UBE2T Promotes Radiation Resistance in Non-Small Cell Lung Cancer via Inducing Epithelial-Mesenchymal Transition and the Ubiquitination-Mediated FOXO1 Degradation

Using bioinformatic analyses, researchers found that UBE2T was associated with survival, tumor size, lymph node metastasis and distant metastasis. They used colony formation, EdU incorporation, scratch, transwell assays, flow cytometry, immunofluorescence and western blot to assess the role of UBE2T in vitro and in vivo.

AAV8 Ins1-Cre can Produce Efficient β-Cell Recombination but Requires Consideration of Off-Target Effects

Intraperitoneal AAV8 Ins1-Cre produced efficient β-cell recombination, alongside some hepatic, exocrine pancreas, α-cell, δ-cell, and hypothalamic recombination. Delivery of lower doses via the pancreatic duct retained good rates of β-cell recombination and limited rates of off-target recombination.

Soluble Vegfr3 Gene Therapy Suppresses Multi‐Organ Metastasis in a Mouse Mammary Cancer Model

Scientists showed that psVEGFR‐3 significantly diminished cell growth with and without added VEGF‐C in vitro, and significantly reduced primary tumor growth and tumor metastases to wide‐spectrum organs in vivo.

Emerging Routes to the Generation of Functional β-Cells for Diabetes Mellitus Cell Therapy

Substantial advances have been made in producing mature β-cells from human pluripotent stem cells that respond appropriately to dynamic changes in glucose concentrations in vitro and rapidly function in vivo following transplantation in mice.

Cytochrome P450 1B1 Polymorphism Drives Cancer Cell Stemness and Patient Outcome in Head-and-Neck Carcinoma

From head-and-neck squamous cell carcinoma cell lines not expressing CYP1B1, investigators generated isogenic derivatives expressing the two forms. Proliferation, invasiveness, stem cell characteristics, sensitivity to anticancer agents and transcriptome were analyzed.

Allogeneic Hematopoietic Stem Cell Transplantation from a 2-HLA-Haplotype-Mismatched Family Donor for Posttransplant Relapse: A Prospective Phase I/II Study

In order to explore the possibility of HLA-mismatched hematopoietic stem cell transplantation from family donors beyond haploidentical relatives, the authors conducted a prospective Phase I/II study of 2-HLA-haplotype-mismatched hematopoietic stem cell transplantation (HSCT).

Lineage Reversion Drives WNT Independence in Intestinal Cancer

Scientists showed that while WNT suppression blocked tumor growth in most organoid and in vivo colorectal cancer (CRC) models, the accumulation of CRC-associated genetic alterations enabled drug resistance and WNT-independent growth.

A Missense Mutation in the MLKL Brace Region Promotes Lethal Neonatal Inflammation and Hematopoietic Dysfunction

The authors isolated a mouse strain with a single missense mutation, MlklD139V, that altered the two-helix ‘brace’ that connects the killer four-helix bundle and regulatory pseudokinase domains.

Disseminated Melanoma Cells Transdifferentiate into Endothelial Cells in Intravascular Niches at Metastatic Sites

Researchers combined lineage tracing in a spontaneous metastatic mouse model of melanoma, advanced imaging, and single-cell RNA sequencing approaches to search for pathophysiologically relevant melanoma cellular states.

miR-410 Induces Both Epithelial-Mesenchymal Transition and Radioresistance through Activation of the PI3K/mTOR Pathway in Non-Small Cell Lung Cancer

Scientists demonstrated that PTEN was a direct target of miR-410 by using bioinformatic tools and dual-luciferase reporter assays, and the miR-410-induced epithelial–mesenchymal transition and radioresistance were reversed by PI3K, Akt, and mTOR inhibitors or by restoring the expression of PTEN in non-small cell lung cancer cells.
