    The example of <t>HRM</t> analysis in patients 385 and 419 (exon 39). 1 Detection of mutations by HRM. The green curve in the diagram corresponds to the <t>PCR</t> fragment carrying the nonsense mutation c.11172G > A (p.Trp3724X) in patient 385. The red curve refers to the PCR fragment carrying the likely pathogenic substitution c.11248C > G (p.Arg3750Gly) in patient 419. The rest of fragments with blue curves are wild type samples (patients without sequence changes). 2, 3 Confirmation of mutations by direct sequencing in patient 385 (number 2) and patient 419 (number 3). Both sequences are in reverse direction. The letter A corresponds to the mutated sequence; B is the wild type.

    TaKaRa polymerase chain reaction pcr fragments
    Ectopically expressed intronless <t>TSG101</t> gene (cDNA) is spliced and generates equivalent product as the endogenous aberrant mRNA in cancer cells. ( A ) The structure of the TSG101 mRNA. Red line and triangles indicate the postulated mRNA re-splicing via activated alternative 5′ and 3′ splice sites. Blue triangle indicates the PTC (1112–1114) generated by the postulated splicing. Black flags indicate the open reading frame (ORF; 127–1296). The positions of the <t>PCR</t> primers (P1–P4, P7–P10) are shown. ( B ) Using normal cells (HMEC) and cancer cells (MCF-7), endogenous TSG101 mRNAs were analyzed by RT-PCR (RT) and the genomic DNA was analyzed by PCR (Ge) with primer sets (P1–P4, P7–P10) annealed to the indicated exons. The black and red arrowheads denote the full-length and major aberrant mRNAs, respectively ( Figure 1 ). ( C ) The structures of three reporter TSG101-EGFP plasmids (see (A) for the red and blue triangles). The postulated splicing-dependent EGFP expression of these plasmids is indicated with (−) and (+). The positions of the PCR primer sets (P1–P5, P3–P6) are shown. ( D ) Cancer cells (MCF-7) were transfected with the indicated TSG101-EGFP reporter plasmids and the EGFP expression was analyzed by fluorescence microscopy. ( E ) These ectopically expressed TSG101-EGFP transcripts were analyzed by RT-PCR. The black and red arrowheads indicate the unspliced and spliced products via the alternative splice sites, respectively. Two minor spliced products (indicated with * and **) were generated from different alternative 3′ splice sites, i.e. Δ190–776 (587-nt deletion) and Δ190–1236 (1047-nt deletion), respectively.

    Ectopically expressed intronless FHIT gene (cDNA) is spliced, generating a product equivalent to the endogenous aberrant mRNA in cancer cells. ( A ) Schematic representation of the FHIT pre-mRNA and the observed aberrant splicing in cancer cells (red line). The aligned sequences of the normal (full-length) and aberrant FHIT mRNAs reveal the skipping of exon 3 to exon 6.

The full-length mRNA (black arrowhead) and aberrantly spliced mRNA (red arrowhead) are indicated. Black flags indicate the ORF (372–815) and the red line indicates the postulated mRNA re-splicing that skips the whole exon 3 to exon 6 region.

    Detection of the lariat RNA consisting of only exons demonstrates the re-splicing of the endogenous TSG101 mRNA. ( A ) Schematic representation of the two postulated pathways leading to the generation of the aberrant mRNA, i.e. a conventional one-step direct aberrant splicing (right) and the proposed two-step process, including the re-splicing of the constitutively spliced mRNA (left). The pre-mRNA [1] and specific splicing products [2–5] from these two pathways were analyzed by RT-PCR with the indicated primers (arrows). ( B ) Detection of the specific splicing products [2–5] by RT-PCR using RNase R-digested (+) or RNase R-undigested (−) endogenous total RNA. The detected RT-PCR signals in the RNase R-digested sample (containing no linear RNAs) indicates an RNA species with either a 5′–2′ lariat or a 5′–3′ circular structure. However, the latter case was ruled out by the identification of a 5′–2′ branched structure ( Figure 4 A). Primers P19, P20, P21 and P22 anneal to introns 6, 7, 7 and 8, respectively. Primers P13/14 and P15/16 anneal to introns 7 and 8, respectively. Primers P11, P12, P17 and P18 anneal to exons 8, 10, 5 and 8, respectively. We used exactly the same PCR cycle numbers to amplify all these RNAs ( Supplementary Materials and Methods ).
