TIR-MAPT RNA expression. a Schematic representation of the MAPT gene and MAPT and TIR-MAPT mRNAs generated from it. A, C, D and E represent the hybridization sites of the primers designed for semi-quantitative PCR employed for the PCRs in b (Supplementary Table 2, online resource). The fragment of intron 12 that would remain upon retention is represented with colored stripes. b Representative images of agarose gels showing of semi-quantitative PCR results using total or cytoplasmic-enriched RNA of SH-SY5Y cells. Results showed the existence of RNA species from exon 11 to intron 12 where intron 11 was spliced out (PCR 5 and 6). Controls of the addition (RT+) or no addition of retrotranscriptase (RT−) were included. PCR 9 shows MAPT in which both intron 11 and 12 are spliced out. Detailed information of all semi-quantitative PCR combinations and amplicon sizes is provided in Supplementary Table 5, online resource. c Schematic representation of the MAPT gene including the hybridization sites of the oligos used for quantitative PCR. dTIR-MAPT RNA levels by qPCR in cytoplasmic-enriched fraction or whole extracts (total) of SH-SY5Y cells. e Comparison of TIR-MAPT level in SH-SY5Y cells and hippocampus and frontal lateral cortex of human brain. Graphs show means and SE of technical triplicates. f Percentage of brain samples having expression of MAPT or TIR-MAPT genes. Data are shown for three different regions within brains (see Supplementary Table 3, online resource). g Scatter dot blot of expression values of MAPT and TIR-MAPT genes in brain regions having TPM (transcripts per kilobase million) > 0. Number of samples f, g: cortex = 122; frontal cortex = 113; hippocampus = 98. Graphs represent mean and SEM. p values were calculated using a T test, ****p value ≤ 0.0001 Image collected and cropped by CiteAb from the following open publication (https://pubmed.ncbi.nlm.nih.gov/33934221), licensed under a CC-BY license.

W-Tau phosphorylation pattern. a Schematic representation of different Tau protein isoforms: full-length isoform with four repeats (R) and two insertions (N) (T42), full-length isoform with three repeats and no insertions (T30), the truncated by intron retention isoforms W-Tau with four repeats, two insertions and an extra peptide (W-T42) or with three repeats, no insertions and the extra peptide (W-T30); and the correspondent asparagine-endopeptidase-truncated isoforms (ET-T42 and ET-T30). Representation of the antibodies recognizing the Tau molecule at their corresponding epitopes: Antibodies recognize all isoforms of Tau (Tau12 on amino acids 6–18; Tau 5 on amino acids 210–241 and Tau 7.51 on amino acids 315–376) or specific against dephosphorylated Tau in residues Ser195, 198, 199 and 202 (Tau1), and phospho-Tau in residues Ser202/Thr205 (AT8), Thr231 (AT180), Ser404 (Tau404), Ser396 (Tau396) and Ser396/Ser404 (PHF1). W-Tau antibody recognizes the unique peptide present on W-Tau isoforms. b Samples from HEK293T cells transfected with the different isoforms were probed with different antibodies for phosphorylated and non-phosphorylated Tau. c Quantification of the data of different Tau epitopes with respect to total Tau measured with Tau 7.51 antibody, showing mean and SEM (n = 4). One-way ANOVA for multiple comparisons followed by a Kruskal–Wallis test was performed to compare each isoform and T42 full-length level of phosphorylation Image collected and cropped by CiteAb from the following open publication (https://pubmed.ncbi.nlm.nih.gov/33934221), licensed under a CC-BY license.

Background: Tau

Tau is a neuronal microtubule associated protein found predominantly on axons. The function of Tau is to promote tubulin polymerisation and stabilise microtubules, but it also serves to link certain signalling pathways to the cytoskeleton. Tau, in its hyperphosphorylated form, is the major component of paired helical filaments (PHF) and neurofibrillary lesions in Alzheimer's disease (AD) brain. Hyperphosphorylation impairs the microtubule binding function of Tau, resulting in the destabilisation of microtubules in AD brains, ultimately leading to the degeneration of the affected neurons. Hyperphosphorylated tau is also found in a range of other central nervous system disorders. Numerous serine/threonine kinases, including GSK3 beta, PKA, Cdk5, and casein kinase II can phosphorylate Tau.
