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…

The aims of the study were to evaluate the influence of level of spinal cord injury (SCI) on caloric intake relative to total daily energy expenditure (TDEE) and body composition, and to develop a SCI–specific correction factor for the TDEE estimation.
Individuals with paraplegia (PARA, n = 28) and tetraplegia (TETRA, n = 13) were analyzed. Daily caloric intake, basal metabolic rate, and TDEE were obtained using dietary recall, indirect calorimetry, and prediction equations, respectively. Caloric intake and TDEE were adjusted to bodyweight. Body composition was assessed using dual-energy x-ray a…

ConclusionsThese results suggest that compared with PI-RADS v2, PI-RADS v2.1 could be preferable for evaluating TZ lesions.

Conclusion: Standardized evaluation of TIL levels may provide valuable prognostic information in a spectrum of different malignancies.

Aim: To investigate and validate predictive value of combination of pretreatment monocyte-to-lymphocyte ratio (MLR) and neutrophil-to-lymphocyte ratio (NLR) for disease free survival (DFS) and overall survival (OS) in nonmuscle invasive bladder cancer after transurethral resection. Materials &methods: Total 358 patients enrolled were assigned into three (MLR-NLR 0, 1 and 2) groups per the cut-off values of MLR and NLR. Results: Kaplan-Meier curves showed MLR, NLR and their combination were statistically associated with DFS (p

CONCLUSIONS: Learning curve in RARC-iON has a significant impact on achievement of Trifecta. This tool combines accurate measurement of surgical proficiency with an independent predictive value in assessing 3-yr OS probabilities.

INTRODUCTION: Robotic assisted radical cystectomy (RARC) is gaining popularity worldwide, although its enthusiastic implementation is supported mainly by retrospective studies. Aim of this review is to compare the outcomes of RARC and open radical cystectomy (ORC) in the setting of randomized controlled trials (RCTs).
EVIDENCE ACQUISITION: Three search engines (PubMed, Embase®, and Web of Science) were queried up to January 1, 2019. Studies selections followed The Preferred Reporting Items fo…

BACKGROUND: To evaluate if multiparametric magnetic resonance (mpMRI)- transrectal ultrasound (TRUS) fusion targeted biopsy (TBx) versus untargeted standard biopsy (SBx) may decrease the rate of pathological upgrading of Gleason score (GS) 3+4 prostate cancer (PCa) at radical prostatectomy (RP). We also evaluated the impact of percent pattern 4 and cribriform glands at biopsy in the risk of GS 3 + 4 = 7 upgrading.
METHODS: 301 patients with GS 3+4 PCa on biopsy (159 SB…

Otrocka-DomagałaSummaryOral cavity tumours and tumour-like lesions are common in dogs and cats, and their diagnosis and classification requires histopathological examination. The aim of this study was to analyse retrospectively oral cavity lesions in dogs and cats in order to evaluate the distribution of inflammatory, hyperplastic and neoplastic lesions manifested as tumours. A total of 486 oral cavity tumours and tumour-like lesions (340 canine; 146 feline), diagno…
