Inhibiting Pyk2/Src expression by miR-23b-3p suppressed liver cancer stem cell function and hepatic carcinoma progression.

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
backgroundLiver cancer stem cells (LCSCs) are critical drivers of metastasis and chemoresistance in hepatocellular carcinoma (HCC). Proline-rich tyrosine kinase 2 (Pyk2) has been implicated in tumor progression, but its role in LCSC stemness and HCC malignancy remains unclear. This study explores the effects of Pyk2 and its regulation by miR-23b-3p on LCSC function and HCC progression.
methodsLCSCs were enriched from HepG2 and HCCLM3 cell lines, and Pyk2 knockdown was induced through siRNA transfection, with or without miR-23b-3p inhibitor co-transfection. We assessed cell proliferation, sphere formation, migration, invasion, and chemosensitivity. Stemness markers (Nanog, Oct4, Sox2, KLF4, and Bmi1) and Pyk2/Src signaling were analyzed via RT-qPCR, Western blotting, and immunohistochemistry. In vivo, tumor growth and Pyk2/Src expressions were evaluated in a BALB/c mouse xenograft model.
resultsPyk2 expression was significantly elevated in the identified LCSCs compared to the parental HCCs. Pyk2 knockdown significantly suppressed the LCSCs proliferation, sphere formation, migration, invasion, and enhanced chemosensitivity. The expression of stemness markers and miR-23b-3p was significantly inhibited in HCCLM3-LCSC
conclusionsInhibiting Pyk2/Src expression by miR-23b-3p suppressed LCSCs function and aggravated HCC progression.
