Riceberry rice bran is the part of rice that has been scrubbed out during coloring process. There are various health benefits with high protein content and antioxidant ability. The hydrolyzed rice bran consists of diverse peptides that provide various bioactive properties. This work aimed to study the effect of hydrolyzed riceberry rice bran extracted on colon cancer cell lines (HT- 29 and SW- 620) compared to normal cell (PCS- 291- 010). The MTT assay result showed that our extract has less cytotoxicity on normal cell (PCS-291-010, IC50 = 6,680.00 µg/ml) compared to the colon cancer cell lines and has more effect on metastatic cancer cell line (SW-620, IC50 = 5,492.31 µg /ml) than non-metastatic cancer cell line (HT-29, IC50 =6,040.76 µg/ml). According to the DNA fragmentation pattern analysis, the ladder pattern indicated that the rice bran extract can induce the apoptosis process in SW-620 cell line. Confirmed the pattern of apoptotic cell by AO/PI double stain test and quantified apoptotic cells by Annexin V. For the cell senescence analysis, SA-β-gal staining technique was performed at 24 h after treatments, HT-29 reached maximum senescence rate at 85.74% while SW-620 had only 17.23% of senescence. And a result of cell cycle analysis, HT-29 were decreased the number of cells in S, M/G2 phase, and increased the number of cells in G0/G1 phase. Furthermore > 50 kDa peptide fraction separated from HRBE has a potent anti-cancer cells (SW-620, IC50 = 4,908 µg/ml). In conclusion, the hydrolyzed riceberry rice bran extract can inhibit colon cancer cell lines with less effect on normal cell. The extracts could induce apoptosis process in metastatic cancer cell and induce senescence process in non-metastatic cancer cell. This observed information will be useful and applicable for medical research and colon cancer treatment in the future.

<P>Background: Breast cancer and human colon cancer are the most common types of cancer in females and males, respectively. Breast cancer is the most common type of cancer after lung and colon cancers. Natural products are an important source for drug discovery. Boesenbergia rotunda (L.) Mansf. is commonly known as finger root, belonging to the Zingiberaceae family. </P><P> Objective: The aim of this study to isolate some natural compounds from the rhizomes of B. rotunda (L.) Mansf., and to investigate their cytotoxicity against the human triple-negative breast cancer cell (MDA-MB-231) and HT-29 colon cancer cell lines. </P><P> Methods: The dried rhizomes of B. rotunda were extracted with methanol. The methanolic extract was further used for solvent-solvent extraction. Bioassay-guided extraction and isolation of the rhizomes of the B. rotunda exhibited cytotoxic properties of hexane and dichloromethane fractions. </P><P> Results: Six major chemical constituents, pinostrobin (1), pinostrobin chalcone (2), cardamonin (3), 4,5-dihydrokawain (4), pinocembrin (5), and alpinetin (6) were isolated from the rhizomes of the B. rotunda. All the chemical constituents were screened against the human triple-negative breast cancer cell (MDA-MB-231) and HT-29 colon cancer cell lines. The compound cardamonin (3) (IC50 = 5.62&#177;0.61 and 4.44&#177;0.66 &#181;g/mL) and pinostrobin chalcone (2), (IC50 = 20.42&#177;2.23 and 22.51&#177;0.42 μg/mL) were found to be potent natural cytotoxic compounds against MDA-MB-231 and HT-29 colon cancer cell lines, respectively. </P><P> Conclusion: Cardamonin (3) and pinostrobin chalcone (2) were found to be the most potential natural compounds against breast cancer cell line MDA-MB-231 and colon cancer HT-29 cell line.</P>

The synthesis of a wide variety of 3-trifluoromethyl-5,6-dihydro-[1,2,4]triazolo pyrazine derivatives, by the treatment of 3-trifluoromethyl-5,6,7,8-tetrahydro-[1,2,4]triazolo[4,3-α]pyrazine hydrochloride with an array of isocyanates in the presence of triethylamine, is reported. All the target compounds were synthesized in excellent yields under mild reaction conditions. The target molecules were effectively screened for their anti-cancer properties and the results are promising. The resultant compounds were assessed for their antiproliferative action against two human colon cancer cell lines (HCT-116 and HT-29 colon cancer cell lines). The IC50 range was estimated at 6.587 to 11.10 µM showing that compound RB7 had remarkable anticancer movement on HT-29. Additionally, it was discovered that RB7 incited the mitochondrial apoptotic pathway by up-regulating Bax and down-regulating Bcl2, eventually leading to the activation of Caspase 3 in HT-29 cells and initiation of cell death via the mitochondrial apoptotic pathway.

Summary This study provides new information on the cellular effects of 1,3,5-triazine nitrogen mustards with different peptide groups in DLD and Ht-29 human colon cancer cell lines. A novel series of 2,4,6-trisubstituted 1,3,5-triazine derivatives bearing 2-chloroethyl and oligopeptide moieties was designed and synthesized. The most cytotoxic derivative was triazine with an Ala-Ala-OMe substituent on the ring (compound 7b). This compound induced time- and dose-dependent cytotoxicity in the DLD-1 and HT-29 colon cancer cell lines. The triazine derivative furthermore induced apoptosis through intracellular signaling pathway attenuation. Compound 7b may be a candidate for further evaluation as a chemotherapeutic agent against colorectal cancer.

Aim: To investigate anti-proliferative effect of three types of Terengganu singgang extracts on colon cancer cell lines (HT-29, HCT-116, CT-26). Study Design: Experimental study. Place and Duration of Study: Central Laboratory, Tissue Culture Laboratory, Universiti Sultan Zainal Abidin, Terengganu between April 2019 and July 2019. Methodology: Samples comprised three types of singgang dish, which were prepared, cooked, and then extracted with distilled water and ethanol (EtOH) in different strengths, 50%, 70%, and 100%.These singgang samples were chub mackerel (ST), Indian mackerel (SK),and a control sample with no fish (SC). Extracts were analyzed for their anti-proliferative effect by MTT-based assay. Then, the morphological of cell apoptotic changes was observed using light inverted microscope. Results: Experimental assays showed that the SC sample extracted in 100% EtOH produced the highest yield (3.7%).The extract of ST in aqueous (0.27 (0.11)) yielded the most cytotoxic value, followed by extract SK in 100% EtOH (0.28 (0.10)) and extract SC in 50% EtOH (0.20 (0.08)). Then, the anti-proliferative effect was confirmed with morphological changes of cell which were characterized by cell shrinkage, membrane blebbing, and fragmentation of apoptotic bodies after 24, 48 and 72 hours of treatment. Conclusion: In conclusion, the ST extract showed the best anti-proliferative effect.

A panel of monoclonal antibodies (n=72 including controls) directed against lung cancer antigens was screened immunohistochemically against a panel of seven human lung cancer cell lines (including small cell carcinoma, squamous cell carcinoma, adenocarcinoma and mesothelioma), six human breast cancer cell lines and one human colon cancer cell line, The majority of the antibodies (n=42) reacted also with antigens present on breast and colon cancer cell lines, This cross reactivity especially between lung and breast cancer cell lines is not altogether unexpected since antigens common to breast and lung tissue including their neoplasms such as MUC1 antigen have been described, Our results indicate that epitopes shared by lung and breast cancers are probably more common than previously thought. The relevance for prognosis and therapy of these shared antigens, especially as disease markers in breast cancer, has to be investigated.
