(Submitter supplied) Background: MicroRNAs (miRs) are small non-coding RNAs that regulate gene (mRNA) expression. Although pathological role of miRs have been studied in muscle wasting conditions such as age, obesity, starvation and muscular dystrophy, their roles in Cancer Cachexia CC are still emerging. Objectives: (i) to profile human skeletal muscle expressed miRs; (ii) to identify differentially expressed (DE) miRs between cachectic and non-cachectic cancer patients; (iii) to identify mRNA targets for the DE miRs to gain mechanistic insights and (iv) to investigate if miRs show potential prognostic and predictive value. more...

(Submitter supplied) Alternative splicing (AS) is a post-transcriptional gene regulatory mechanism that contributes to proteome diversity. Aberrant splicing mechanisms (mutations, polymorphisms, insertion/deletion etc.) contribute to various cancers and muscle related conditions such as Duchenne muscular dystrophy. However, dysregulation of AS in Cancer Cachexia (CC) patients remains unexplored. Our objectives were (i) to profile alternatively spliced genes (ASGs) on a genome-wide scale, and (ii) to identify DE alternatively spliced genes (DASGs) associated with CC. more...

(Submitter supplied) The genetic closeness and divergent muscle growth rates of broilers and layers make them great models for myogenesis study. In order to discover the molecular mechanisms determining the divergent muscle growth rates and muscle fiber sizes in different chicken lines, we systematically identified differentially expressed genes between broilers and layers during muscle development (embyonic day 10, 12, 14 and 18) by microarray hybridization experiment.

(Submitter supplied) In the current study, we expanded our previous work to identify miRNAs implicated in the myogenesis regulation through the comparison of miRNAs transcriptome in skeletal muscle tissues between broilers and layers. To address that, we firstly performed Solexa deep sequencing to profile miRNAs expressed in chicken skeletal muscle tissues. Sequence tags analyses not only enable us to report a group of highly abundant known miRNAs expressed in skeletal muscles but most importantly to identify novel putative chicken miRNAs from skeletal muscle tissue. more...

(Submitter supplied) Background In the past, numerous studies revealed that supplementation with carnitine has multiple effects on performance characteristics and gene expression in livestock and model animals. The molecular mechanisms underlying these observations are still largely unknown. Increasing evidence suggests that microRNAs (miRNAs), a class of small non-coding RNA molecules, play an important role in post-transcriptional regulation of gene expression and thereby influencing several physiological and pathological processes. more...

(Submitter supplied) Prognostication of Breast Cancer (BC) relies largely on traditional markers such as hormone or growth factors but due to their suboptimal specificities, it is challenging to identify the subset of patients who are likely to undergo recurrence and markers of higher specificity are sought to guide therapies. MicroRNAs (miRNAs) are small non-coding RNAs which function as post-transcriptional regulators of gene expression and have shown promise as potential prognostic markers in several cancer types including BC. more...

(Submitter supplied) Purpose: MicroRNAs (miRNAs) are non-coding small miRNA ~22 nucleotides in length and play a vital role in muscle development by binding to messenger RNAs (mRNAs). Large White (LW, a lean type pig) and Meishan pigs (MS, a Chinese indigenous obese breed) have significant postnatal phenotype differences in growth rate, muscle mass and meat quality, and theses difference are programmed during prenatal muscle development.To shed directly light on the miRNA transcriptome difference in prenatal muscles between these two distinct pig breeds. more...

(Submitter supplied) Cancer cachexia is a metabolic multifactorial syndrome that causes up to 20% of cancer-related deaths. Muscle atrophy, the hallmark of cancer cachexia, strongly impairs the quality of life of cancer patients; however, the underlying pathological process is still poorly understood. In our study, the transcriptome of cachectic gastrocnemius muscle in the C26 xenograft model was comparied with normal control. more...

We have identified the genome wide target genes and biological networks regulated by FoxO in skeletal muscle during Colon-26 (C-26) cancer cachexia. In this dataset, we include the expression data obtained from the tibialis anterior muscles of control and severely cachectic Colon-26 mice in which FoxO-dependent transcription was either intact (AAV9-EV) or inhibited (AAV9-d.n.FoxO). more...

(Submitter supplied) Gene expression profiles were generated from muscle biopsies from 134 individuals, and differences in expression based on sex were explored. Top differentially expressed gene lists are often inconsistent between studies and it has been suggested that small sample sizes contribute to lack of reproducibility and poor prediction accuracy in discriminative models. We considered sex differences (69♂, 65♀) in 134 human skeletal muscle biopsies using DNA microarray. more...
