RPF2 mediates the CARM1‑MYCN axis to promote chemotherapy resistance in colorectal cancer cells.
Article in Oncology reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
Ribosome production factor 2 homolog (RPF2) plays an important role in the life processes of ribosomal biogenesis; however, the function and mechanism of RPF2 in tumors are unclear. The present study demonstrated that RPF2 expression is involved in chemoresistance in colorectal cancer (CRC) cells. The current study demonstrated that upregulation of RPF2 expression in CRC promoted resistance to chemotherapeutic agents in CRC cells, whereas knockdown of RPF2 leads to increased sensitivity of CRC to chemotherapy. In addition, it was found that overexpression of RPF2 led to an increase in ATP‑binding cassette (ABC)B1 expression in CRC cells; accordingly, inhibition of RPF2 reduced the level of ABCB1 in CRC cells, thus suggesting that ABCB1 may be a downstream factor of RPF2 in the promotion of chemotherapy resistance to CRC. The results also suggested that the expression of N‑myc proto‑oncogene protein (MYCN), an upstream regulator of ABCB1, was affected by RPF2 in CRC cells. In addition, it was also found that the downstream protein coactivator‑associated arginine methyltransferase 1 (CARM1) of RPF2 existed in direct binding to MYCN and this interaction was regulated by RPF2. The above results suggested that RPF2 is probably regulated ABCB1 expression in CRC through the CARM1‑MYCN pathway, thereby promoting CRC drug resistance.
