Induction of ovarian cancer cell apoptosis by 1,25-dihydroxyvitamin D3 through the down-regulation of telomerase. Jiang F, Bao J, Li P, Nicosia SV, Bai W. J Biol Chem. 2004 Dec 17;279(51):53213-21. Epub 2004 Oct 12. PMID: 15485861 doi: 10.1074/jbc.M410395200 Overall, the study suggests that the down-regulation of telomerase activity by 1,25(OH)2VD3 and the resulting cell death are important components of the response of OCa cells to 1,25(OH)2VD3-induced growth suppression. Progressive shortening of telomere associated with cell divisions limits the life span of normal cells and eventually leads to senescence. To become immortal, human cancers including OCa are invariably associated with activation of mechanism that maintains telomere length. Approximately 85-90% of cancers show reactivation of telomerase. The present study shows that telomerase in OCa cells is down-regulated by 1,25(OH)2VD3. Down-regulation of telomerase is due to decreased stability of hTERT mRNA rather than VDRE-mediated transcriptional repression through the putative VDRE present in the regulatory region of the hTERT gene. It is known that the inhibition of telomerase may lead to a phenotypic lag during which cells would continue to divide until the point at which the telomeres became critically short. This phenomenon may explain why the apoptotic induction by 1,25(OH)2VD3 needs the treatment for more than 6 days. As mentioned in the results, no detectable shortening of telomeric repeats was observed in parental OVCAR3 cells after 9 days of treatment with 1,25(OH)2VD3 (Fig. 4D). This is likely due to the fact that the short telomere (about 3 kb) in OVCAR3 cells is very close to the minimal length required for survival and that cells with detectably shorter telomere may have been selected against apoptosis. It has been shown that transformed human cells enter crisis once the terminal restriction fragment of the telomere reaches a length of about 4 kb. This is insufficient to protect chro

The effect of dietary omega-3 polyunsaturated fatty acids on T-lymphocyte subsets of patients with solid tumors. Gogos CA, Ginopoulos P, Zoumbos NC, Apostolidou E, Kalfarentzos F. Cancer Detect Prev. 1995;19(5):415-7. PMID: 7585727

Researchers say a combination of biomarkers may offer insights to build a noninvasive screening tool for pancreatic cancer as it related to new-onset diabetics.

Can sniffer dog detection take the place of traditional prostate cancer screening like immunized human antibody library ? It is still too early to draw a conclusion at present. Nobody knows how this sniffer dog detection technology can be applied to clinical use, or whether it can be widely promoted.

"Cancer lies dormant in all of us," he wrote in his new book, "Anticancer: A New Way of Life" (Viking, $25.95). "But our bodies are also equipped with a number of mechanisms that detect and keep such (defective) cells in check." Cancer rears its ugly head when things get out of balance, Servan-Schreiber said in an interview. And that can happen if the bad guys that promote the growth of cancer cells (tobacco, excessive alcohol, excessive sugar, hydrogenated fats, environmental pollutants) outnumber the good guys that support our natural defenses (cancer-fighting phytochemicals found in fruits, vegetables, herbs and teas; physical activity; and stress management techniques). But conventional treatment, while indispensable, focuses on a single target: destroying cancer cells. Doctors rarely address the other side: teaching patients how to fortify themselves using nutrition, exercise and stress-management techniques to create an inhospitable environment for cancer.

Dermatologists will soon get some high-tech help deciding which suspicious-looking moles should be removed and checked for melanoma.

In this video, Dr. Ramakant Deshpande explaining How does doctor decide Lung cancer treatment for different stages of Lung cancer. Lung cancer and its adversities can be lethal, if remains undiagnosed or left untreated. A multidisciplinary approach can successfully eliminate the cancer from lungs and patient may resume normal life after recovery, says Dr. Ramakant Dehspande, Chief of Thoracic Surgical Oncology, Asian Institute of Oncology. Lung cancer There are different sizes and stages of lung cancer, which are treated differently. Broadly, specialists categorize various types of lung cancer into two basic forms Non-small cell lung cancer and small cell lung cancer. The staging of lung cancer helps in deciding the severity of the disease, course of treatment, and chances of survival. Detection of cancer at an early stage increases the chances of successful treatment and full recovery of the patient. A small legion located in one area is known as the first stage; a little larger tumor is called stage 2; spread within the lungs is called stage 3, and if it spread to other parts then termed as stage 4.

Colon cancer has a little complex staging system as the stages advance with the spread of cancerous cells in the colon and other parts surrounding colon. Every professional has a great emphasis on the detection of the disease at an earlier stage because the timely recognition of the cancer accompanies higher chances of recovery and permanent cure.

Most breast cancer patients will receive surgery and then need to complete 4-6 cycles of postoperative adjuvant chemotherapy.
