Brucea javanica oil emulsion alleviates cachexia induced by Lewis lung cancer cells in mice.

This study was conducted to evaluate the efficacy and possible mechanism of Brucea javanica oil emulsion (BJOE) on cachexia, by observing changes in related indexes in mice with cachexia and identifying the genes responsible based on gene chip analysis. In the BJOE treatment group, body weight loss, tumour growth and metastasis were found obviously inhibited, food and water intake had markedly increased, and survival time was significantly prolonged, as compared to the control group. Moreover, the BJOE witnessed improvement in body weight, prevention of tumour metastasis and overall increase in survival time, as compared to Indometacin (IND, the positive control medicine). It was also found that TNF-α and IL-6 in serum were significantly lower in both groups of BJOE and IND, than in the control group (p < .01). Based on the gene expression data, seven and six hub genes of BJOE and IND groups were found in the potential prognostic impacts networks, and three common genes comprising of Nmd3, Bcl2 and Nhp2l1 were screened. Thus, BJOE could reduce tumour growth and effectively alleviate cancer cachexia, due to inhibition of pro-inflammatory cytokines. Nmd3, Bcl2, Nhp2l1 may be important drug targets, establishing the role of BJOE in the treatment of lung cancer induced cachexia.
