Lidocaine could promote the cuproptosis through up-regulating the long noncoding RNA DNMBP-AS1 in Hep-2 cells.
Article in BMC cancer, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundLidocaine is a traditional local anesthetic, which has been reported to trigger apoptosis through the mitochondrial pathway, independent of death receptor signaling. Cuproptosis is a copper triggered mitochondrial cell death mode. In this study, we explored the biological effects of lidocaine on cuproptosis in Hep-2 cells and studied the relevant mechanisms.
methodsquantitative RT-PCR was used to measure the expression level of long noncoding RNA (IncRNA) DNMBP-AS1. DNMBP-AS1 siRNA (si-DNMBP-AS1) were transfected into Hep-2 cells to verify the roles of DNMBP-AS1 in cuproptosis. 24 h treatment with 20 nM elesclomol and 2 µM CuCl
resultsDNMBP-AS1 was significantly upregulated during cuproptosis in Hep-2 cells. The si-DNMBP-AS1 significantly increased the cell viability with nonactivated caspase-3, promoted the cell migration and suppress the cuproptosis. Lidocaine was cytotoxic to the Hep-2 cells in a dose- and time-dependent manner. Exposure to 10 µM of lidocaine for 24 h did not reduce the viability or activated the caspase-3, but significantly increased the expression of DNMBP-AS1, and promote the cuproptosis. Anymore, si-DNMBP-AS1 reversed the pro-cuproptosis function of lidocaine.
conclusionslidocaine was cytotoxic to Hep-2 cells in a time- and dose-dependent manner, promoted the cuproptosis through up-regulating DNMBP-AS1. The results of this study offered initial optimism that lidocaine could be used in an adjuvant or neoadjuvant fashion in cancer treatment.
