Selective targeting of cancer cells is a critical step in cancer diagnosis and therapy. To address this need, DNA aptamers have attracted significant attention as possible targeting ligands. However, while their use in targeting cancer cells in vitro has b ...
The first total synthesis of the alkaloid natural product jerantinine E is based on a selective cyclization of an aminocyclopropane. Preliminary investigations show that it inhibits the polymerization of tubulin, displaying significant cytotoxicity and ant ...
Metastasis is an inefficient process and most cancer cells fail to colonize secondary sites. There are several possible reasons for this. First, the nature of the infiltrating cells is important as a small population of cancer stem cells has been shown to ...
The development of drug resistance, the prime cause of failure in cancer therapy, is commonly explained by the selection of resistant mutant cancer cells. However, dynamic non-genetic heterogeneity of clonal cell populations continuously produces metastabl ...
During tumor progression cells acquire an altered metabolism, either as a cause or as a consequence of an increased need of energy and nutrients. All four major classes of macromolecules are affected: carbohydrates, proteins, lipids and nucleic acids. As a ...
A new BODIPY-phosphane was synthesized and proved to be a versatile tool for imaging organometallic complexes. It also led to easy access to a new family of theranostics, featuring gold, ruthenium and osmium complexes. The compounds' cytotoxicity was teste ...
The appearance of clinically detectable metastases is the end-point of a complex set of biological processes only few cancer cells are capable to complete. Metastatic colonization comprises the most inefficient metastatic steps as it requires a fine-tuned ...
An original synthesis method based on X-ray irradiation produced gold nanoparticles (AuNPs) with two important properties for biomedical research: intense visible photoluminescence and very high accumulation in cancer cells. The nanoparticles, coated with ...
DIGE (difference in gel electrophoresis) proteomics is exploited here to gain insight into the molecular mechanisms of two established ruthenium-based antimetastatic agents, namely trans-[tetrachloro (DMSO) (imidazole)ruthenate(III)] (NAMI-A) and [Ru(eta(6 ...
High-content assays have the potential to drastically increase throughput in cell biology and drug discovery, but handling and culturing large libraries of cells such as primary tumor or cancer cell lines requires expensive, dedicated robotic equipment. We ...
