Results from recent studies investigating alternative splicing during tissue development or cell differentiation.
Tissue / experimental conditions | Splicing targets or processes implicated in alternative splicing events | Recent review articles |
---|---|---|
Brain development / mouse cerebral cortex (RNA-seq), hippocampus (RNA-seq, microarrays) 13,31,139,140 | Endocytosis, vesicle mediated transport, small GTPases, cytoskeleton dynamics. | 76,141,142 |
Heart development / mouse ventricles, cardiomyocytes, cardiac fibroblasts (RNA-seq, microarrays) 5,11,80 | Cardiomyocytes: vesicular trafficking, membrane and cytoskeleton remodelling, ion channels, chromatin modifications. Fibroblasts: cell–cell contact, cell adhesion. | 79,143,144 |
Male germ cell development / mouse (RNA-seq)120,121 | Ralgps2, Bptf, Vapa4, Ezh2, Odf2, among others. | 145 |
T-cell activation / human Jurkat JSL1 cells PMA activated, primary human CD4+ T-cells (RNA-seq, microarrays)10,26,128,129 | Cell cycle regulation, cell signaling (BMP, CD40, NFKB, MAPK, RhoA pathways), vesicular trafficking, immune and inflammatory responses. Focus: LEF1 (exon 6), MKK7 (exon 2) | 146,147 |
Liver development / mouse hepatocytes and non-parenchymal cells (RNA-seq)12 | Actin-based processes, protein transport, splicing, chromatin modifications, cytoskeleton organization. | Not available to our knowledge |
Erythropoiesis / human erythroblasts from CD34+ cord blood progenitors (RNA-seq)137,138 | Cell cycle, chromatin function, RNA processing. Subset of transitions: PTCs and/or intron retention on RNA processing and spliceosome genes, indicating that splicing–NMD coupling may contribute to gene regulation. | 148 |
Erythropoiesis / mouse liver (RNA-seq)136 | Receptor activity, chromatin modifications, RNA processing, RNA binding, DNA repair and packaging. Focus: Ndel1. | 148 |
Myoblast differentiation / C2C12 cells (RNA-seq, microarrays) 14,149 | Cytoskeletal properties, actin binding, integrin signalling, cell junction. | Not available to our knowledge |
Smooth muscle cell de-differentiation / mouse primary cells from aorta and bladder (exon-junction arrays)15 | Actin cytoskeleton, non-motor actin binding protein. Differentiated cells: intron retentions lead to PTC and protein downregulation (RBPs, splicing factors, splicing regulatory kinases) | Not available to our knowledge |
