Abstract

Cervical cancer is one of leading causes of cancer death in women in the developing countries. The use of cisplatin as chemotherapy agent in cervical cancer is known to cause side effects and also resistance for long-term uses. One of the strategies to prevent cervical cancer based on combination agents is being developed. Leunca (Solanum nigrum L.) has been revealed to inhibit growth of human cancer cells. Therefore, it can be used in combination with cisplatin to reduce those side effects and prevent the occurrence of cell resistance. Ethanolic extract of Leunca Herb (ELH) and cisplatin were tested their cytotoxic effect on HeLa cervical cancer cell by using MTT assay to determine IC50 value. The combinationss of cisplatin-ELH were tested to determine the combination index (CI value).  The IC50 of ELH and cisplatin on HeLa cells were 227 µg/mL and 17 µM. rRespectively. Tthe study of combination resulted that almost all the index combinations were <0,9 showed  the effect of synergism combination. The Ooptimum concentration of combination was  1/8 IC50 cisplatin–1/8 IC50 ELH. The results indicated that ELH had a potency to be combination agent to enhance the activity of cisplatin on HeLa cervical cancer cells. Therefore, further study on its molecular mechanism needs to be explored.

Abstract

Solanum  nigrum  L.  or  Leunca  in  Indonesia  has  been  traditionally  used  as  a  herbal plant,  which  is  believed  to  have  anti-tumor  properties,  although  the  mechanism  for  the activity  remains  unknown.  The  resecarch  aim  to  examine  the  cytotoxic  effect  of  the ethanolic extract of Solanum nigrum on WiDr human colon cancer cells. In this study, we prepared an ethanol extract from herb of Solanum nigrum and investigated the mechanism involved  in  its  growth-inhibitory  effect  on  WiDr  human  colon  cancer  cells.  Herbs  of Solanum nigrum dry powder is extracted with 70% ethanol then added into the WiDr cell culture  in  96  wells  plate  in  various  concentration  :  50,  100,  250,  and  500  µg/ml. Cytotoxicity  of  the  Solanum  nigrum  ethanolic  extract    was  analyzed  with  MTT  assay  on WiDr human colon cancer cell lines. Results from the MTT assay showed WiDr cells was weakly  suppressed  in  the  presence of  the  extract.  The  result  of  the  assay  also  showed a very  close  correlation  between  the  Solanum  nigrum  extract  concentration  and  the surviving  cell  numbers  which  means  the  extract  caused  cell  death  in  a  dose-dependent fashion  in  WiDr  cancer  cells  with  the  IC50  of  359,23  µg/ml.  Collectively,  the  research suggest  further  studies  to  explore  other  chemopreventive possibilites  of  Solanum  nigrum ethanolic extract.Key words : colon cancer, MTT assay, cytotoxic, WiDr, Solanum nigrum
