Geometrically constrained cytoskeletal reorganisation modulates DNA nanostructures uptake.

DNA nanostructures (DNs) have gained popularity in various biomedical applications due to their unique properties, including structural programmability, ease of synthesis and functionalization, and low cytotoxicity. Effective utilization of DNs in biomedical applications requires a fundamental understanding of their interactions with living cells and the mechanics of cellular uptake. Current knowledge primarily focuses on how the physicochemical properties of DNs, such as mass, shape, size, and surface functionalization, affect uptake efficacy.

In vitro antiproliferative effects of sulforaphane on human colon cancer cell line SW620.

The isothiocyanate sulforaphane (SF) has been reported to possess chemopreventive efficiency towards various malignancies including colon cancer. Here, we investigated the antiproliferative and pro-apoptotic effects of SF on colon cancer cell line SW620. We found that SF at concentrations of 10-50 microM inhibits cell viability and proliferation of SW620 cells in a time- and dose-dependent manner, with IC50 being 26 microM (24 h), 24.

Polyphenolic compounds in chemoprevention of colon cancer - targets and signaling pathways.

Colorectal cancer is one of the leading causes of premature death in people worldwide. Due to the fact that malignant conversion of normal colonic cells requires several steps and often proceeds over considerable time periods, primary prevention of this process should include several approaches, with optimization of nutrition and diet being among most important. During past decades, several groups of chemicals (both naturally occurring as well as synthetic) have been studied in terms of their potential chemopreventive role in colorectal cancer development.

[Francisella tularensis infection, or how to outsmart the certain death].

Francisella tularensis is an intracellular bacterial pathogen and is the causative agent of tularemia. Human become infected when manipulating with infected animals (usually rodents) or via arthropod vectors. In spite of the high virulence of the microbe still very little is known about its overall interaction with host cells and virulence factors identified to date show properties different from other bacterial species.
