Analysis of the rabbit cardiac/slow twitch muscle sarcoplasmic reticulum calcium ATPase (SERCA2) gene promoter.

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 rabbit cardiac/slow twitch muscle sarcoplasmic reticulum (SR) Ca2+ ATPase (SERCA2) gene encodes a Ca2+ transport pump whose expression is regulated during skeletal/cardiac muscle development and by different pathophysiological states of the heart. This study was designed to delineate cis-acting regulatory elements involved in SERCA2 gene expression. A series of unidirectionally deleted fragments of the upstream 1,460 bp SERCA2 promoter were linked to the chloramphenicol acetyltransferase (CAT) reporter gene. Transient DNA transfection experiments performed with these constructs in C2C12 muscle cells and NIH3T3 fibroblasts revealed a 17 bp upstream promoter element (UPE) important for transcription of the SERCA2 gene in skeletal muscle cells. These studies have also identified a strong (muscle specific) negative regulatory region located upstream of nucleotide -658. Gel mobility shift and southwestern analyses using the 17 bp UPE have revealed a specific DNA binding complex referred to as Ca2+ ATPase promoter factor -1 (CaPF1). The binding factor has an approximate M(r) of 43 kDa. Comparison of CaPF1 with known transcription factors suggests that the CaPF1 complex may be a novel DNA-binding transcription factor which plays a role in SERCA2 gene regulation in vivo.
