Organs than stomach. Immunostaining of CTSE in normal esophagus (A), duodenum

Organs than stomach. Immunostaining of CTSE in normal esophagus (A), duodenum (B), small intestine (C), and colon (D) was demonstrated. (TIF)Figure S5 RT-PCR detecting MUC5AC, MUC6, CTSE,and GAPDH mRNA in the CTSE-transduced MKN-74, SH-10-TC, and MKN-1 cells, all of which are originally deficient in CTSE expression. These three gastric cell lines were infected with VSV-G get JI-101 pseudotyped MuLV-based retrovirus vectors expressing CTSE (+CTSE) or mock (+IP) to establish stable cell lines. NUGC4 was used as positive 25033180 control for the abovementioned four genes. (TIF)Table S1 Primer pairs, annealing temperatures (Tm), and product sizes (Length) for the 11 genes analyzed by RT-PCR.

The expression pathway from gene to protein is not always a simple one. One of the most common elaborations on the geneRtranscriptRprotein dogma is the presence of introns which break up otherwise contiguous coding sequences 1317923 within a genome, and which must be removed by cis-splicing of the gene transcript [1]. A rarer form of gene interruption is when gene exons are more distantly separated on the genome and/or encoded on opposite strands, dictating that individual exons are separately transcribed. In these cases, re-constitution of complete coding mRNAs requires a process of trans-splicing of the transcript exons. In organelles (plastids and mitochondria), the most prevalent form of RNA trans-splicing known occurs via discontinuous group I and II introns. These two intron families differ in the chemistry of their splicing reactions, but in both cases splicing involves the formation of a catalytic secondary structure by the intron sequence itself [2,3]. Thus, for discontinuous introns inter-molecular base pairing of the partial group I or II intron sequences regenerates the required catalytic function, enabling the trans-splicing of exons.
