ABSTRACT Aging determines a multilevel functional decline and increases the risk for cardiovascular pathologies. MicroRNAs are recognized as fine tuners of all cellular functions, being involved in various cardiac diseases. The heart is one of the most affected organs in aged individuals, however little is known about the extent and robustness to which miRNA profiles are modulated in cardiac cells during aging. This paper provides a comprehensive characterization of the aging-associated miRNA profile in the murine cardiac fibroblasts, which are increasingly recognized for their active involvement in the cardiac physiology and pathology. Next- generation sequencing of cardiac fibroblasts isolated from young and old mice revealed that an important fraction of the miRNAs generated by the Meg3-Mirg locus was downregulated during aging. -

Esse processo n~aofoi f´acilpara mim, assim como n~aofoi f´acilpara eles. Por isso, eu primeiramente gostaria de agradecer `as pessoas que tem me apoiado durante toda minha vida. Minha m~aee meu pai, L´eae Rog´erio,foram fundamentais em meu desenvolvimento. Al´emdas qualidades b´asicas que bons pais ensinam a filhos, eles me ajudaram a desenvolver um forte sentido de independ^encia.Essa independ^enciafoi fundamental na minha decis~aode estudar em outro pa´ıs.

Doktorurkunde ausgehändigt am: ................................................................................ Zusammenfassung Eukaryotische messenger-RNAs (mRNAs) müssen diverse Prozessierungsreaktionen durchlaufen, bevor sie der Translationsmaschinerie als Template für die Proteinbiosynthese dienen können. Diese Reaktionen beginnen bereits kotranskriptionell und schließen das Capping, das Spleißen und die Polyadenylierung ein. Erst nach dem die Prozessierung abschlossen ist, kann die reife mRNA ins Zytoplasma transportiert und translatiert werden. mRNAs interagieren in jeder Phase ihres Metabolismus mit verschiedenen trans-agierenden Faktoren und bilden mRNA-Ribonukleoproteinkomplexe (mRNPs) aus. Dieser „mRNP-Code“ bestimmt das Schicksal jeder mRNA und reguliert dadurch die Genexpression auf posttranskriptioneller -

Results: Of 133 patients whose periprostatic fat was examined, 32 (24%) patients had Background: Low-grade and low-stage endometrioid carcinoma of the uterus is thought lymph nodes in the periprostatic fat pads.

All 32 patients had bilateral pelvic of myometrial invasion or superfi cial invasion, some patients develop recurrent disease, lymphadenectomy. 3 of the 5 patients with positive periprostatic lymph nodes had no often in the vaginal apex. There is limited literature on these tumors, but recent analyses metastasis in pelvic lymph nodes, thereby upstaging 3 cases from T3N0 to T3N1.

E08003 Barcelona, Spain. 4Catalan Institution for Research and Advanced Studies, E08010 Barcelona, Spain *correspondence to: [email protected] Abstract Small non-coding RNAs are highly abundant molecules that regulate essential cellular processes and are classified according to sequence and structure. Here we argue that read profiles from size-selected RNA sequencing, by capturing the post-transcriptional processing specific to each RNA family, provide functional information independently of sequence and structure. SeRPeNT is a computational method that exploits reproducibility across replicates and uses dynamic time-warping and density-based clustering algorithms to identify, characterize and compare small non-coding RNAs, by harnessing the power of read profiles. SeRPeNT is applied to: a) generate an extended human annotation with 671 new RNAs from known classes and 131 from new potential classes, b) show pervasive differential processing between cell compartments and c) predict new molecules with miRNA-like behaviour from snoRNA, tRNA and long non-coding RNA precursors, dependent on the miRNA biogenesis pathway. -
