Treatment of invasive brain tumors using a chain-like nanoparticle

Glioblastoma multiforme is generally recalcitrant to current surgical and local radiotherapeutic approaches. Moreover, systemic chemotherapeutic approaches are impeded by the blood-tumor barrier. To circumvent limitations in the latter area, we develop...

miR-22 Impedes DDR Function of MDC1

MDC1 is critical component of the DNA damage response (DDR) machinery and orchestrates the ensuring assembly of the DDR protein at the DNA damage sites, and therefore loss of MDC1 results in genomic instability and tumorigenicity. However, the molecul...

MicroRNA-22 Suppresses DNA Repair and Promotes Genomic Instability by MDC1 Targeting

MDC1 is critical component of the DNA damage response (DDR) machinery and orchestrates the ensuring assembly of the DDR protein at the DNA damage sites, and therefore loss of MDC1 results in genomic instability and tumorigenicity. However, the molecula...

Emergence of drug tolerance in cancer cell populations: an evolutionary outcome of selection, non-genetic instability and stress-induced adaptation

In recent experiments on isogenetic cancer cell lines, it was observed that exposure to high doses of anti-cancer drugs can induce the emergence of a subpopulation of weakly-proliferative and drug-tolerant cells, that display markers associated with st...

miR-340 suppresses the stem-like cell function of glioma-initiating cells by targeting tissue plasminogen activator

Glioma-initiating cells (GICs) have stem-like cell properties thought to be sufficient for recurrence, progression and drug resistance in glioblastomas. In the present study, we defined miR-340 as a differentially expressed microRNA (miRNA) in human GI...
