Skeletal muscle atrophy in clinical and preclinical models of chronic kidney disease: A systematic review and meta-analysis.

Patients with chronic kidney disease (CKD) are often regarded as experiencing wasting of muscle mass and declining muscle strength and function, collectively termed sarcopenia. The extent of skeletal muscle wasting in clinical and preclinical CKD populations is unclear. We evaluated skeletal muscle atrophy in preclinical and clinical models of CKD, with multiple sub-analyses for muscle mass assessment methods, CKD severity, sex and across the different preclinical models of CKD.

FRT-seq: amplification-free, strand-specific transcriptome sequencing.

We report an alternative approach to transcriptome sequencing for the Illumina Genome Analyzer, in which the reverse transcription reaction takes place on the flowcell. No amplification is performed during the library preparation, so PCR biases and duplicates are avoided, and because the template is poly(A)(+) RNA rather than cDNA, the resulting sequences are necessarily strand-specific. The method is compatible with paired- or single-end sequencing.

The DNA sequence of the human X chromosome.

The human X chromosome has a unique biology that was shaped by its evolution as the sex chromosome shared by males and females. We have determined 99.3% of the euchromatic sequence of the X chromosome.
