Exon usage analysis in in vitro cultured fibroblast cells. To assay the genome-wide splicing changes during cellular senescence, we performed splicing analysis on young and old normal fibroblasts, and in fibroblasts +/- tert (telomerase protein subunit Tert immortalized).
Progerin and telomere dysfunction collaborate to trigger cellular senescence in normal human fibroblasts.

View SamplesThe orphan nuclear receptor Ftz-F1 is expressed in all somatic nuclei in Drosophila embryos but mutations result in a pair-rule phenotype. Previously characterized Ftz-F1 target genes were co-regulated by Ftz, which is expressed in stripes, consistent with the pair-rule phenotype observed for ftz-f1 and ftz mutants. However, attempts to identify new target genes on the basis of Ftz-F1 and Ftz binding sites alone has met with only limited success. To discern the rules for Ftz-F1 target site selection in vivo and to identify additional target genes, a microarray analysis was performed comparing wildtype and ftz-f1 mutant embryos.

View SamplesPresence of ectopic lipid droplets (LDs) in cardiac muscle is associated to lipotoxicity and tissue dysfunction. However, presence of LDs in heart is also observed in physiological conditions, such as at times when cellular energy needs and energy production from mitochondria fatty acid (FA) -oxidation are high (fasting). This suggests that development of tissue lipotoxicity and dysfunction is not simply due to the presence of LDs in cardiac muscle but due at least in part to alterations in LD function. To examine the function of cardiac LDs, we obtained transgenic mice with heart-specific plin5 over-expression (MHC-plin5), a member of the perilipin protein family. Hearts from MHC-plin5 mice expressed at least 4-fold higher levels of plin5 and exhibit a 3.5- fold increase in triglyceride content versus non-transgenic littermate. Chronic cardiac excess of LDs was found to result in mild heart dysfunction with decreased expression of PPAR target genes, decreased mitochondria function and left ventricular concentric hypertrophia. Lack of more severe heart function complications may have been prevented by a strong increased expression of oxidative induced genes via NF-E2-related factor 2 anti-oxidative pathway. Perilipin 5 regulates the formation and stabilization of cardiac LDs, and promotes cardiac steatosis without major heart function impairment.
Cardiomyocyte-specific perilipin 5 overexpression leads to myocardial steatosis and modest cardiac dysfunction.

We identified an essential regulator of salt stress RSA3 and used the Affymetrix whole-genome arrays to study the effect of rsa3-1 mutation on global gene expression under salt stress. A set of genes differentially expressed in rsa3-1 under salt stress are identified.
