Resveratrol differentially regulates NAMPT and SIRT1 in Hepatocarcinoma cells and primary human hepatocytes. [PDF]

PLoS ONE, 2014
Resveratrol is reported to possess chemotherapeutic properties in several cancers. In this study, we wanted to investigate the molecular mechanisms of resveratrol-induced cell cycle arrest and apoptosis as well as the impact of resveratrol on NAMPT and ...

Exosomes released by hepatocarcinoma cells endow adipocytes with tumor-promoting properties

Journal of Hematology & Oncology, 2018
BackgroundThe initiation and progression of hepatocellular carcinoma (HCC) are largely dependent on its local microenvironment. Adipocytes are an important component of hepatic microenvironment in nonalcoholic fatty liver disease (NAFLD), which is a ...

Structure‐Guided Engineering of a Cas12i Nuclease Unlocks Near‐PAMless Genome Editing

Advanced Science, EarlyView.
CRISPR‐Cas nucleases are limited by PAM requirements, restricting genome accessibility. Structure‐guided engineering of the compact Cas12i nuclease SF01 produced three variants with near‐PAMless, enabling efficient editing at diverse 5'‐NNTN‐3' sites. These nucleases expand the editable portion of the human genome more than fourfold, enabling efficient

TGFβ1 Activates Lnc‐APUE to Promote Tumor Metastasis via the Alu Element‐Driven STAU1‐Mediated Decay of CDH1 mRNA

Advanced Science, EarlyView.
We delineate a TGFβ1/SMAD/lnc‐APUE/E‐cadherin axis wherein TGFβ1 signaling activates lnc‐APUE; lnc‐APUE subsequently downregulates E‐cadherin expression via Alu element‐driven STAU1‐mediated decay of CDH1 mRNA, thereby promoting tumor metastasis. Our findings reveal a novel regulatory function for lnc‐APUE within the SMD pathway, elucidate a distinct ...

Multicystic Hepatocarcinoma Mimicking Liver Abscess [PDF]

Case Reports in Surgery, 2013
The diagnosis of hepatocellular carcinoma (HCC) became easier in relation to the improved radiological examinations; however, the neoplasm may occur under atypical presentations mimicking other benign or malignant processes. Multicystic HCC mimicking a liver abscess associated with septic-type fever and leukocytosis is rare, has a poor prognosis, and ...

T Cell Exhaustion in Cancer Immunotherapy: Heterogeneity, Mechanisms, and Therapeutic Opportunities

Advanced Science, EarlyView.
T cell exhaustion limits immunotherapy efficacy. This article delineates its progression from stem‐like to terminally exhausted states, governed by persistent antigen, transcription factors, epigenetics, and metabolism. It maps the exhaustion landscape in the TME and proposes integrated reversal strategies, providing a translational roadmap to overcome
