"Objective: Cancer is a disease that gets serious attention in the medical world. This is due to the ever increasing number of patients and there has been no effective way to treat. Cancer cells have telomerase activity is relatively high compared to normal cells, so the cancer cells have the ability to continue to proliferate. Cancer cells undergo uncontrolled mitosis and have high telomerase activity compared to cells normal. Telomerase is an enzyme responsible for telomere length, a segment of DNA that is the tip of chromosomes in eukaryotic cells. Telomeres are associated with the process of aging and carcinogenesis. The purpose of this study was to determine the expression of telomerase in some cells such as breast cancer, cervical cancer, and lung cancer. Methods: The research method is experimental studies in several cancer cell cultures in the form of cell line. Cancer cells used were: HeLa (cervical cancer), MCF7 and T47D (breast cancer), WiDr (lung cancer), and Raji (lymphoma) with culture medium RPMI, DMEM, and M199. Vero cells is used (fibroblast cells) as a control (normal cells). Expression of telomerase enzyme was measured by the Immunohystochemistry (IHC) method. Results: The results showed that the cancer cells have activity/higher telomerase expression were highly significant (p<0.01) compared to normal cells (Vero cells). Similarly, the expression of telomerase in HeLa versus WiDr, WiDr versus T47D, T47D versus Raji, and Raji versus MCF7 also showed highly significant differences (p < 0.01). Telomerase expression between cancer cells that showed significant difference (HeLa cells versus Raji cells; HeLa cells versus MCF7 cell; T47D cells versus MCF7 cells) (p < 0.05). No significant difference was found in the group of HeLa cells versus T47D, WiDr versus Raji cells, and WiDr versus MCF7. Conclusions: It was concluded, that the cancer cells have telomerase expression of specific and different from each other, depending on the type of cell. T47D breast cancer cells have telomerase expression of the highest, followed by cervical cancer cells (HeLa). Lung cancer cells (WiDr) with cell lymphoma (Raji) has almost the same expression and both have lower expression.;"

Background: Colon cancer is one of the cancers that has an increasing incidence at this time, this happens because of high-fat consumption which causes absorption of carcinogenic compounds in the body and slows transport time to the intestine. Doxorubicin as a colon cancer drug has a weakness that is it can induce apoptosis and necrosis of healthy cells and cause toxicity to the liver, brain, kidney and heart, so an alternative treatment for colon cancer is needed. Spirulina platensis can be developed as an anticancer because of its availability in Indonesia’s ocean and has been proven to have many benefits.

Objective: to determine the phytochemical content and cytotoxic effects of Spirulina platensis extract on WiDr colon cancer cells. 

Methods: Maceration and extraction of Spirulina platensis using ethanol, ethyl acetate and n-hexane as solvents. The phytochemical components of the Spirulina platensis extract were analysed by means of phytochemical tests, and thin layer chromatography (TLC) tests. Analysis of the cytotoxic activity of ethyl acetate extract, n-hexane extract and ethanol extract on WiDr cells was carried out using the MTT assay method.

Results: The phytochemical components of the ethyl acetate extract and the ethanol extract of Spirulina platensis each contain secondary metabolites in the form of flavonoids, triterpenoids, steroids, alkaloids and glycosides. N-hexane extract of Spirulina platensis contains secondary metabolites in the form of triterpenoids, steroids and alkaloids. In the TLC test, seven phytochemical components were found in the n-hexane extract and six components in the ethanol and ethyl acetate extracts of Spirulina platensis.

Introduction: In Indonesia, Colorectal cancer is the second most common cancer in males and third most common in females. Like other types of cancer, the main treatment is a series of chemotherapies. On the other hand, it is known that a proportion of low-class” Indonesians, those who earns less than 1 million rupiah per month, in the economical aspect (58%) prefers the use of herbal medicine instead of conventional treatments. There are multiple factors which had influence the herbal preference such as marketing and social factors. Hence, the research and development of cancer drugs from herbal materials such as Sarang Semut (Myrmecodia pendans) is vital.

Methods: Sarang Semut (Myrmecodia pendans) was macerated by solvents N-Hexane, Ethyl Acetate, and Ethanol, producing three extracts N-Hexane (NHE), Ethyl Acetate (EAE), and Ethanol extracts (ETE). Each extract of Myrmecodia pendans was then analyzed through phytochemical tests and thin layer chromatography (TLC). In addition, the cytotoxicity effect of all three extracts were analyzed towards WiDr colon cancer cell using 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) Assay.

Results: Sarang Semut (Myrmecodia pendans) contains secondary metabolites Saponin, Flavonoid, Tannin, Triterpenoid, and Alkaloid. TLC analysis revealed that all three extracts of Myrmecodia pendans had six chemical compounds. MTT Assay revealed all three extracts of Myrmecodia pendans had no cytotoxic effect towards WiDr colon cancer cells.

Conclusion: Sarang Semut (Myrmecodia pendans) comprises several secondary metabolites which did not display cytotoxic effect towards WiDr colon cancer cell."
