(Submitter supplied) miR-133a-3p is a highly abundant cardiomyocyte-enriched microRNA whose expression is persistently decreased in response to pressure overload (or transverse aortic constriction, TAC) in mice. Overexpression of miR-133a in cardiomyocytes of mouse hearts in vivo (under the control of the Myh6 promoter) decreases pressure overload-induced apoptosis and fibrosis. In previous studies using microarray platforms, we detected numerous mRNAs whose transcript levels were altered by either or both of miR-133a overexpression and pressure overload. more...

(Submitter supplied) Rationale: MicroRNAs play key roles in hypertrophic stress responses. miR-378(-3p) is a highly abundant, cardiomyocyte-enriched microRNA whose downregulation in pressure-overload has been suggested as detrimental to the heart. Previous studies have utilized systemic anti-miR or microRNA-encoding virus administration, and thus questions regarding the cardiomyocyte-autonomous roles of miR-378 remain. Objective: To examine whether persistent overexpression of miR-378 in cardiomyocytes alters the phenotype of the unstressed heart, whether its overexpression is beneficial or deleterious in the setting of pressure-overload, and to comprehensively identify its cardiomyocyte-specific effects on mRNA regulation. Methods and Results: Cardiac function was compared in young (10-12 week-old) mice overexpressing miR-378 in the heart under the control of the Myh6 promoter (alphaMHC-miR-378 mice), in older (40 week-old) mice and their age-matched wild-type controls. Older alphaMHC-miR-378 mice exhibited decreased fractional shortening and modest chamber dilation with an increase in cardiomyocyte length. When subjected to pressure-overload, cardiomyocyte length was increased in young alphaMHC-miR-378 mice, but fractional shortening declined precipitously over two weeks. Transcriptome profiling of wild-type and alphaMHC-miR-378 hearts in unstressed and pressure-overload conditions revealed dysregulation of several upstream metabolic and mitochondrial genes in alphaMHC-miR-378 hearts, compromising the reprogramming that occurs during early adaptation to pressure overload. Ago2 immunoprecipitation with mRNA sequencing revealed novel miR-378 cardiac mRNA targets including Akt1 and Epac2 and demonstrated the contextual nature of previously described miR-378 targeting events. Conclusions: Long-term upregulation of miR-378 levels in the heart is not innocuous and exacerbates contractile dysfunction in pressure-overload hypertrophy through numerous signaling mechanisms.

(Submitter supplied) The role of SRF in the regulation of microRNA expression and microRNA biogenesis in cardiac hypertrophy has not been well established. In this report, we employed a distinct transgenic mouse model to study the impact of SRF on cardiac microRNA expression and microRNA biogenesis. Cardiac-specific overexpression of SRF (SRF-Tg) led to altered expression of a number of microRNAs.

(Submitter supplied) Background: There is a limited capacity to repair damage in the mammalian heart after birth, which is primarily due to the inability of cardiomyocytes to proliferate after birth. This is in contrast to zebrafish and salamander, in which cardiomyocytes retain the ability to proliferate throughout life and can regenerate their heart after significant damage. Recent studies in zebrafish and rodents implicate microRNAs (miRNAs) in the regulation of genes responsible for cardiac cell cycle progression and regeneration, in particular, miR-133a, the miR-15 family, miR-199a and miR-590. more...

(Submitter supplied) We wished to determine the effects of activating the transcription factor, ATF6, on global miRNA expression. We utilized transgenic mice with a conditionally tamoxien-responsive form of ATF6 and assessed cardiac lysates from NTG and TG mice, both treated with tamoxifen and untreated, in order to identify differentially expressed miRNAs. We then focused on miRNAs of interest as well as the genes they are predicted to regulate.

(Submitter supplied) MicroRNAs are small non-coding RNAs that regulate mRNA function. Recent studies have shown that microRNA expression is altered in tumors. We studied the expression of both microRNAs and mRNAs in 60 primary prostate tumors and 16 non-tumor prostate tissues to evaluate the involvement of microRNAs in prostate cancer. Global microRNA expression was determined in RNA isolated from fresh-frozen human tissues with a custom oligonucleotide microarray chip. more...

(Submitter supplied) MicroRNAs (miRNAs) regulate the expression of mRNAs through sequence-specific binding into their 3′ untranslated region (UTR). The seed sequence of miRNAs is the key determinant to recognize the target sites. The paralogous miRNAs, which share the same seed sequences but differ in their 3′ parts, are known to regulate largely overlapping group of miRNAs. However, there is still no study which analyzes the functional difference among paralogous miRNAs. more...

(Submitter supplied) Despite the efforts in defining the molecular mechanisms for the drug resistance in colorectal cancers, little is known about the roles of microRNAs. With microarray containing 723 microRNAs, we examined effect of 5-fluorouracil (5-FU) on the microRNA expression. Respond to 5-FU, we identify two microRNAs, miR-19b and miR-21, that were differentially expressed in 5-FU resistant colon cancer cells derived from KM12C and DLD-1.
