Here, we review the functions of alternative splicing events that have been experimentally determined. In human skin cancer, a splicing alteration in the protein TNC (tenascin C) pre-mRNA increases the number of tumor-promoting TNC-FL isoforms, resulting in cancer cell invasion and metastasis [24]. According to current studies, ncRNAs, especially miRNAs, lncRNAs and circRNAs, play crucial roles in regulating AS. Moreover, the lncRNA EGOT participates in the AS of ITPR1 pre-mRNA, sensitizing cancer cells to paclitaxel treatment. In HeLa cells, miR-7 inhibits the mRNA translation of the SF SRSF1 through partial complementation with its 3’UTR to downregulate SRSF1-mediated AS, suppressing cancer cell survival [59].

Moreover, the chromatin modification H3K36me3 (trimethylation on histone H3 thirty-sixth lysine), which can promote transcriptional activation, results in the recruitment of the SF SRSF1 to pre-mRNA to regulate AS [17]. Alternative splicing is a deviation from the conventional splicing as it removes introns in a different manner. These defintions explain the fundamental difference between RNA splicing and alternative splicing. The reduction in H3K36me3 promotes the expression of the CDH1 (cadherin 1) isoform with exon 8, acting as a biological marker in gastric cancer occurrence [113]. The impact of microRNAs on protein output. The lncRNA asFGFR2 has been verified to function through the recruitment of PRC2 (polycomb repressive complex 2, one of the two classes of polycomb-group proteins) and the histone demethylase KDM2a (lysine-specific demethylase 2A) to chromatin to form a special chromatin environment that disrupts the binding between MRG15 (MORF4-related gene on chromosome 15) with PTB (polypyrimidine tract binding protein).

Moreover, some miRNAs are able to stabilize mRNAs or promote translation by binding to the mRNA 5’UTRs [31]. 2019;20(5):1029. In addition, the lncRNA HOTAIR decreases the recruitment of multiple promoting molecules of SETD2 (SET domain-containing 2, the specific methyltransferase of H3K36) to downregulate SETD2 expression and phosphorylation, thus reducing SETD2-mediated H3K36me3, which can activate pre-mRNA transcription [111, 112]. For instance, miR-7 prevents the translation of SRSF1 mRNA and decreases SRSF1-mediated AS, repressing cancer cell survival. The interaction between ncRNAs and cis-acting elements can affect the selection of splice sites and/or the recruitment of SFs, thus regulating the expression of alternatively spliced isoforms in cancers. Splicing factor SRSF6 promotes hyperplasia of sensitized skin. A gene is first transcribed into a pre-messenger RNA (pre-mRNA), a copy of the genomic DNA containing both introns (destined to be removed during pre-mRNA processing) and exons (destined to be retained within the mRNA in order to code the protein sequence).

Resveratrol and pterostilbene as a microRNA-mediated chemopreventive and therapeutic strategy in prostate cancer. RNA splicing refers to a modification of the nascent pre-messenger RNA (pre-mRNA) transcript in which introns are removed and exons are joined prior to translation. The interaction of EZR-AS1 with Pol II and SMYD3 promotes the histone modification H3K4me3 (trimethylation of lysine 4 on histone H3) in transcription sites and facilitates pre-mRNA transcription [106, 107]. 2010;38(1):67–77. 4b). Consequently, ncRNA-mediated AS outcomes affect multiple cellular signaling pathways that promote or suppress cancer progression. NcRNAs can fine-tune the chromatin structure, which controls the recruitment of SFs to affect their interaction with pre-mRNAs in the AS process, changing splicing outcomes. For example, RBM24 binds an ISE to promote muscle-specific exon inclusion in cardiac and skeletal muscles [14]. Springer Nature. CircRNAs can sponge miRNAs through base pairing to protect their target mRNAs. CAS  Cell. 5b). 2015;15:954. 2019;25(22):2763–75. LncRNAs are more than 200 nucleotides in length with poorly conserved properties, and their functions include acting as molecular scaffolds in various biological processes, disturbing nearby pre-mRNA transcription, forming RNA–RNA duplexes with pre-mRNA molecules or miRNAs as posttranscriptional regulators, promoting specific protein activities, and recruiting or inhibiting regulatory proteins in multifarious transcriptional, posttranscriptional or posttranslational manners.

On the one hand, snRNAs associate with proteins to form snRNPs and play snRNP-mediated regulatory roles. 2018;46(5):2169–84. Moreover, the snRNA U1, which recognizes transcriptome-wide 5′ splice sites through base pairing [53], can bind to extensive U1-targeted pre-mRNAs to promote intron exclusion. During splicing, introns are removed and exons are joined together. MiRNAs can inhibit SF expression through complete or partial complementation with the target mRNA of an SF, degradation of the mRNA or the downregulation of mRNA translation as a result [54, 55] (Fig. miR-193a-5p promotes pancreatic cancer cell metastasis through SRSF6-mediated alternative splicing of OGDHL and ECM1.

NcRNAs, which occupy almost 60% of the transcriptional output in human cells [25], are RNAs that do not encode proteins. In addition to the inhibitory function described above, ncRNAs can also act as “decoys” to promote the binding of SFs to targeted pre-mRNAs. All data generated or analyzed during this study are included in this published article. Alternative splicing in cancers: from aberrant regulation to new therapeutics. Sander S, Bullinger L, Klapproth K, Fiedler K, Kestler HA, Barth TF, et al. For nuclear-encoded genes, splicing takes place within the nucleus either during or immediately after transcription. Defects in AS influence the occurrence and development of many diseases, including cancers, and are frequently found to participate in various aspects of cancer biology, such as promoting invasion, metastasis, apoptosis resistance and drug resistance. The spliceosome is assembled from five snRNPs (small nuclear ribonucleoproteins), namely, U1, U2, U4, U5, U6 and over 300 non-snRNP proteins.
