Abstract

The development of cancer treatment were initiated by the existence of human’s effort to treat by applying certain materials which is mostly part(s) or extracts of plants, which are now adapted as traditional herbal medicine. The discovery of new drugs was based on intuition and empirical evidence. Thus, high luck factor was involved in a successful treatment with unguaranteed reproducibility. One example of drug being developed through conventional drug development is Taxol. Taxol is an extremely complex natural product and requires a bunch of hard work with high level of serendipity to be discovered as antitumor agent. Recently, rapid development in human biology and technology allow a change in drug discovery strategy by minimizing the luck factor. Targeted therapy has been a very promising strategy of drug development research, especially in cancer treatment. Although cancer has been known as a disease with very complex cellular and histo-pathophysiology, the abundance of studies on proteins, such as receptors and hormones, as the hallmarks of cancer allows us to explore carcinogenesis suppression further based on molecular targeted therapy. Kinases, one type of protein involved in signal transduction regulating cell growth and differentiation, could be the proteins that are proposed to be inhibited in suppressing tumor growth. An interesting example of the drug being discovered based on molecular modeling is the discovery of lapatinib as anti- cancer with specific target on HER-2 and EGFR to overcome the resistance of cancer to Herceptin caused by elevated level of EGFR expression.Keywords : targeted therapy, cancer, translational drug development

Abstract

Leunca (Solanum nigrum L.) has been proven to possess anticancer activity on some type of cancer cells. In vitro study of solamargine found in the herb showed cytotoxic effect against several breast cancer cell lines, such as T47D and MDA-MB-31. Hence, further study on its potential as a co-chemotherapeutic agent needs to be conducted, in order to overcome resistance problem commonly found in cancer chemotherapy. This study aimed to examine the cytotoxic activity of leunca herb ethanolic extract (LEE) alone and its combination with doxorubicin. Single and combinational treatment of LEE and doxorubicin on T47D breast cancer cells were done, and their viability representing cytotoxicity were analyzed by using MTT assay to determine the IC50 value and combination index (CI) to evaluate the combinational effect. Twenty four hours-treatment of LEE alone gave cytotoxicity activity showing a dose-dependent manner with the IC50 of 47 µg/ml, while combinational treatment showed that 4 µg/ml LEE was found to be synergist with 4 nM doxorubicin on T47D cells, with the optimum CI value of 0.59. This result shows that Solanum nigrum L. is potential to be proposed as doxorubicin co-chemotherapeutic agent against breast cancer. Further study on its molecular mechanism needs to be conducted.Key words: Solanum nigrum, doxorubicin, synergist, breast cancer

Abstract

Ficus septica Burm. f. ethanolic extract (FEE) shows cytotoxic effects on several cancer cell lines. Our research aimed to investigate the effect of FEE on apoptosis induction and p53 expression against carcinogenesis of 7,12-Dimethylbenz[a]anthracene (DMBA)-induced rat mammary.The research was conducted by comparing both apoptosis induction and p53 expression in DMBA-induced rats that were treated with FEE against control groups. Cells that undergo apoptosis were visualized by Double Staining method with acridine orange and ethidium bromide, while p53 expression was detected by IHC staining. Double staining results showed increased occurrence of apoptotic cells compared to the control groups. IHC staining of p53 did not show significant difference between treatment and control groups. However, FEE was able to repair morphology of cells undergoing carcinogenesis. Thus, we conclude that FEE has an anti-carcinogenic activity on DMBA-induced rat mammary through apoptosis induction without affecting p53 expression. Therefore, the ethanolic extract of Ficus Septica leaves is a potential chemo-preventive agent on breast cancer. Further study on its molecular mechanism needs to be explored.Keywords: Ficus septica, breast cancer, 7,12-Dimethylbenz[a]anthracene, carcinogenesis, apoptosis, p53

Abstract

Awar awar leaves which have not been optimally utilized in cancer treatment, are potential to be used in combination with doxorubicin (DOX), an agent used for chemotherapy. The aim of this experiment is to find out cytotoxic effect of awar-awar leaves ethanolic extract (ALE) and its combination with DOX towards breast cancer cells of T47D. ALE was prepared by macerating the dried-leaves powder with ethanol 70%. The cytotoxic effect of ALE toward breast cancer cells was tested employing MTT assay to the treatments both as a single agent and as a combination with doxorubicin (ALE DOX). The cytotoxicity was determined as IC50 value, while effectiveness of combination was measured by combination index (CI) to determine whether the effect is synergic, addictive, or antagonistic. Cytotoxic tests on single treatment ALE for a period of 24 hours resulted to a cytotoxic effect with IC so value of 13 µg/mL. ALE-DOX combination showed synergistic effect (CI < 1) on the concentration of 4.88 µg/mL (ALE) and 3.75 nM (DOX). The results showed that ALE is potential to be used as doxorubicin co-chemotherapeutic agent in breast cancer therapy.

Abstract

Sexually transmitted diseases (STDs) are diseases with a high prevalence rate. The World Health Organization (WHO) estimates that more than 1 million STDs are transmitted every day, those diseases are chlamydia, syphillis, trichomoniasis, ghonorroea, and virus caused diseases (hepatitis B virus, immunodeficiency virus, human papillomavirus, and herpes simplex virus). Early and accurate examination and detection are important to help with the healing and control of these diseases. One of the examination methods that could be used is using the laboratory diagnostic methods which contribute to 40% to 60% of the process of diagnosing a disease. Thus, early detection not only helps control the spread of STDs but also facilitates the healing process. However, in Indonesia there are obstacles in the examination of diseases due to several factors, such as inadequate surveillance system and limited examination facilities, so that most people are undiagnosed. Therefore, this review will discuss in more depth the development of diagnostics for sexually transmitted diseases in Indonesia and globally. Global development in diagnostics is very broad and diverse, in which many diagnostic techniques has already been established. The development of diagnostic techniques has progressed rapidly from simplex assays to multiplex and also computerized assays. Diagnostic techniques in Indonesia has also developed and some of the local kits have already been in the market showing that Indonesia is already moving towards production of local diagnostics.

Abstract

The investigation of mRNA development has gained substantial interest, particularly in the ex vivo and in vivo therapy. mRNA is widely used for the development of gene editing-based therapies and mRNA vaccines. The aim of this study was to optimize the medium and harvest time to increase plasmid DNA production as part of mRNA production. This study modified used a medium modification approach to achieve high density culture of Escherichia coli TOP10 pGEMT-N in batch cultivation method. Various media formulations were assessed, including LB; LB with phosphate buffer (K2HPO4 12.549 g/L and KH2PO4 2.31 g/L); LB with glycerol (50 g/L); LB with glycerol and phosphate buffer; LB with phosphate buffer, glycerol, glucose (15 g/L), and galactose (15 g/L). The effect of additional carbon sources and phosphate buffer on culture density was measured through OD600 and wet cell weight analysis. The highest OD600 and wet cell weight was observed when LB with glycerol and phosphate buffer was used, with OD600 of 4.78±0.14 and wet cell weight of 36.00±0.63 mg/ml. Plasmid DNA was subsequently isolated from these cultures following 5- and 7.5-hour incubation periods. The utilization of LB medium with glycerol and phosphate buffer resulted in a substantial increase in the volumetric concentration of plasmid DNA of 1,516.97±385.00 ng/ml after 5 hours of incubation. In conclusion, a remarkable enhancement in plasmid DNA volumetric yield within 5 hours was achieved by addition of glycerol and phosphate buffer to LB medium, leading to incubation period.
