Dividing T Cells Inherit Uneven Enzyme Activity: A Potential Target for Improving Cancer Immunotherapy

mTORC1.JPG

When an immune T cell divides into two daughter cells, the activity of an enzyme called mTORC1, which controls protein production, splits unevenly between the progeny, producing two cells with different properties. Such "asymmetric division," uncovered by Johns Hopkins Kimmel Cancer Center researchers using lab-grown cells and specially bred mice, could offer new ways to enhance cancer immunotherapy and may have other implications for studying how stem cells differentiate.

Study Finds Potential Treatment for Non-Alcoholic Fatty Liver Disease

Researchers report in the journal Cell Reports a targeted molecular therapy that dramatically reduces the initial development of Non Alcoholic Fatty Liver Disease (NAFLD) in laboratory mouse models of the disease. The study, published online June 30, found increased levels of an enzyme called cdk4 in patients with NAFLD and in mouse models. Using two drugs that inhibit cdk4 in mouse models reduced development of hepatic steatosis – the first stage of the disease.

Gene Mutation “Hotspots” Linked to Better Breast Cancer Outcomes

kataegis.jpg

Using a database of human tumor genomic data, researchers at the University of California San Diego, School of Medicine and Moores Cancer Center discovered that mutation hotspots known as kataegis are a positive marker in breast cancer — patients with kataegis have less invasive tumors and better prognoses. The study, published June 30 in Cell Reports, also suggests kataegis status could help doctors determine treatment options that might work best for patients with the mutation pattern.

Unlocking the Secrets of Nerve Regeneration

Nerves in the central nervous system of adult mammals do not usually regenerate when injured. The granule cell, a nerve cell located in the cerebellum, is different. When its fibres, called parallel fibres, are cut, rapid regeneration ensues and junctions with other neurons called "synapses" are rebuilt. The precise mechanism for this was unclear.

Everolimus R-CHOP Combination Safe for Treating Diffuse Large B-Cell Lymphoma

ROCHESTER, Minn. — The targeted therapy everolimus may be safely combined with R-CHOP for new, untreated diffuse large B-cell lymphoma according to the results of a pilot study by Mayo Clinic researchers published in the Lancet Haematology. R-CHOP is a combination of drugs used to treat lymphoma. The combination includes rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone.
