airways of cystic fibrosis (CF) patients are colonized by many pathogens and the most common is , an environmental pathogen that is able to infect immunocompromised patients thanks to its ability to develop resistance to conventional antibiotics. Over 12% of all patients colonized by harbour multi-drug resistant species. During airway infection in CF, adopts various mechanisms to survive in a hostile ecological niche characterized by low oxygen concentration, nutrient limitation and high osmotic pressure.

Unveiling the protein signature of the human osteosarcoma 3AB-OS cancer stem cell line.

In cancer research today, one of the major challenges is the eradication of cancer stem cells (CSCs) within the tumor mass. These cells play a crucial role in initiating, growing, and maintaining the tumor. Evidence has demonstrated the presence and significance of CSCs in the development and progression of osteosarcoma (OS).
