Popis

The HCC44 cell line is a non-small cell lung cancer (NSCLC) model known for harboring a KRAS mutation, which plays a significant role in cancer progression and treatment resistance. In a study exploring the characteristics of KRAS-driven NSCLC, HCC44 was identified as dependent on malic enzyme 1 (ME1) for viability, suggesting that the KRAS mutation in this cell line enhances the expression of genes involved in glutamine metabolism and redox balance. ME1’s role in generating NADPH aids in countering oxidative stress, which is particularly vital for KRAS-mutant cancer cells undergoing rapid proliferation.

Further research into natural compounds like chromomycin analogs has shown potential therapeutic relevance to HCC44. Chromomycin SA2 and related molecules were evaluated for their cytotoxic effects on HCC44, showing reduced potency compared to other analogs due to modifications in side chains that affect their interaction with DNA. Additionally, the cell line’s response to radiation therapy has been studied, indicating that perturbing glutamine metabolism could sensitize HCC44 to radiation, potentially overcoming some aspects of radioresistance conferred by KRAS mutations.

O značce

Společnost Cytion vznikla v roce 2004 v německém Heidelbergu s jasným vědeckým posláním: dodávat ověřené lidské a zvířecí buněčné linie bez kontaminace, připravené za přísně kontrolovaných laboratorních podmínek.

Postupně se vypracovala ve spolehlivou buněčnou banku, která slouží akademickým laboratořím, biotechnologickým firmám i farmaceutickým výzkumným týmům po celém světě. Klade přitom důraz na reprodukovatelnost výsledků, přísnou kontrolu kvality a dlouhodobá partnerství.
