Aims: To evaluate anti-cancer activity of Asparagus racemosus (AR) leaf extract on UOK146, a renal cell carcinoma cell line, and explore its mechanism of action. Materials and Methods: Dried AR leaves were extracted with chloroform and dissolved in DMSO. This extract was applied to UOK146 and cell death was estimated by MTT assay. In addition PRCC-TFE3 fusion transcripts were detected by real time PCR. Results: Extract was found to be cytotoxic with an $IC_{50}$ of 0.9 mg/ml as estimated by dose response curve. Antitumor activity of the permissible doses of the extract was assessed by the down regulation of PRCC-TFE3 fusion transcript (38%) responsible for oncogenicity of the UOK146 cell line. No increment in the BAX, a proapoptotic marker level was observed. Conclusions: Evidence of antiproliferative effect, PRCC-TFE3 fusion transcript inhibition and static BAX level clearly indicate that AR extract provides or elicits an apoptosis independent anticancer effect on RCC cells by some specific mechanism of regulation.

Purpose: Anti-cancer activity evaluation of aqueous extract of CRUEL (herbomineral formulation) capsules on renal cell carcinoma cell lines, and exploration of mechanisms of cell death. Materials and Methods: To detect the cytotoxic dose concentration in renal cell carcinoma (RCC) cells, MTT assays were performed and morphological changes after treatment were observed by inverted microscopy. Drug effects against RCC cell lines were assessed with reference to cell cycle distribution (flow cytometry), anti-metastatic potential (wound healing assay) and autophagy(RT-PCR). Results: CRUEL showed anti-proliferative effects against RCC tumor cell lines with an IC50 value of ${\approx}4mg/mL$ in vitro., while inducing cell cycle arrest at S-phase of cell cycle and inhibiting wound healing. LC3 was found to be up-regulated after drug treatment in RT-PCR resulting in an autophagy mode of cell death. Conclusions: This study provides the experimental validation for antitumor activity of CRUEL.
