former smokers

A new study has found that a derivative of vitamin A may help cut down the risk of lung cancer in former smokers by reducing the growth of lung cells. Former smokers remain at elevated risk for lung cancer as lung cells that were damaged during years of smoking may continue to grow and evolve into cancer even after a person has quit smoking. Lung cancer is the most common create of cancer-related death in both men and women. It kills 1.3 million people worldwide annually. Researchers from the University of Texas studied about 225 former heavy smokers and open that retonic acid a vitamin A derivative reduced lung cell growth in them reported health portal Medical News Today. Vitamin A can be found in cheese eggs oily look for such as mackerel milk fortified margarine and yogurt. This entry was posted on Thursday. November 1st. 2007 at 4:25 amand is filed under.

Monday was global Psoriasis Awareness Day which lead me to research for today’s affix. Psoriasis is an autoimmune disease that causes redness itching scaling and inflammation of the climb and inflammation of the joints a condition known as psoriatic arthritis. Psoriatic arthritis affects up to 15% of populate with psoriasis. Psoriasis is not contagious but it is a chronic condition which can appear as localized red scaly patches or can cover the entire body. Recent studies undergo shown that smoking increases the risk of psoriasis. In a inform published in the American Journal of Medicine one such chew over reflected the undergo of 78,500 nurses from 15 states that participated in the Nurses Health chew over II. This assort provided baseline health information in 1989 and updates for the next 14 years. During that measure the researchers documented 887 cases of psoriasis. In order to measure the lifetime smoking exposure the researchers assigned a “pack-year” value to their analysis. A pack-year is calculated as the number of packs smoked per day times the be of years the person has been a smoker. Researchers discovered that when compared to those who have never smoked current smokers have a 78% higher risk of psoriasis and for former smokers the risk is 37% higher. They also open that the more a person smoked the risk was change surface higher. Specifically they found that the assay for those with 1-10 pack-years was 20% higher. 11-20 pack-years was 60% higher and was more than double for those with 21 or more pack-years. They also open that the assay of psoriasis due to exposure to second transfer smoke during pregnancy or childhood was also higher by nearly to 20%. Cigarettes are known to include over 4000 chemicals of which 51 have been determined to be carcinogenic. They scientists accept that these toxins affect the move of the immune system that is associated with psoriasis. There was also some good news. The risk to former smokers decreases to nearly that of non-smokers 20 years after quitting. So if you are a smoker you can reduce your assay of psoriasis and psoriatic arthritis as well as a host of other diseases substantially by quitting.

Research recently published in BMC Genomics could back up explain why smokers who depart comfort undergo an increased assay of lung cancer compared to those who have never smoked. Using a technique called SAGE (serial analysis of gene expression). Wan L. Lam and Stephen Lam from the BC Cancer Agency studied samples from the lungs of smokers former smokers and non-smokers to determine patterns of gene activity. The aggroup investigated genes that are switched on by smoking by studying changes in gene activity. They open that although some of the genetic changes were reversible after quitting some were not. Genes identified as permanently changed appear to be functionally diverse. Several DNA ameliorate genes are irrevocably damaged by smoking and genes that back up to prevent the development of lung cancer are switched off in smokers. Changes in genes involved in airway repair and regeneration were studied in depth and these fell into one of three categories following cessation of smoking: reversible partially reversible and irreversible. Over-expression of TFF3 a gene involved in mucus structure and CABYR which may compete a role in bronchial epithelium ciliary action are reversible. MUC5AC which is a mucin gene experiences partially reversible changes in gene activity. Irreversible under-expression occurs in GSK3B which regulates COX2. Inhibition of GSK3B induces the expression of COX2 one of many genes involved in lung cancer development. It plays a role in cellular proliferation migration and invasiveness. Under-expression of GSK3B in both smokers and former smokers may contribute to development of lung cancer regardless of current smoking status. The aggroup’s findings were tested against a second cohort of current former and non-smokers. Smoking accounts for 85 percent of lung cancers and half of newly diagnosed lung cancer patients are former smokers. These new findings provide insight into why those who quit smoking are still at risk.

Even years after quitting former smokers still have an increased assay of lung cancer – and now Canadian scientists accept they experience why. It appears that though most smoking alter is repaired over measure the habit appears to permanently alter the activity of key genes. Dr. Stephen Lam head of the B. C. Cancer Agency’s lung tumour group says the findings may inform why 50 per cent of Canadian patients with newly diagnosed lung cancer are former smokers. Researchers from the B. C. Cancer Agency writing in the journal BMC Genomics looked at the lung create from raw material of 24 current former and non-smokers. Using a technique called serial analysis of gene expression (SAGE) they identified change state to 600 genes that were differentially expressed between current and non-smokers. Only about a fifth of the genes in a cell are switched on at any given time but environmental factors such as smoking lead to changes in gene activity. Of the 600 genes identified changes in almost one third of them are irreversible in former smokers the researchers found. Specifically some DNA repair genes are irreversibly damaged by smoking. Smoking also switched off genes that help combat lung cancer development. 08/29/07. 04:13:40 pm by GEN-ERIC. 47 views.

Montreal - Smoking tobacco is no longer considered sexy but it may be a permanent turn on for some genes. investigate published today in the online open find journal BMC Genomics could back up explain why former smokers are comfort more susceptible to lung cancer than those who have never smoked. A Canadian aggroup led by Wan L Lam and Stephen Lam from the BC Cancer Agency took samples from the lungs of 24 current and former smokers as come up as from non-smokers who undergo never smoked. They used these lung samples to create libraries using a technique called serial analysis of gene expression (SAGE) which helps to identify patterns of gene activity. Only about a fifth of the genes in a cell are switched on at any given time but environmental changes such as smoking lead to changes in gene activity. The researchers found changes that were irreversible and some changes that were reversed by stopping smoking. The reversible genes were particularly involved in xenobiotic functions (managing chemicals not produced in the be) nucleotide metabolism and mucus secretion. Some DNA ameliorate genes are irreversibly damaged by smoking and smoking also switched off genes that help combat lung cancer development. The researchers identified a be of genes not previously associated with smoking that are switched on in active smokers. One example is CABYR a gene involved in helping sperm to go and associated with hit tumours which may have a ciliary answer. The team also further investigated changes in genes involved in airway ameliorate and regeneration and within this assort identified genes that cut into three categories following cessation of smoking: reversible (TFF3 encoding a structural component of mucus; CABYR in it’s newly discovered bronchial role) partially reversible (MUC5AC a mucin gene) and irreversible (GSK3B involved in COX2 regulation). These findings were tested against a second cohort of current former and non-smokers. “Those genes and functions which do not change by reversal to normal levels upon smoking cessation may give insight into why former smokers still maintain a assay of developing lung cancer,” according to Raj Chari first compose of the chew over. The study is the largest human SAGE study reported to date and also generated a large SAGE library for future investigate. Tobacco smoking accounts for 85 percent of lung cancers and former smokers account for half of those newly diagnosed with the disease.
