Creatine powers T cells ’ fight against cancer

Creatine, the organic acid that is popularly taken as a supplement by athletes and bodybuilders, serves as a molecular battery for immune cells by storing and distributing energy to power their fight against cancer, according to new UCLA research.The study, conducted in mice and published in the Journal of Experimental Medicine, is the first to show that creatine uptake is critical to the anti-tumor activities of CD8 T cells, also known as killer T cells, the foot soldiers of the immune system. The researchers also found that creatine supplementation can improve the efficacy of existing immunotherapies.“Because oral creatine supplements have been broadly utilized by bodybuilders and athletes for the past three decades, existing data suggest they are likely safe when taken at appropriate doses,” said Lili Yang, a member of the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA and the study’s senior author. “This could provide a clear and expedient path forward for the use of creatine supplementation to enhance existing cancer immunotherapies.”The findings of the paper stem from the Yang lab ’s research into the metabolic needs of tumor-infiltrating lymphocytes, immune cells that travel into tumors to fight cancer. Examining these cells, the team observed that killer T cells taken from inside of tumors possessed a large number of creatine transporter molecules, which sit on cells’ s urfaces an...

Kothapalli, J. Thomas BrennaAbstractBranched chain fatty acids (BCFA) and linear chain/normal odd chain fatty acids (n-OCFA) are major fatty acids in human skin lipids, especially sebaceous gland (SG) wax esters. Skin lipids contain variable amounts of monounsaturated BCFA and n-OCFA, in some reports exceeding over 20% of total fatty acids. Fatty acid desaturase 2 (FADS2) codes for a multifunctional enzyme that catalyz...

This study evaluated outcomes associated with treatment strategies for this nonagenarian population.MethodsTreatment and overall survival for patients 90 years and older with NSCLC in the National Cancer Data Base (2004-2014) were evaluated using logistic regression, the Kaplan-Meier method, and multivariable Cox proportional hazard models.ResultsThe majority (n = 4152, 57.6%) of the 7205 patients 90 years or older with stage I-IV NSCLC did not receive any therapy. For the entire cohort, receiving treatment was associated with significantly better survival when compared with no therapy (5-year survival, 9.3% [95% confidenc...

They are the most common primary brain tumor and account for nearly one-third of all primary brain and spine tumors. Meningiomas can arise from any dural site, however they are infrequently found at the cerebellopontine angle (CPA). While WHO grade I meningiomas are benign and the slowest growing, WHO grade II meningiomas grow significantly faster, d...

The impedance spectra were analyzed by an equivalent circuit model with needle and bar electrodes. Meat traits including cooking loss, color, pH, texture properties and electrical conductivity were measured. The conductivity and pH of pork increased,...

In this study, freshwater and marine migrations of the endangered salmonid North Sea houting (Coregonus oxyrinchus (Linnaeus, 1758)) were investigated using telemetry. Furthermore, physiological samples were collected from North Sea houting and from resident and anadromous populations of the closely related European whitefish (Coregonus lavaretus (Linnaeus, 1758)) to compare hypo-osmotic tolerances. On average, North Sea houting spent 193 days at sea where the mortality was 36%. Most fish returned from sea in the autumn, and river entry correlated inversely with river temperature and positively with discharge. Fish spent a...

Canadian Journal of Zoology, e-First Articles. Recent studies have noted the differential effects of marine versus terrestrial diets on the carbon and nitrogen stable isotope (13C and 15N, respectively) diet-to-tissue discrimination values and incorporation rates for omnivorous and carnivorous mammals. Inaccurate estimates of these parameters may result in misrepresentation of diet composition or in the timing of diet shifts. Here, we present the results of a diet-switch experiment designed to estimate diet-to-tissue discrimination values and incorporation rates for tissues of gray wolves (Canis lupus Linnaeus, 1758) fed a...
