70042, Qiagen). Thus far, two HNF1B alternative splicing variants (ASVs) have been described, however, the complete spectrum, prevalence and role of HNF1B ASVs in tumorigenesis are unclear. Which description applies to alternative mRNA splicing? This is called alternative splicing and can happen because exons are extended or skipped, or introns can be retained instead of being removed. : Software, Formal analysis, Investigation, Data curation; K.N: Data curation, Visualization; J.S. Intensive study of alternative splicing and its link to cancer in recent years has demonstrated that the natural splicing pattern of a variety of genes (TP53, BCL2L1, FGFR2, EGFR, PTEN, etc.) Characterization of the HNF1B ASVs is an important prerequisite for further expression studies to delineate the HNF1B splicing pattern, potential ASVs functional impact, and eventual refinement of HNF1B’s biomarker role.Institute of Biochemistry and Experimental Oncology, First Faculty of Medicine, Charles University, Prague, 12853, Czech RepublicThe samples were provided by The Bank of Biological Material, First Faculty of Medicine, Charles University, and stored in RNAlater according to the manufacturer’s instructions (Thermo Fisher) until the genetic material was isolated.The comparison of the expression between the paired normal and cancer tissues also showed some differences. Genetic information of an organism is stored in the genes, the functional subunits of the genome, arranged in the strands of the DNA double helix in the nucleus. However, in eukaryotes, before the mRNA can be translated into proteins, non-coding portions of the sequence, called introns, must be removed and protein-coding parts, called exons, joined by RNA splicing to produce a mature mRNA.Stay tuned for the next article in this series, when we’ll talk about what alternative splicing means for your experiments.Alternative splicing occurs only in eukaryotes. Finally, we discuss the change in pre-mRNA splicing patterns of serine/arginine-rich (SR) splicing factors under salt stress.Biological and Environmental Sciences and Engineering Division, King Abdullah University of Science and Technology (KAUST), Thuwal, 23955-6900 Saudi Arabia Therefore, our study provided a comprehensive view of AS under salt stress and revealed novel insights into the potential roles of AS in plant response to salt stress.The online version of this article (doi:10.1186/1471-2164-15-431) contains supplementary material, which is available to authorized users.The authors declare that they have no competing interests.We would like to thank members in the Bioscience Core Facility of KAUST for their help with next generation sequencing. Which Description Applies To Alternative Mrna Splicing? Here, we characterize HNF1B ASVs with high sensitivity in carcinomas of the uterine corpus, large intestine, kidney, pancreas, and prostate, with selected paired healthy tissues, using the previously described multiplex PCR and NGS approach. Recent advances in high-throughput technologies have facilitated studies of genome-wide alternative splicing. To obtain the best experience, we recommend you use a more up to date browser (or turn off compatibility mode in Internet Explorer). processing of exons in mRNA that results in a single gene coding for multiple proteins Why can alternative splicing of messenger RNAs (mRNAs) be advantageous for eukaryotic organisms? processing of exons in mRNA that results in a single gene coding for multiple proteins before mRNA can be translated, what must they undergo? (Correct Answer Below) Which Description Applies To Alternative Mrna Splicing? Putative pre-mRNA-splicing factor ATP-dependent RNA helicase DHX32 (EC: 3.6.4.13 ... isoforms i produced by alternative splicing. This work was supported by King Abdullah University of Science and Technology (KAUST), Kingdom of Saudi Arabia.To investigate the global dynamics of AS under salt stress, in this study, we used the Illumina HiSeq platform to perform pair-end RNA sequencing with Arabidopsis plants that were exposed to different concentrations of salt and generated ~110 million pair-end reads (101 bp in length). : Resources; L.P.: Resources; P.D. RNA splicing was first discovered in 1970s in viruses and subsequently in eukaryotes. J.H. ... (GDPR) that applies since 25 May 2018. RNA splicing is an important stage in gene transcription. This information is transcribed from DNA into a messenger RNA (mRNA) template by a process called transcription. Considering the equivocal data about HNF1B ASVs and expression presented in literature, our aim was to characterize the spectrum of HNF1B mRNA splicing variants across different tissues. processing of exons in mRNA that results in a single gene coding for multiple proteins. Furthermore, there is evidence for alternatively splicing events that are often differentially regulated across tissues and during development, as well as among individuals and populations, suggesting that individual isoforms may serve specific spatial or temporal roles.
