Tsix defective in splicing is competent to establish Xist silencing.

Dosage differences of X-linked genes between male and female mammals are compensated for by a mechanism known as X-inactivation, and the noncoding Xist gene plays a crucial role in this process. The expression of Xist is regulated in cis by its noncoding antisense gene, Tsix, whose transcripts (though a fraction of them stay unspliced), are processed like common proteincoding RNAs. It has been ...

A Combinatorial Code for Splicing Silencing: UAGG and GGGG Motifs

Alternative pre-mRNA splicing is widely used to regulate gene expression by tuning the levels of tissue-specific mRNA isoforms. Few regulatory mechanisms are understood at the level of combinatorial control despite numerous sequences, distinct from splice sites, that have been shown to play roles in splicing enhancement or silencing. Here we use molecular approaches to identify a ternary combin...

Splicing factors facilitate RNAi-directed silencing in fission yeast.

Heterochromatin formation at fission yeast centromeres is directed by RNA interference (RNAi). Noncoding transcripts derived from centromeric repeats are processed into small interfering RNAs (siRNAs) that direct the RNA-induced transcriptional silencing (RITS) effector complex to engage centromere transcripts, resulting in recruitment of the histone H3 lysine 9 methyltransferase Clr4, and henc...

Role of Aberrant Alternative Splicing in Cancer

Alternative splicing can alter genome sequence and as a consequence, many genes change to oncogenes. This event can also affect protein function and diversity. The growing number of study elucidate the pathological influence of impaired alternative splicing events on numerous disease including cancer. Here, we would like to highlight the significant role of alternative splicing in cancer biolog...

Tomato and Tobacco Phytoene Desaturase Gene Silencing by Virus-Induced Gene Silencing (VIGS) Technique

Background and Aims: Virus-Induced Gene Silencing (VIGS) is a virus vector technology that exploits antiviral defense mechanism. By infecting plants with recombinant viruses containing host genes inserted in the viral genome, VIGS achieves the RNA silencing process. The purpose of this study was to investigate the possibility of tomato (Lycopersicon esculentum Mill.) and tobacco (Nicotiana be...
