Unique molecular characteristics of NAFLD-associated liver cancer accentuate β-catenin/TNFRSF19-mediated immune evasion.

Background & Aims: The hepatic manifestation of the metabolic syndrome, non-alcoholic fatty liver disease (NAFLD), can lead to the development of hepatocellular carcinoma (HCC). Despite a strong causative link, NAFLD-HCC is often underrepresented in systematic genome explorations.

Methods: Herein, tumor-normal pairs from 100 patients diagnosed with NAFLD-HCC were subject to next-generation sequencing.

Genomic and Epigenomic Features of Primary and Recurrent Hepatocellular Carcinomas.

Background & Aims: Intratumor heterogeneity and divergent clonal lineages within and among primary and recurrent hepatocellular carcinomas (HCCs) produce challenges to patient management. We investigated genetic and epigenetic variations within liver tumors, among hepatic lesions, and between primary and relapsing tumors.

Methods: Tumor and matched nontumor liver specimens were collected from 113 patients who underwent partial hepatectomy for primary or recurrent HCC at 2 hospitals in Hong Kong.

Using two-component systems and other bacterial regulatory factors for the fabrication of synthetic genetic devices.

Synthetic biology is an emerging field in which the procedures and methods of engineering are extended living organisms, with the long-term goal of producing novel cell types that aid human society. For example, engineered cell types may sense a particular environment and express gene products that serve as an indicator of that environment or affect a change in that environment. While we are still some way from producing cells with significant practical applications, the immediate goals of synthetic biology are to develop a quantitative understanding of genetic circuitry and its interactions with the environment and to develop modular genetic circuitry derived from standard, interoperable parts that can be introduced into cells and result in some desired input/output function.
