- Hepatitis C virus (HCV) infection facilitates the development of hepatocellular carcinoma (HCC). Activation of Ras/Raf/MEK/ERK pathway is found in more than 30% human cancers. Here, we revealed a novel mechanism underlying the regulation of hepatoma cell proliferation mediated by HCV. On one hand, h

- Inability to engage with positive stimuli is a widespread problem associated with negative mood states across many conditions, from low self-esteem to anhedonic depression. Though attention retraining procedures have shown promise as interventions in some clinical populations, novel procedures may b

- Molecular titration promotes oscillations and bistability in minimal network models with monomeric regulators.
- Cuba Samaniego C, Giordano G, Kim J, Blanchini F, Franco E.
- ACS synthetic biology.ACS Synth Biol.2016 Jan 21. [Epub ahead of print]
- Molecular titration is emerging as an important biochemical interaction mechanism within synthetic devices built with nucleic acids and the CRISPR/Cas system. We show that molecular titration in the context of feedback circuits is a suitable mechanism to enhance the emergence of oscillations and bis

- … 2012-12-07.Periodic somite segmentation is controlled by the cyclic gene Hes7, whose oscillatory expression depends upon negative feedback with a delayed timing. … The mechanism that regulates the pace of segmentation remains to be determined, but mathematical modeling has predicted that negative feedback with shorter delays would give rise to dampened but more rapid oscillations. …
