SULT2B1: a novel therapeutic target in colorectal cancer via modulation of AKT/PKM2-mediated glycolysis and proliferation.
Article in Journal of translational medicine, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
backgroundSulfotransferase family 2B member 1 (SULT2B1) is involved in regulating cell proliferation, migration and metabolism. However, there is still dispute regarding whether SULT2B1 acts as an oncogene or a suppressor, and the intrinsic mechanisms in modulating tumor progression need to be further elucidated.
methodsThis work aims to reveal the relationship among SULT2B1, AKT, PKM2 signaling and glycolytic pathways, and provided a theoretical basis for SULT2B1 as a potential therapeutic target for CRC.Bioinformatics methods, immunohistochemistry (IHC) and immunoblotting assays were performed to analyze the correlation between SULT2B1 and colorectal cancer (CRC). The effect of SULT2B1 on cell proliferation and migration were investigated by several phenotypic experiments in vitro and animal studies. The SULT2B1 interacting proteins were determined by immunofluorescence, immunoprecipitation and GST-pull down assays. Immunoblotting and mCherry-GFP-LC3 assays were performed to analysis autophagy. Chromatin immunoprecipitation (CHIP) assay was utilized to detect the effect of SULT2B1 in regulating transcription. Small molecule agonist/antagonist was used to modify protein activity and therefore analyze the mutual relationships.
resultsSULT2B1 is a predictive biomarker that is abnormally overexpressed in CRC tissues. Overexpression of SULT2B1 promoted cell proliferation and migration, while its knockout suppressed these processes. Furthermore, SULT2B1 could directly interact with the oncogene AKT and thereby enhance the activity of AKT-mTORC1 signaling. Furthermore, PKM2 was found to bind with SULT2B1, and regulated by SULT2B1 at both transcription and degradation levels. Moreover, blocking glycolysis attenuated the promoting effect of OE-SULT2B1.
conclusionSULT2B1 acts as an oncogene in CRC via modulating the AKT/PKM2 axis, therefore making it a promising diagnostic and therapeutic target for CRC.
