TL;DR: Using integrated genomic analysis of 264 T-ALL cases, 106 putative driver genes are identified and new mechanisms of coding and noncoding alteration are described, which suggests that different signaling pathways have distinct roles according to maturational stage.
Abstract: Genetic alterations that activate NOTCH1 signaling and T cell transcription factors, coupled with inactivation of the INK4/ARF tumor suppressors, are hallmarks of T-lineage acute lymphoblastic leukemia (T-ALL), but detailed genome-wide sequencing of large T-ALL cohorts has not been carried out. Using integrated genomic analysis of 264 T-ALL cases, we identified 106 putative driver genes, half of which had not previously been described in childhood T-ALL (for example, CCND3, CTCF, MYB, SMARCA4, ZFP36L2 and MYCN). We describe new mechanisms of coding and noncoding alteration and identify ten recurrently altered pathways, with associations between mutated genes and pathways, and stage or subtype of T-ALL. For example, NRAS/FLT3 mutations were associated with immature T-ALL, JAK3/STAT5B mutations in HOXA1 deregulated ALL, PTPN2 mutations in TLX1 deregulated T-ALL, and PIK3R1/PTEN mutations in TAL1 deregulated ALL, which suggests that different signaling pathways have distinct roles according to maturational stage. This genomic landscape provides a logical framework for the development of faithful genetic models and new therapeutic approaches.

TL;DR: In patients with persistently active RA, the combination of anakinra and MTX was safe and well tolerated and provided significantly greater clinical benefit than MTX alone.
Abstract: Objective
To evaluate the efficacy and safety of anakinra in combination with methotrexate (MTX) in patients with active rheumatoid arthritis (RA).
Methods
Patients with moderate-to-severe active RA who were receiving MTX for 6 consecutive months, with stable doses for ≥3 months (those with disease duration of >6 months but <12 years) were randomized into 6 groups: placebo or 0.04, 0.1, 0.4, 1.0, or 2.0 mg/kg of anakinra administered in a single, daily, subcutaneous injection. The primary efficacy end point was the proportion of subjects who met the American College of Rheumatology 20% improvement criteria (attained an ACR20 response) at week 12.
Results
A total of 419 patients were randomized in the study. Patient demographics and disease status were similar in the 6 treatment groups. The ACR20 responses at week 12 in the 5 active treatment plus MTX groups demonstrated a statistically significant (P = 0.001) dose-response relationship compared with the ACR20 response in the placebo plus MTX group. The ACR20 response rate in the anakinra 1.0-mg/kg (46%; P = 0.001) and 2.0-mg/kg (38%; P = 0.007) dose groups was significantly greater than that in the placebo group (19%). The ACR20 responses at 24 weeks were consistent with those at 12 weeks. Similar improvements in anakinra-treated subjects were noted in individual ACR components, erythrocyte sedimentation rate, onset of ACR20 response, sustainability of ACR20 response, and magnitude of ACR response. Anakinra was safe and well tolerated. Injection site reaction was the most frequently noted adverse event, and this led to premature study withdrawal in 7% (1.0-mg/kg group) to 10% (2.0-mg/kg group) of patients receiving higher doses.
Conclusion
In patients with persistently active RA, the combination of anakinra and MTX was safe and well tolerated and provided significantly greater clinical benefit than MTX alone.

TL;DR: Overall analyses, intensive blood-pressure control had no effect on kidney disease progression, however, there may be differential effects of intensiveBlood pressure control in patients with and those without baseline proteinuria, as well as according to the baseline level of proteinuria.
Abstract: Background In observational studies, the relationship between blood pressure and end-stage renal disease (ESRD) is direct and progressive. The burden of hypertension-related chronic kidney disease and ESRD is especially high among black patients. Yet few trials have tested whether intensive blood-pressure control retards the progression of chronic kidney disease among black patients. Methods We randomly assigned 1094 black patients with hypertensive chronic kidney disease to receive either intensive or standard blood-pressure control. After completing the trial phase, patients were invited to enroll in a cohort phase in which the blood-pressure target was less than 130/80 mm Hg. The primary clinical outcome in the cohort phase was the progression of chronic kidney disease, which was defined as a doubling of the serum creatinine level, a diagnosis of ESRD, or death. Follow-up ranged from 8.8 to 12.2 years. Results During the trial phase, the mean blood pressure was 130/78 mm Hg in the intensive-control gro...

TL;DR: The results suggest that aggresomes can be formed by soluble, nonubiquitinated proteins as well as by integral transmembrane ubiquitinated ones, supporting the hypothesis that Aggresome formation might be a general cellular response to the presence of misfolded proteins.
Abstract: Formation of a novel structure, the aggresome, has been proposed to represent a general cellular response to the presence of misfolded proteins (Johnston, J.A., C.L. Ward, and R.R. Kopito. 1998. J. Cell Biol. 143:1883–1898; Wigley, W.C., R.P. Fabunmi, M.G. Lee, C.R. Marino, S. Muallem, G.N. DeMartino, and P.J. Thomas. 1999. J. Cell Biol. 145:481–490). To test the generality of this finding and characterize aspects of aggresome composition and its formation, we investigated the effects of overexpressing a cytosolic protein chimera (GFP-250) in cells. Overexpression of GFP-250 caused formation of aggresomes and was paralleled by the redistribution of the intermediate filament protein vimentin as well as by the recruitment of the proteasome, and the Hsp70 and the chaperonin systems of chaperones. Interestingly, GFP-250 within the aggresome appeared not to be ubiquitinated. In vivo time-lapse analysis of aggresome dynamics showed that small aggregates form within the periphery of the cell and travel on microtubules to the MTOC region where they remain as distinct but closely apposed particulate structures. Overexpression of p50/dynamitin, which causes the dissociation of the dynactin complex, significantly inhibited the formation of aggresomes, suggesting that the minus-end–directed motor activities of cytoplasmic dynein are required for aggresome formation. Perinuclear aggresomes interfered with correct Golgi localization and disrupted the normal astral distribution of microtubules. However, ER-to-Golgi protein transport occurred normally in aggresome containing cells. Our results suggest that aggresomes can be formed by soluble, nonubiquitinated proteins as well as by integral transmembrane ubiquitinated ones, supporting the hypothesis that aggresome formation might be a general cellular response to the presence of misfolded proteins.
