Cancer is the most deadly disease that causes the serious health problems, physical disabilities, mortalities, and morbidities around the world. It is the second leading cause of death all over the world. Although great advancement have been made in the treatment of cancer progression, still significant deficiencies and room for improvement remain. Chemotherapy produced a number of undesired and toxic side effects. Natural therapies, such as the use of plant-derived products in the treatment of cancer, may reduce adverse and toxic side effects. However, many plants exist that have shown very promising anticancer activities in vitro and in vivo but their active anticancer principle have yet to be evaluated. Combined efforts of botanist, pharmacologist and chemists are required to find new lead anticancer constituent to fight disease. This review will help researchers in the finding of new bioactive molecules as it will focus on various plants evaluated for anticancer properties in vitro and in vivo.

Objectives : The present study was performed to clarify the antioxidant and anticancer effects of extract of stamens of Nelumbo nucifera and Kaempferol. Methods : Antioxidant effect was measured by DPPH-radical scavenging activity for electron donating ability (EDA), superoxide dismutase (SOD)-like activity for SOD and lipid peroxidation. Anticancer effect was assessed by MTT absorbance for cytotoxicity. Results : Vitamin E, Kaempferol and ethyl acetate extract of stamens of Nelumbo nucifera increased SOD-like activity and DPPH-radical scavenging activity dose-dependently. On the contrary, lipid peroxidation was time-dependently decreased. Furthermore, Kaempferol and ethyl acetate extract of stamens of Nelumbo nucifera significantly decreased the growth rate of C6 glioma cells. Conclusions : These results suggest that ethyl acetate extract of stamens of Nelumbo nucifera may be a putative antioxidant or anticancer substance.

Short-chain fatty acids (SCFAs), such as butyrate, propionate, and acetate produced by the gut microbiota have been implicated in physiological responses (defense mechanisms, immune responses, and cell metabolism) in the human body. In several types of cancers, SCFAs, especially butyrate, suppress tumor growth and cancer cell metastasis via the regulation of the cell cycle, autophagy, cancer-related signaling pathways, and cancer cell metabolism. In addition, combination treatment with SCFAs and anticancer drugs exhibits synergistic effects, increasing anticancer treatment efficiency and attenuating anticancer drug resistance. Therefore, in this review, we point out the importance of SCFAs and the mechanisms underlying their effects in cancer treatment and suggest using SCFA-producing microbes and SCFAs to increase therapeutic efficacy in several types of cancers.

The objective of this study was to investigate the anticancer effects of the extracts of oriental melon seeds. Various solvent extracts of oriental melon seeds were prepared and their anticancer effects were examined using in vitro MTT and CV assays. The anticancer effects of various extracts of oriental melon seeds were also examined in five human cancer cell lines including A549, AGS, HT-29, MCF-7 and HepG2. The ethanol extract of heated oriental melon seeds showed the potent cytotoxic effects especially against mouse hepatoma cell line(Hepa1c1c7), human hepatoma cell line(HepG2) and human breast cancer cell line(MCF-7). These data suggest that oriental melon seeds can be a promising anticancer agent against human liver and breast cancer.

In this study, the quality characteristics of kimchi, such as its salinity, pH, and acidity, were measured and compared, and the HT-29 human colon cancer cells were used to show the anticancer effects of kimchi. The kimchi samples used herein included standard kimchi (SK), turnip kimchi (TK), and turnip-powder-added kimchi (TPK). The measured pH and acidity of TK and TPK showed no significant differences with those of SK. Compared to SK and TK, TPK had higher DPPH scavenging activity and higher total flavonoid content, confirming its antioxidant activity. The cancer cell growth inhibition rates of TK and TPK were significantly higher than that of SK. In HT-29 cells treated with TPK, the mRNA expression of Bcl-xL, an anti-apoptosis-related gene, was lower, and the mRNA expressions of the apoptosis-related genes Bax, Bad, and caspase-9 were higher. TPK showed significantly higher levels of mRNA expressions for the cell-cycle-related genes p53 and p21 than the other samples, in addition to suppression effects on cancer cell proliferation. Compared to SK, TK and TPK suppressed the growth of colon cancer cells and showed higher anticancer effects. Therefore, it is shown that kimchi with added turnip powder had high anticancer effects.

The chlorophyll-related compound pheophorbide a (Pa) was successively purified from an edible red seaweed, Grateloupia elliptica, using silica, octadecyl silica column chromatography and reversed phase-high-performance liquid chromatography, as well as the cell cycle inhibitory and apoptotic effects of Pa being investigated in U87MG glioblastoma cells. The Pa exhibited strong anticancer effects in the absence of direct photo-irradiation against various cancer cell lines, including U87MG, SK-OV-3, and HeLa cells. Among the cancer cells, the strongest anticancer activity of Pa exhibited on U87MG cells with $IC_{50}$ values of 2.8 ${\mu}g/ml$. In addition, Pa specifically had cytostatic activity on glioblastoma cells rather than human umbilical vein endothelial cells. Analysis of the cell cycle distribution showed that Pa induced G0/G1 arrest of U87 MG cells. In addition, arrested cells induced late apoptosis and DNA degradation under dark condition. These results suggest that Pa isolated from G. elliptica is a potential glioblastoma-specific anticancer agent without side effects on normal cells.

Cancer stem cells (CSCs) are a rare subpopulation of cancer cells that exhibit stem cell-like characteristics, including self-renewal and differentiation in a multi-stage lineage state via symmetric or asymmetric division, causing tumor initiation, heterogeneity, progression, and recurrence and posing a major challenge to current anticancer therapy. Despite the importance of CSCs in carcinogenesis and cancer progression, currently available anticancer therapeutics have limitations for eradicating CSCs. Moreover, the efficacy and therapeutic windows of currently available anti-CSC agents are limited, suggesting the necessity to optimize and develop a novel anticancer agent targeting CSCs. Ginseng has been traditionally used for enhancing immunity and relieving fatigue. As ginseng's long history of use has demonstrated its safety, it has gained attention for its potential pharmacological properties, including anticancer effects. Several studies have identified the bioactive principles of ginseng, such as ginseng saponin (ginsenosides) and non-saponin compounds (e.g., polysaccharides, polyacetylenes, and phenolic compounds), and their pharmacological activities, including antioxidant, anticancer, antidiabetic, antifatigue, and neuroprotective effects. Notably, recent reports have shown the potential of ginseng-derived compounds as anti-CSC agents. This review investigates the biology of CSCs and efforts to utilize ginseng-derived components for cancer treatment targeting CSCs, highlighting their role in overcoming current therapeutic limitations.

Objective : In this study, we searched the experimental research about combined treatment of anticancer drug and herbal medicine for killing or inhibiting proliferation of Cancer cells searched in OASIS and KISS. This study aimed to analyze the experimental research paper about anticancer drug combined treatment with herbal medicine. Methods : We collected the research paper including killing or inhibiting proliferation of Cancer cells in OASIS and KISS using keyword anticancer drug with herbal medicine, tumor suppressor with herbal medicine, inhibition of Cancer with herbal medicine and combined treatment with herbal medicine. Assorting by cancer cells, we analyzed experimental results cancer cell viability, anticancer drug dosage, tumor weight and survival rate. Also, we checked the effects of herbal medicine on cancer and additive effect reducing side effect of anticancer drug. Results : Total 45 studies were selected. 38 studies reported combined treatment of anticancer drug and herbal medicine was more effective than only anticancer drug. The death of cancer cells was synergistically induced by the cotreatment of anticancer drug and herb extracts. The studies suggest that the cotreatment of anticancer drug and herb extracts could reduce side effect of anticancer drug. In addition, some studies reported cotreatment mechanism like apoptotic death signal processes. In combined treatment of anticancer drug and herb extracts, The expression of Fas/Fas L, Bax, Bcl2, Caspase-3 etc.. was markedly increased in cancer cells. Conclusions : Our results suggest that anticancer drug combined treatment with herbal medicine could be efficient for killing or inhibiting proliferation of cancer cells. However, this paper had some limitation as follows: First, collected studies have been published only for korean journal. Second, results of research and effects of combined treatment are not collected objectively. To solve these problems, more objective and balanced studies should be performed.

The object of this study was to observe anticancer and related immunomodulatory and anticachexic effects of Insamyangyoung-tang aqueous extracts (ISYYTe) on non-small cell lung carcinoma (squamous epithelial carcinoma), NCI-H520, xenograft Balb/c nu-nu nude mice. Changes on the tumor volume and weights, lymphatic organ(spleen and popliteal lymph node), serum interferon (IFN)-${\gamma}$ levels, splenocytes and peritoneal macrophage activities (NK cell activity), splenic tumor necrosis factor (TNF)-${\alpha}$, interleukin (IL)-$1{\beta}$ and IL-10 contents, splenic T-lymphocyte subsets (CD3+, CD4+ and CD8+) and TNF-${\alpha}+$ cells were observed with tumor mass and lymphatic organ histopathology to detect anticancer and immunomodulatory effects. In addition, changes on the body weights, epididymal fat weights and serum IL-6 levels were also detected with the thicknesses of deposited cervical brown adipose tissue and their mean diameters to monitor the tumor-related anticachexic effects. The results obtained in this study suggest that over 50 mg/kg of ISYYTe showed favorable anticancer effects on the NCI-H520 cell xenograft with immunomodulatory and anticachexic effects. However, detail mechanism studies should be conducted in future with the screening of the biological active compounds in this herb.
