1 · What the graph read from it

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.

2 · The registry

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

Liver cancer stem cells (LCSCs) are responsible for the carcinogenesis, recurrence, metastasis and chemoresistance of hepatocellular carcinoma (HCC). This study aimed to explore the role of CCND1 (Cyclin D1), an oncogene in HCC, in regulating LCSC differentiation and to elucidate whether autophagy was involved in this process. The CCND1 mRNA level was examined by qRT-PCR. The protein levels of autophagy markers (Becin-1 and LC3II) were examined by western blot to evaluate autophagy level. CD133 was used as a LCSC marker and CD133 + cell percentage in HCC cells was detected by flow cytometry. Immunohistochemistry staining was performed to detect CD133 expression in SMMC-7721 cell-implanted tumor sections. The results showed that CCND1 expression was higher in HCC cell lines than that in normal hepatocyte L02 cells. Furthermore, CCND1 overexpression increased CD133 + cell percentage and protein levels of Becin-1 and LC3II in HepG2 and SMMC-7721 HCC cells. In contrast, CCND1 silencing exerted the opposite effect. Moreover, treatment with the autophagy activator rapamycin effectively abrogated the CCND1 silencing-reduced CD133 + cell percentage. Further in vivo assays demonstrated that CCND1 silencing decreased expression of CD133, Becin-1 and LC3II in xenograft tumors of SMMC-7721 cells. Taken together, CCND1 silencing suppresses LCSC differentiation through inhibiting autophagy.
