Mitochondria and Cancer: Past, Present, and Future
Email: alimonti. The phosphatase and tensin homolog located on chromosome ten, PTEN, is one of the most commonly mutated tumor suppressor genes TSGs in human cancer [ 1 — 3 ]. There is no current evidence that mutations in PTEN account for a substantial proportion of familial breast cancer in the absence of Cowden syndrome [ 6 ]. Our paper, in the last month's issue of Nature Genetics provides additional evidence of the role of PTEN dose in breast cancer susceptibility, braking current dogmas regarding the development of cancer and opening to novel clinical and therapeutic implications [ 10 ]. For students that, like myself, attended medical school in the mid s, it was often unclear, with few exceptions, how novel discoveries in cancer genetics could impact on the clinic. At that time, the mechanism driving tumor initiation and cancer progression was reasonably clear. One of the first lessons in the class of cancer genetics included the explanation and discussion of the well known Knudson's two-hit model of tumorigenesis [ 11 ].
Breast cancer is the most common cancer among females in developed countries. Strategies such as early detection by breast cancer screening can reduce the burden of disease but have disadvantages including overdiagnosis and increased cost. Stratification of women according to the risk of developing breast cancer, based on genetic and lifestyle risk factors, could improve risk-reduction and screening strategies by targeting those most likely to benefit. Breast cancer risk is partly determined by genetic factors including rare pathogenic variants in susceptibility genes and common low-risk variants. Other risk factors include alcohol use, smoking, reproductive factors, hormonal factors, family history, mammographic density, BMI, and body height.

Family Cancer Syndromes

Sometimes, certain types of cancer seem to run in some families. In some cases, this might be because family members share certain behaviors or exposures that increase cancer risk, such as such as smoking. Cancer risk might also be affected by other factors, like obesity, that tend to run in some families. But in some cases the cancer is caused by an abnormal gene that is being passed along from generation to generation. Although this is often referred to as inherited cancer, what is inherited is the abnormal gene that can lead to cancer, not the cancer itself. This information is about those cancers. Cancer is a disease in which cells grow out of control.

PTEN breast cancer susceptibility: a matter of dose
Breast cancer susceptibilty genes are inherited factors that cause a genetic predisposition to breast cancer, meaning that mutations in these genes increase the risk of developing breast cancer. Predisposing factors are divided into three classes according to the associated breast cancer risk: high-, intermediate-, and low- penetrance Modifier Loci genes in addition to a few genes with uncertain penetrance. Dysfunction in multiple low-penetrance genes can also accumulate to a higher predisposition.
A hereditary predisposition to breast cancer significantly influences screening and follow-up recommendations for high-risk women. Prediction models suggest that there are unlikely to be additional yet to be identified high-penetrance genes. Investigation of common, low-penetrance alleles contributing to risk in a polygenic fashion has yielded a small number of suggestive single-nucleotide polymorphisms SNPs , but the contributive risk of an individual SNP is quite small.

Breast Cancer Susceptibility—Towards Individualised Risk Prediction
Она пыталась не думать о Дэвиде, но безуспешно. С каждым завыванием сирены слова Хейла эхом отдавались в ее мозгу: Я сожалею о Дэвиде Беккере. Сьюзан казалось, что она сходит с ума. Она уже готова была выскочить из комнаты, когда Стратмор наконец повернул рубильник и вырубил электропитание. В одно мгновение в шифровалке установилась полная тишина.
