Sequence-Based Prediction of SARS-CoV-2 Vaccine Targets Using a Mass Spectrometry-Based Bioinformatics Predictor Identifies Immunogenic T Cell Epitopes

The authors leveraged bioinformatics binding prediction tools for human leukocyte antigen (HLA)-I and HLA-II alleles that were developed using mass spectrometry-based profiling of individual HLA-I and HLA-II alleles to predict peptide binding to diverse allele sets.

Yap is Crucial for CAR‐Driven Hepatocyte Proliferation, but not for Induction of Drug Metabolism Genes in Mice

Scientists investigated a direct role of Yap in constitutive androstane receptor (CAR)‐driven hepatomegaly and hepatocyte proliferation using hepatocyte‐specific Yap‐KO mice. AAV8‐TBG‐CRE vector was injected to Yap‐floxed mice for achieving hepatocyte‐specific Yap deletion followed by TCPOBOP‐treatment.

Broccoli Extract Increases Drug-Mediated Cytotoxicity towards Cancer Stem Cells of Head and Neck Squamous Cell Carcinoma

Researchers investigated whether sulforaphane could enhance the chemotherapeutic effects of cisplatin and 5-fluorouracil against head and neck squamous cell carcinomas–cancer stem cells, and its mechanisms of action.

Chelerythrine Suppresses Proliferation and Metastasis of Human Prostate Cancer Cells via Modulating MMP/TIMP/NF-κB System

The addition of chelerythrine significantly inhibited the proliferation of androgen-independent prostate cancer DU145 and PC-3 cells at the concentration of 5 and 10 μM, but not on androgen-dependent prostate cancer LNCaP cells as well as normal prostate epithelial cell line PrEC cells.

Long Non-Coding RNA MIR503HG Inhibits the Proliferation, Migration and Invasion of Colon Cancer Cells via MiR-107/Par4 Axis

MIR503HG negatively regulated its target miR-107. MiR-107 overexpression reversed the anti-tumor effects of MIR503HG overexpression on colon cancer cells. Par4 was a target of miR-107, which was positively regulated by MIR503HG. The promoting effects of MIR503HG silencing on colon cancer cells were eliminated by Par4 overexpression.

Berberine Improves Intralipid-Induced Insulin Resistance in Murine

Scientists showed that berberine administration markedly ameliorated intralipid-induced insulin without affecting blood glucose, which was accompanied by alleviated mitochondrial swelling in skeletal muscle. They used human skeletal muscle cells, AML12 hepatocytes, HUVECs, and CypD knockout mice to investigate metabolic and molecular alternations.

Cytoprotective Autophagy Induction by Withaferin A in Prostate Cancer Cells Involves GABARAPL1

Researchers confirmed autophagy induction by withaferin A (WA) treatment by transmission electron microscopy using three prostate cancer cell lines. Fourteen common genes altered by 8‐ and 16‐hour exposure to WA were identified from human autophagy PCR array and these results were consistent with the RNA‐seq data.
