A new cancer/testis long noncoding RNA, the OTP-AS1 RNA.
Article in Scientific reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The orthopedia homeobox (OTP) gene encodes a homeodomain-containing transcription factor involved in brain development. OTP is mapped to human chromosome 5q14.1. Earlier we described transcription in the second intron of this gene in wide variety of tumors, but among normal tissues only in testis. In GeneBank these transcripts are represented by several 300-400 nucleotide long AI267901-like ESTs. We assumed that the AI267901-like ESTs belonged to the longer transcript(s). We used the Rapid Amplification of cDNA Ends (RACE) approach and other methods to find the full-length transcript. The transcript we found was a 2436 nucleotide polyadenylated sequence in antisense to OTP gene. The corresponding gene consisted of two exons separated by an intron of 2961 bp. The first exon was found to be 91 bp long and located in the third exon of OTP. The second exon was 2345 bp long and located in the second intron of OTP. We have shown the expression of this gene in many human tumors but as few as a single sample of normal testis. The transcript lacked significant ORFs suggesting that we discovered a new antisense cancer/testis (CT) sequence OTP-AS1 (OTP-antisense RNA 1), which belongs to the class of long noncoding RNAs (lncRNAs). According to our findings we assume that OTP-AS1 and OTP genes may be a CT-coding gene/CT-ncRNA pair, or sense-antisense gene pair involved in regulatory interactions.
