Benefits of technology

[0029]In certain embodiments of the invention, the oncological disorder being treated or prevented is Squamous Cell Carcinoma. In certain other embodiments, the oncological disorder being treated or prevented is Basal Cell Carcinoma. Other embodiments of the invention, the oncological disorder being prevented is SCC, and the method prevents the pre-cancerous lesion actinic keratosis from progressing into SCC. In other embodiments, the oncological disorder being treated or prevented is melanoma.

Problems solved by technology

Cancer is presently one of the leading causes of death in developed nations and is a serious threat to modern society.
While increasingly successful, each of these treatments may cause numerous undesired side effects.
For example, surgery may result in pain, traumatic injury to healthy tissue, and scarring.
These standard treatments often are accompanied by adverse side effects, e.g., nausea, immune suppression, gastric ulceration and secondary tumorigenesis.
Due to its insolubility in water, limited solubility in lipids, and relatively large molecular weight, the efficiency of absorption of orally administered CoQ10 is poor.
In particular, the NCI cites three small studies on the use of CoQ10 as an adjuvant therapy after standard treatment in breast cancer patients, in which some patients appeared to be helped by the treatment, and reiterates that “weaknesses in study design and reporting, however, made it unclear if benefits were caused by the coenzyme Q10 or by something else.” The NCI specifies that “these studies had the following weaknesses: the studies were not randomized or controlled; the patients used other supplements in addition to coenzyme Q10; the patients received standard treatments before or during the coenzyme Q 10 therapy; and details were not reported for all patients in the studies.” The NCI further reports on “anecdotal reports that coenzyme Q10 has helped some cancer patients live longer, including patients with cancers of the pancreas, lung, colon, rectum and prostate,” but states that ‘the patients described in these reports, however, also received treatments other than coenzyme Q10 including chemotherapy, radiation therapy and surgery.”

Identification of CoQ10 as a MIM

[0281]In order to evaluate CoQ10 as a potential MIM, CoQ10 in oxidized form was exogenously added to a panel of cell lines, including both cancer cell lines and normal control cell lines, and the changes induced to the cellular microenvironment profile for each cell line in the panel were assessed. Changes to cell morphology / physiology, and to cell composition, including both mRNA and protein levels, were evaluated and compared for the diseased cells as compared to normal cells. The results of these experiments identified CoQ10 and, in particular, the oxidized form of CoQ10, as a MIM.

[0282]In a first set of experiments, changes to cell morphology / physiology were evaluated by examining the sensitivy and apoptotic response of cells to CoQ10. A panel of skin cell lines including a control cell lines (primary culture of keratinocytes and melanocytes) and several skin cancers cell lines (SK-MEL-28, a non-metastatic skin melanoma; SK-MEL-2, a metastatic ski...

Methods for Identifying Disease Relevant Processes and Biomarkers for Oncological Disorders

[0286]From the cell based assays in which cell lines were treated with a molecule of interest, the differences in treated vs non-treated cells is evaluated by mRNA arrays, protein antibody arrays, and 2D gel electrophoresis. The proteins identified from comparative sample analysis to be modulated by the MIM or Epi-shifter, are evaluated from a Systems Biology perspective with pathway analysis (Ingenuity IPA software) and a review of the known literature. Proteins identified as potential therapeutic or biomarker targets are submitted to confirmatory assays such as Western blot analysis, siRNA knock-down, or recombinant protein production and characterization methods.

Sensitivity of Cell Lines to CoQ10

[0342]A number of cell lines were tested for their sensitivity to Q10 after 24 hours of application by using a reagent (Nexin reagent) that contains a combination of two dyes, 7AAD and Annexin-V-PE. The 7AAD dye will enter into cells with permeabilized cell membranes; primarily those cells that are in late apoptosis. Annexin-V-PE is a dye that binds to Phosphotidyl serine, which is exposed on the outer surface of the plasma membrane in early apoptotic cells. The Nexin reagent thus can be used to differentiate between different populations of apoptotic cells in a flow cytometer.

[0343]PaCa2 cells showed an increase in both early and late apoptotic cells (between 5-10% of gated cells) with 50 μM Q10 and 100 μM Q10 after 24 hours of Q10 application. PC-3 cells also showed an increase in both early and late apoptotic population with 50 μM and 100 μM Q10, although the increase was less when compared to PaCa2 cells. MCF-7 and SK-MEL28 cells showed an incre...
