Although accumulating evidence suggests a chemopreventive role for folic acid in colon cancer, the regulation of this process in unknown. We hypothesize that supplemental folic acid exerts its chemopreventive role by inhibiting mucosal hyperproliferation, an event considered to be central to the initiation of carcinogenesis in the gastrointestinal tract. The present investigation examines the effect of supplemental folic acid on proliferation of Caco-2 and HCT-116 colon cancer cell lines. Furthermore, because certain tyrosine kinases, particularly epidermal growth factor receptor (EGFR), play a role in regulating cell proliferation, we also examined the folic acid-induced changes in tyrosine kinase activity and expression of EGFR. In Caco-2 and HCT-116 cells, maintained in RPMI 1640 medium containing 1 μg/ml folic acid, we observed that the supplemental folic acid inhibited proliferation in a dose-dependent manner. Pretreatment of HCT-116 and Caco-2 cell lines with supplemental folic acid (1.25 μg/ml) completely abrogated transforming growth factor-α (TGF-α)-induced proliferation in both cell lines. Tyrosine kinase activity and the relative concentration of EGFR were markedly diminished in both cell lines following a 24-h exposure to supplemental folic acid. The folic acid-induced inhibition of EGFR tyrosine kinase activity in colon cancer cell lines was also associated with a concomitant reduction in the relative concentration of the 14-kDa membrane-bound precursor form of TGF-α. In conclusion, our data suggest that supplemental folic acid is effective in reducing proliferation in two unrelated colon cancer cell lines and that EGFR tyrosine kinase appears to be involved in regulating this process.

Methanol extracts of five commercially available mushroom species (Phellinus linteus (Berk. et Curt) Teng, Cordyceps sinensis (Berk.) Sacc., Lentinus edodes (Berk.) Pegler, Coprinus comatus (O. F. M?ll.) Pers. and Ganoderma lucidum (Curtis) P. Karst), traditionally used as anticancer agents, were evaluated in vitro for their total phenol and flavonoid contents, cytotoxic and antimigratory activities and antioxidant/prooxidant effects on colon cancer cell lines (HCT-116 and SW-480). Spectrophotometric methods were used for the determination of total phenol content, flavonoid concentrations and DPPH activity of the extracts. Cytotoxic activity was measured by the MTT assay. The antimigratory activity of extracts was determined using the Transwell assay and immunofluorescence staining of ?-catenin. The prooxidant/antioxidant status was followed by measuring the superoxide anion radical (O2?-), nitrite and reduced glutathione (GSH) concentrations. Our results show that the highest phenolic and flavonoid content was found in P. linteus, and its DPPH-scavenging capacity was significantly higher than in other samples. The P. linteus extract significantly decreased cell viability of both tested cancer cell lines. All other extracts selectively inhibited SW-480 cell viability, but did not show significant cytotoxic activity. The mushroom extracts caused changes in the prooxidant/antioxidant status of cells, inducing oxidative stress. All extracts tested on HCT-116 cells demonstrated significant antimigratory effects, which correlated with increased production of O2?- and a reduced level of ?-catenin protein expression, while only P. linteus showed the same effect on SW-480 cells. The results of the present research indicate that the mushroom extracts causes oxidative stress which has a pronounced impact on the migratory status of colon cancer cell lines.

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.

Aim: To investigate anti-proliferative effect of fresh and pasteurized goat milk against 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 January 2020 and April 2020. Methodology: Samples comprised of two types goat milk, which were fresh and pasteurized in powder form. The samples were analysed for the anti-proliferative effect by MTT assay, and IC50 value was determined. Then, cell apoptotic changes were observed by light inverted microscope by 24, 48 and 72 hours. Results: Experimental data showed that the fresh sample produce the highest yield (9.40%) than the pasteurized sample (7.17%). The fresh sample yielded the most potent cytotoxic value (0.28 ± 0.03), followed by pasteurized sample with value IC50 0.32 ± 0.02 against HCT-116 cells. Then, the anti-proliferative effect was observed on cell apoptotic changes by reduction of cell volume, cell densed, and presence of fragmentation and apoptotic bodies at 24, 48 and 72 hours treatment. Conclusion: In conclusion, the fresh sample of goat milk yielded the potent anti-proliferative effect than pasteurized sample.

<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>

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.
