Description
The heart uses primarily fatty acids and glucose for deriving energy. The majority of energy in the healthy heart derives from fat utilization, with the remainder coming primarily from the catabolism of glucose. Classical studies by Randle and colleagues describe the ability of the heart to switch its mode of utilization facilely and reversibly between glucose and fatty acids (myocardial glucose-fatty acid cycle or Randle cycle). However, under conditions of pathological stress, reliance of the heart on fatty acids decreases with a concomitant increase in reliance on glucose. It is unclear how such changes in metabolism regulate gene expression in the heart. Therefore, we examined how regulation of glycolysis at the level of phosphofructokinase modulates gene expression in the heart. We performed transcriptomic analysis of hearts from mice expressing either kinase-deficient phosphofructokinase 2 (GlycoLo) or phosphatase-deficient phosphofructokinase 2 (GlycoHi) under the control of the -MHC promoter, which restricted expression of the transgenes to the heart. Phosphofructokinase 2 only controls the ability of the myocyte to regulate abundance of a single metabolite, F-2,6-P2, which is an allosteric regulator of the rate-limiting and committed step in glycolysis. Parallel radiometric and metabolomic studies showed the expected increases or decreases in glycolytic flux along with diametrically opposite changes in fat metabolism, which is consistent with the myocardial glucose-fatty acid cycle. Transcriptomic analyses showed remarkable changes in gene transcription in these hearts, which indicates that glucose and/or fatty acid metabolism is a driver of transcriptional programs in the heart. Furthermore, glycolytic activity coordinately regulated numerous genes in the heart, including genes important for cardiac remodeling as well as genes regulating gluconeogenic and ancillary biosynthetic pathway activity. These findings reveal that glycolytic rate is a critical regulator of gene expression in the heart and can coordinate programs that modulate cardiac metabolism, growth, and hypertrophy.

Description
Global microarray (HG U133 Plus 2.0) was used to investigate the effects of resistance exercise and resistance training on the skeletal muscle transcriptome profile of 28 young and old adults. Vastus lateralis muscle biopsies were obtained pre and 4hrs post resistance exercise in the beginning (untrained state) and at the end (trained state) of a 12 wk progressive resistance training program.

Description
The molecular mechanisms underlying asplenia, a condition often associated with overwhelming infections remain largely unknown. During spleen development, the transcription factor TLX1 controls morphogenesis and organ expansion, and loss of it causes spleen agenesis. However, the downstream signaling pathways that are deregulated in the absence of TLX1 are mostly unknown. Herein, we demonstrate that loss of Tlx1 in the splenic mesenchyme causes increased retinoic acid (RA) signaling. Increased RA activity causes premature differentiation of the splenic mesenchyme and reduced vasculogenesis of the splenic anlage. Moreover, excess or deficiency in RA signaling, as observed in Cyp26b1 or Rdh10 mutants respectively, also results in spleen growth arrest. Genome-wide analysis revealed that TLX1 binds RA-associated genes through the AP-1 site and cooperates with the AP-1 family transcription factors to regulate transcription. Pharmacological inhibition of RA signaling partially rescues the spleen defect. These findings establish the critical role of TLX1 in controlling RA metabolism, and provide novel mechanistic insights into the molecular determinants underlying congenital asplenia.

Description
We report an applicaton of small RNA sequencing using high throughput next generation sequencing to identify the small RNA content of cell lines. By sequencing over 30 million reads we could identify a new class of small RNAs previousy observed with tiling arrays and mapping to promoter regions of coding genes. We also identified a large number of small RNAs corresponding to internal exons of coding genes. By using different enzymatic treatments and immunoprecipitation experiments, we have determined that both the promoter associated small RNAs as well as ones within the body of the genes bear 5'' cap structures. Overall design: Examination of the expression of small RNAs (<200nt).
