CRISPR-assisted detection of RNA-protein interactions in living cells.

We have developed CRISPR-assisted RNA-protein interaction detection method (CARPID), which leverages CRISPR-CasRx-based RNA targeting and proximity labeling to identify binding proteins of specific long non-coding RNAs (lncRNAs) in the native cellular context. We applied CARPID to the nuclear lncRNA XIST, and it captured a list of known interacting proteins and multiple previously uncharacterized binding proteins. We generalized CARPID to explore binders of the lncRNAs DANCR and MALAT1, revealing the method's wide applicability in identifying RNA-binding proteins

Isokinetic muscle strengthening for knee osteoarthritis: A systematic review of randomized controlled trials with meta-analysis

International audienceObjective: To assess the level of scientific evidence and the place in the rehabilitation framework of isokinetic muscle strengthening (IMS) for knee osteoarthritis (OA). Methods: A systematic review of the English literature in MEDLINE via PubMed, the Cochrane Library, and PEDro databases for only randomized comparative trials. Data that were sufficiently homogeneous underwent comprehensive meta-analysis. Methodological assessment was done by using the CLEAR scale for non-pharmacologic trials. Results: We identified articles for 9 trials (696 patients). All trials were of low to moderate quality. Tolerance of IMS was considered good. Improvement in muscle strength was better with an IMS program than no treatment or an isometric exercise but did not differ with an aerobic program. We found an important effect for pain (standardized mean difference 1.218 [95% CI 0.899-1.54], P < 0.001) and functional Lequesne index (1.61 [0.40-2.81], P = 0.009) and a moderate effect for the Western Ontario and McMaster Universities Osteoarthritis Index subscore C for disability (0.58 [0.04-1.11], P = 0.03). Conclusions: IMS is an effective way to propose dynamic muscle strengthening for knee OA rehabilitation and has a significant effect on pain and disability. Because of the weak methodology and the great heterogeneity of studies, particularly in IMS protocol and outcome measures, insufficient data are available to provide guidelines about efficacy and strategy. Future clinical trials are needed, but more attention should be paid to the methods of such studies to clarify the role of IMS in the therapeutic armamentarium of knee OA.

Le cancer de la prostate en France en 2001: état des pratiques et facteurs associés à la réalisation d’une prostatectomie totale

International audienceINTRODUCTION: Prostate cancer was the most common cancer in men in France in 2005, and the second cause of male death from cancer. In this study, we analyzed clinical characteristics of patients with prostate cancer diagnosed in France in 2001 with a focus on therapeutic management of localized prostate cancers. PATIENTS AND METHODS: A total of 2181 cases of prostate cancer diagnosed in 2001 from 11 French counties covered by a cancer registry were analyzed. A descriptive study of the clinical characteristics of patients was performed. Parameters studied included age, county, TNM stage, PSA value, Gleason score, D'Amico prognostic group, Charlson's comorbidity index and initial treatment modalities. For localized cancers, multivariate logistic regression analysis identified factors associated with radical prostatectomy. RESULTS: The proportion of localized prostate cancer (T1 or T2) was 86.6 %. The use of invasive curative treatment (radical prostatectomy and radiotherapy) was 58.4 % for localized cancers. Significant differences in therapeutic management were found between counties. Radical prostatectomy was associated with age at diagnosis, D'Amico prognostic group and the presence of comorbidities. CONCLUSIONS: Most of prostate cancers diagnosed in France in 2001 were clinically localized and were treated by invasive therapy. The consequences of these practices remain to be determined given the limited evolution of many prostate cancers and the frequency of adverse events related to invasive treatments
