Lythrum salicaria L. (Lythraceae), a herbaceous plant growing widely in Iran, has been well known for many centuries for its astringent and styptic properties. A phytochemical investigation of this plant, based on spectroscopic analysis, identifi ed fourteen compounds: 5-hydroxypyrrolidin-2-one (1), umbelliferone-6-carboxylic acid (2), 3,3',4'-tri-O-methylellagic acid-4-O-β-D-(2"-acetyl)-glucopyranoside (3), 3,3',4'-tri-O-methylellagic acid-4-O-β- D-glucopyranoside (4), daucosterol (5), phytol (6), dodecanoic acid (7), oleanolic acid (8), 3,3',4'-tri-O-methylellagic acid (9), corosolic acid (10), β-sitosterol (11), peucedanin (12), buntansin (13), and erythrodiol (14). All compounds, except for 8 and 11, have been isolated from L. salicaria for the fi rst time. Cytotoxic activities of the compounds were examined against three cancerous cell lines, colon carcinoma (HT-29), leukemia (K-562), and breast ductal carcinoma (T47D), and Swiss mouse embryo fi broblast (NIH-3T3) cells using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and methotrexate as positive control. Compounds 5, 10, 11, and 14 were the most active against the HT-29 cell line with IC50 values of 192.7, 36.8, 38.2, and 12.8 μg/mL, respectively. Compounds 14, 11, 5, and 10 were 6.4, 2.8, 2.6, and 1.4 times, respectively, more selective than methotrexate. Compound 5 was the most active against the K-562 cell line (IC50 = 50.2 μg/mL), with a selectivity exceeding that of methotrexate 13.3 times. The results of the cytotoxic assay confi rmed that growth and proliferation of the cancer cell lines are predominantly infl uenced by triterpene derivatives and sterols of this plant

P. macrocarpa is a well known Indonesian medicinal plant which is traditionally claimed to have anticancer properties. To date, there are numerous cytotoxic studies conducted on crude extracts of this plant. However, there are limited informations available regarding cytotoxic activity of the compounds isolated from this plant. Thus, this study investigated cytotoxic activity of two benzophenones derivatives identified as 2,6,4'-trihydroxy-4-methoxybenzophenone (1) and 6,4'-dihydroxy-4-methoxybenzophenone-2-O-β-D-glucopyranoside (2) isolated from the ethyl acetate extract. Cytotoxic activities of these compounds were performed against human cervical carcinoma cell line (HeLa) and mouse embryonic fibroblast cell line (3T3) using MTT assay. The result showed that benzophenone (1)  exhibited low cytotoxic effect against HeLa and 3T3 cell lines with IC50 values of 132 µg/ml and 158 µg/ml, repectively while benzophenone (2) was non toxic against HeLa and 3T3 cell lines are because the IC50 is more than 250 µg/ml. These findings may sheds light on the actual properties of this plant.

Ergosterol peroxide (1) and ergosterol (2) were commonly isolated as the major compounds of Philippine mushrooms. Sterols 1 and 2 from the dichloromethane extract of Geastrum triplex and Termitomyces clypeatus, respectively, were evaluated for their cytotoxic activities against four human cancer cell lines, viz., breast cancer (MCF-7), colon cancer (HT-29), leukemia (THP-1), and small lung cell carcinoma (H69PR), and a human normal cell line, human dermal fibroblast-neonatal (HDFn), using the PrestoBlue® cell viability assay. Compounds 1 and 2 exhibited the strongest activities against HT-29 with IC50 values of 1.79 and 2.98 μg/mL, respectively, while Zeocin gave an IC50 of 4.89 μg/mL. These compounds also exhibited strong antiproliferative effects against MCF-7 with IC50 values of 4.13 for 1 and 4.20 μg/mL for compound 2, comparable to Zeocin with IC50 = 3.68 μg/mL. Only moderate cytotoxicity resulted when compounds 1 and 2 were tested against H69PR with IC50 values of 7.78 and 6.83 μg/mL, respectively, while Zeocin exhibited an IC50 of 9.81 μg/mL. Furthermore, compounds 1 and 2 showed no effects against THP-1 (IC50 > 100 μg/mL), while Zeocin showed an IC50 of 4.73 μg/mL. Although compounds 1 and 2 have been reported to exhibit different bioactivities in previous studies, the cancer cell lines tested and/or the polarities of the solvents for extraction varied. Therefore, comparisons of the cytotoxic activities of compounds 1 and 2 with earlier studies could not be made extensively.

In this study, two SiPcs have been selected and the photodynamic therapy potentials were evaluated of the Pcs. Synthesis of Axially 2-decyn-1-oxy disubstituted Es-SiPc-2 was newly synthesized by the reaction of SiPcCl2 with 2-decyn-1-ol in the presence of NaH in toluene. Furthermore, their nuclear imaging potentials were evaluated in human colon adenocarcinoma (HT-29) and human lung fibroblast cell (WI-38) cell lines. The uptake results have indicated that Es-SiPc labeled with [Formula: see text]I radionuclide ([Formula: see text]I-Es-SiPc) was approximately 2-fold higher in the HT-29 cell line than the WI-38 cell line. In other words, the target/non-target tissue ratio is defined as two in the HT-29/WI-38 cell lines. Besides, the uptake values of [Formula: see text]I-Es-SiPc were found to be higher than [Formula: see text]I-Es-SiPc-2. [Formula: see text]I-Es-SiPc and [Formula: see text]I-Es-SiPc-2 are promising for imaging or treating colon adenocarcinoma. In vitrophotodynamic therapy (PDT) studies have shown that both compounds are suitable and can be used in this field. Also, Es-SiPc has been shown to have higher phototoxicity than Es-SiPc-2.

The phorbol ester, phorbol 12-myristate 13-acetate (PMA), induces mucin secretion in the colonic tumor cell line T84 in a Ca(2+)-independent manner. To determine whether a specific protein kinase C (PKC) isoform is involved in colonic cells, we compared PMA-dependent mucin secretion by three human colonic tumor cell lines (T84, HT-29/A1, and LS 180) with the expression of PKC isoforms alpha, beta, delta, epsilon, and zeta, previously identified in human colon (L. A. Davidson, Y. H. Jiang, J. D. Derr, H. Aukema, J. R. Lupton, and R. S. Chapkin. Arch. Biochem. Biophys. 312:547-553, 1994). In each cell line PMA (10(-7) M) caused mucin secretion within 30 min. PMA-dependent mucin secretion was three to four times greater from HT-29/A1 and T84 cells than from LS 180 cells. All three-cell lines contained mRNA for PKC-alpha, PKC-epsilon, and PKC-zeta but not PKC-beta or -delta. Each cell line also expressed PKC-alpha, -epsilon, and -zeta protein. PKC-epsilon expression (mRNA and protein) was three to four times greater in HT-29/A1 and T84 cells than in LS 180 cells, correlating with PMA-responsive mucin secretion, whereas all cell lines contained similar levels of PKC-alpha mRNA and protein. When cells were stimulated by PMA, only PKC-epsilon was translocated from cytosol to membrane fractions early enough to stimulate mucin secretion. Because PKC-epsilon is also a Ca(2+)-independent isoform, it is likely to mediate mucin exocytosis in colonic cells.

Abstract Abstract 2904 Survival has improved dramatically in acute lymphoblastic leukemia (ALL), but further gains are unlikely using conventional chemotherapy alone. Several recently discovered, novel cytogenetic lesions with adverse prognostic impact, JAK2 activating mutations and CRLF2 rearrangements, occur in up to 15% of adult and pediatric ALL. These lesions are associated with activation of Jak2 and Stat5, and hold promise as targets for novel therapies affecting these signaling pathways. We performed in vitro testing of a novel small molecule Stat inhibitor, C188-9, in B-lineage ALL cell lines and patient samples with and without JAK2/CRLF2 alterations. C188-9 treatment for one hour at 10 μM inhibited Stat3 and Stat5 phosphorylation in ALL cell lines with JAK2 and CRLF2 alterations, but not in cell lines with wild-type JAK2 and CRLF2, as measured by phospho-flow cytometry (Fig. 1A). Only the cell lines with JAK2 and CRLF2 alterations demonstrated basal Stat5 phosphorylation on Western blot analysis, and this was inhibited by C188-9 treatment (Fig. 1B). C188-9 demonstrated cytotoxicity in ALL cell lines regardless of JAK2/CRLF2 status, with IC50s in the low micromolar concentration range (Fig. 1C). While C188-9 is undergoing investigation currently as a potent inhibitor of Stat3 in acute myeloid leukemia (AML), it also merits further investigation as an agent with Stat5 inhibitory activity and cytotoxicity in ALL. Figure 1. Effects of C188-9 in ALL cell lines. A.

Abstract Introduction Chronic Phase - Chronic Myeloid Leukemia (CP-CML) is a myeloproliferative disorder characterized by malignant proliferation of the granulocytic lineage without the arrest of cell differentiation. Tyrosine Kinase Inhibitors (TKI) have revolutionized CML treatment but several studies showed that a combination of TKI and Interferon alpha (IFNα) provides better clinical response. Myeloid Nuclear Differentiation Antigen (MNDA), which belongs to the hematopoietic interferon-inducible nuclear proteins with the 200-amino-acid repeat (HIN200) gene family, encodes a protein expressed in myeloid cells but whose function remains poorly understood. Because of its high expression in polymorphonuclear cells, its involvement in cell differentiation and apoptosis, and its induction by IFNα, we evaluated MNDA expression in CML cells and its modulation after incubation with IFNα. Material and methods We tested MNDA expression in several cell lines (K562, KCL22, LAMA84, TF1 and U937 (positive control)), in polymorphonuclear cells from healthy donors (HD-PMN, n=13) and in primary cells from patients with CP-CML at diagnosis (CP-CML; n=17). The relative expression of the MNDA transcript was analyzed using the 2-ΔΔCt method and was normalized to the endogenous reference gene GAPDH. HD-PMN were used as calibrator. We developed a multiparametric flow cytometry assay (CD45-V500/CD14-APC-H7/CD15-PerCpCy5.5/CD34-PC7/CD38-V450/MNDA-FITC) to detect MNDA protein in the different cell subsets, particularly in CD34+cells. Results As previously described, MNDA was poorly expressed in the K562 cell line. Similarly, mRNA was detected at low levels in two other CML cell lines (KCL22, LAMA84) and in TF1 cells, but at a high level in the U937 cell line, used as a positive control. In each cell line, the transcript expression was correlated to the protein level, as evaluated by flow cytometry (MFI ratio: 2.04±0.21, 2.36±0.24, 1.59±0.14, 1.88±0.11 and 8.77±0.54 for K562, KCL22, LAMA84, TF1 and U937, respectively (n=3)). In CP-CML primary cells, MNDA expression was greatly diminished as compared with HD-PMN in both mRNA (0.20±0.08 (n=17) vs. 1.32±0.21 (n=10); p=1.52x10-6) and protein (MFI ratio: 6.9±0.98 vs. 16.31±1.25, p=0.001). After having verified that IFNα (2000 U/ml, 16 hours) induced MNDA expression in HD mononuclear cells but not in PMN, we observed that induction of MNDA was moderate in CML cell lines K562 and LAMA84 (2-fold increase, n=3) whereas the level of MNDA mRNA was significantly increased in TF1 cells (28-fold increase, n=4). Induction in primary CML cells was variable (3/5 patients). Aiming to evaluate the expression of MNDA in leukemic stem cells (LSC), we first analyzed MNDA expression in CD34+ and CD34+/CD38- cells from HD. We observed that MNDA is down-regulated in healthy CD34+ and CD34+/CD38- cells compared to mature cells (mRNA: about 4 logs, protein: 8-10 fold lower, n=4), but we always detected a significant signal in CD34+cells (MFI ratio: 2.76±0.46, n=3). However, MNDA was not expressed by CML cells from the LSC compartment (n=4). This inhibition does not seem to be antagonized by nilotinib or IFNα (n=2). Discussion/Conclusion MNDA expression appears to be clearly down-regulated in CP-CML cells and dramatically so in the LSC compartment. In some patients, we observed sustained sensitivity to IFNα, but only in the compartment of more mature cells. This suggests early deregulation of MNDA expression which seems to be only partially dependant on differentiation. The mechanisms involved in this down-regulation remain to be elucidated but could be independent to TK activity of BCR-ABL protein and resistant to IFNα in the LSC compartment. This marked deregulation of MNDA in the LSC compartment is an additional argument in favor of intrinsic changes specific to primitive cells.

Background: Lactobacillus and Bifidobacterium species are among the probiotics discussed due to their anti-cancer effects in the treatment of colorectal and breast cancers in recent studies. The aim of this study was to investigate the anticancer effect of Familact, a commercial probiotic capsule containing seven bacterial strains (L. casei, L. acidophilus, L. rhamnosus, L. bulgaricus, B. breve, B. longum and Streptococcus thermophilus). Methods: Various cancer cell lines including Caco-2, HT-29, T47D and normal cell line L929 were treated with different concentrations of Familact. Using MTT assay, the cytotoxicity effect was investigated for each cell line and then flow cytometry analysis of apoptosis was evaluated. Results: Familact demonstrated inhibitory effects on the proliferation of all tested cancer cell lines in a dose-dependent manner. Although Familact augmented apoptotic cell death in HT-29 human cancer cells, it was less effective in the case of Caco-2 and T47D cells. Moreover, exposure to Familact showed moderate cytotoxicity towards L929 mouse fibroblast cells. Conclusion: Familact could be considered as a complementary therapy in the treatment of cancers.

Abstract Background: Currently it is unclear how in situ breast cancer progresses to invasive disease; therefore, a better understanding of the events that occur during the transition to invasive carcinoma is warranted. Here we have conducted a detailed molecular and cellular characterization of two, patient-derived, ductal carcinoma in situ (DCIS) cell lines, ETCC-006 and ETCC-010. Methods: Human DCIS cell lines, ETCC-006 and ETCC-010, were compared against a panel of cell lines including the immortalized, breast epithelial cell line, MCF10A, breast cancer cell lines, MCF7 and MDA-MB-231, and another DCIS line, MCF10DCIS.com. Cell morphology, hormone and HER2/ERBB2 receptor status, cell proliferation, survival, migration, anchorage-independent growth, indicators of EMT, cell signalling pathways and cell cycle proteins were examined using immunostaining, immunoblots, and quantitative, reverse transcriptase PCR (qRT-PCR), along with clonogenic, wound-closure and soft agar assays. RNA sequencing (RNAseq) was used to provide a transcriptomic profile. Results: ETCC-006 and ETCC-010 cells displayed notable differences to another DCIS cell line, MCF10DCIS.com, in terms of morphology, steroid-receptor/HER status and markers of EMT. The ETCC cell lines lack ER/PR and HER, form colonies in clonogenic assays, have migratory capacity and are capable of anchorage-independent growth. Despite being isogenic, less than 30% of differentially expressed transcripts overlapped between the two lines, with enrichment in receptor tyrosine kinase pathways and DNA replication/cell cycle programs. Conclusions: For the first time, we provide a molecular and cellular characterization of two, patient-derived DCIS cell lines, ETCC-006 and ETCC-010, facilitating future investigations into the molecular basis of DCIS to invasive ductal carcinoma transition.
