The Microfluidic Environment Reveals a Hidden Role of Self-Organizing Extracellular Matrix in Hepatic Commitment and Organoid Formation of hiPSCs

Hepatic progenitor cells either derived in microfluidics or exposed to exogenous ECM stimuli showed a significantly higher potential of forming hepatic organoids that could be rapidly expanded for several passages and further differentiated into functional hepatocytes.

Hypoxia Induces Sorafenib Resistance Mediated by Autophagy via Activating FOXO3a in Hepatocellular Carcinoma

Investigators demonstrated here that hypoxia significantly attenuated sensitivity of hepatocellular carcinoma (HCC) cells to sorafenib treatment and reduced its proliferation. Autophagy was observed in sorafenib-treated HCC cells in hypoxia, and inhibition of autophagy by 3-MA eliminated hypoxia-induced sorafenib resistance.

MicroRNA-9-5p Regulates the Mitochondrial Function of Hepatocellular Carcinoma Cells through Suppressing PDK4

Scientists attempted to investigate the potential role of miR-9-5p in the progression of hepatocellular carcinoma (HCC). Expression of pyruvate dehydrogenase kinase 4 and miR-9-5p was examined in HCC tissues collected from HCC patients and cell lines.

Evidence for Liver and Peripheral Immune Cells Secreting Tumor-Suppressive Extracellular Vesicles in Melanoma Patients

The authors mimicked the interaction of tumor cells with liver cells and PBMC in vitro, and compared newly secreted extracellular vesicle (EV)-associated miRNAs and protein factors with those detected in melanoma patient`s plasma EV.

MCPIP1 Reduces HBV-RNA by Targeting Its Epsilon Structure

Overexpression of monocyte chemotactic protein-1-induced protein 1 (MCPIP1) decreased hepatitis B virus (HBV) RNA, whereas ablating MCPIP1 in vitro enhanced HBV production. The domains responsible for RNase activity or oligomerization, were required for MCPIP1-mediated viral RNA reduction.

In Vitro-Transcribed Antigen Receptor mRNA Nanocarriers for Transient Expression in Circulating T Cells In Vivo

In mouse models of human leukemia, prostate cancer and hepatitis B-induced hepatocellular carcinoma, repeated infusions of these polymer nanocarriers induced sufficient host T cells expressing tumor-specific CARs or virus-specific TCRs to cause disease regression at levels similar to bolus infusions of ex vivo engineered lymphocytes.
