Promising cytotoxic activity profile of fermented wheat germ extract (Avemar) in human cancer cell lines

Fermented wheat germ extract (FWGE) is currently used as nutrition supplement for cancer patients. Limited recent data suggest antiproliferative, antimetastatic and immunological effects which were at least in part exerted by two quinones, 2-methoxy benzoquinone and 2,6-dimethoxybenzquinone as ingredients of FWGE. These activity data prompted us to further evaluate the in vitro antiproliferative activity of FWGE alone or in combination with the commonly used cytotoxic drugs 5-FU, oxaliplatin or irinotecan in a broad spectrum of human tumor cell lines.

Characterizing the Efficacy of Fermented Wheat Germ Extract Against Ovarian Cancer and Defining the Genomic Basis of Its Activity

OBJECTIVE: Most women with advanced-stage epithelial ovarian cancer (OVCA) ultimately develop chemoresistant recurrent disease. Therefore, a great need to develop new, more active, and less toxic agents and/or to optimize the efficacy of existing agents exists.
METHODS:
In this study, we investigated the activity of Avemar, a natural, nontoxic, fermented wheat germ extract (FWGE), against a range of OVCA cell lines, both alone and in combination with cisplatin chemotherapy and delineated the molecular signaling pathways that underlie FWGE activity at a genome-wide level.

Promising cytotoxic activity profile of fermented wheat germ extract (Avemar®) in human cancer cell lines

Avemar is a fermented wheat germ extract with potent antimetastatic, antiproliferative and immunomodulatory activities. Chemically, it is a complex mixture of biologically active molecules including 2-methoxy-p-benzoquinone and 2,6-dimethoxy-p-benzoquinone which were supposed to be responsible for the main biological properties of Avemar. Despite its ubiquitous use as nutrition supplement for cancer patients in some countries only limited data are available on its activity in human cancer or in combination with chemotherapy.

Avemar, a nontoxic fermented wheat germ extract, attenuates the growth of sensitive and 5-FdUrd/Ara-C cross-resistant H9 human lymphoma cells through induction of apoptosis

Avemar (MSC) is a nontoxic fermented wheat germ extract, which has been shown to significantly improve the survival rate in patients suffering from various malignancies. We investigated its effects in sensitive and 5-FdUrd/Ara-C cross-resistant H9 human lymphoma cells. After 48 and 72 h of incubation, Avemar inhibited the growth of sensitive H9 cells with IC50 values of 290 and 200 microg/ml, whereas the growth of 5-FdUrd/Ara-C cross-resistant H9 cells was attenuated with IC50 values of 180 and 145 microg/ml, respectively.

Changes in The Kinase Expression Panel of K562 Human Leukemia After Avemar Treatment

Background: The positive effect of the wheat germ extract Avemar has already been proved in cancer. Compared to the control group significantly longer survival times were achieved in both in vivo experiments and clinical studies. Inhibition of cell growth was also detected in K562 human leukaemia cell line in vitro. Avemar given p.o.(3 g/kg) resulted in significant increase of the survival time compared to the control group (p<0.005 Mann-Whitney) in i.v. implanted K562 xenograft model, which was practically the same as the effect of Gleevec treatment.

Avemar, a nontoxic fermented wheat germ extract, induces apoptosis and inhibits ribonucleotide reductase in human HL-60 promyelocytic leukemia cells

Avemar (MSC) is a nontoxic fermented wheat germ extract demonstrated to significantly improve the survival rate in patients suffering from various malignancies. We investigated its effects in human HL-60 promyelocytic leukemia cells. After 24, 48, and 72 h of incubation, Avemar inhibited the growth of HL-60 cells with IC50 values of 400, 190, and 160 µg/ml, respectively. Incubation with MSC caused dose-dependent induction of apoptosis in up to 85% of tumor cells.

Cytotoxic activities of fermented wheat germ extract (Avemar) on human gastric carcinoma cells by induction of apoptosis

Background: The fermented wheat germ extract (code name:MSC, trade name: Avemar), is a complex mixture of biologically active molecules with potent anti-metastatic activities in various human malignancies. The objective of this study was to examine the in vitro cytotoxic activities of Avemar on 5 human gastric carcinoma cell lines and to test whether the mechanism involves induction of apoptosis.

Synergistic effect of Avemar on proinflammatory cytokine production and Ras-mediated cell activation

Macrophages activated by lipopolysaccharide and/or phorbol esters exhibited high sensitivity to Avemar, a fermented wheat germ extract. Avemar synergized with lipopolysaccharide and PMA in the induction of the transcription of cytokine genes and release of inflammatory cytokines. At higher concentrations the preparation had a significant negative effect on the proliferation and survival of activated myeloid cell types.

Immunologic and biochemical effects of the fermented wheat germ extract Avemar

Avemar (MSC) is a nontoxic fermented wheat germ extract demonstrated to have antitumor effects. Avemar has the potential to significantly improve the survival rate in patients suffering from malignant colon tumors. We studied its effects in the HT-29 human colon carcinoma cell line. Avemar had an inhibiting effect on colonies of HT-29 cells with an IC50 value of 118 lg/ml (7 days of incubation); this value could be decreased to 100 and 75 lg/ml in the presence of vitamin C.
