Lung cancer is a medical condition caused abnormal growth of the cells in the lung’s tissue. Most common form of primary lung cancers is derived from epithelial cells.
Most common types of lung cancers include
* Squamous-cell carcinoma often found in an outer area of the lung
* Large-cell carcinoma found in the center of the lung by an air tube
* Adenocarcinoma found in any part of the lung.
According to the statistics provided by the American cancer society, lung cancer is a leading cause of death among both men and women. Most people diagnosed with lung cancer are 65 or older, compared to a very small number of people diagnosed are younger than 45.
Smoking is a major cause of lung cancer by enhancing oxidation stress by combining the inhaling air with cancer-causing chemical substances (carcinogens) in the cigarette.
Normally, our body can withstand and repair this damage, but prolonged exposure your lung to these danger carcinogens can result in lung cancer development.
2. Second-hand smoke
Prolonged exposure to second-hand smoke can also increase the risk of lung cancer.
3. Exposure to certain chemicals
There is an increased risk of lung cancer for people who inhale or exposing certain industrial chemical such as radon gas, arsenic, chromium, nickel, etc. in the workplace.
4. Family history
Risk of lung cancer increased if one of the members of your direct family has lung cancer.
5. Lung disease
Risk of ling can caner increase if you have or previously had certain types of lung disease
6. Excessive drinking
According to the study by Freudenheim et al., R. Curtis Ellison MD suggested that alcohol intake of more than 2 drinks per day is associated with a small increased risk of lung cancer. This study, like others, suggests a weak, positive association between consuming larger amounts of alcohol (>2 drinks a day) and lung cancer risk.
Dr. Federico Venuta, the lead researcher wrote, “The respiratory system undergoes a number of structural, physiological and immunological changes with age. For this reason, at this stage of our life, it is not always easy to differentiate disease from a normal state”.
With an aim to find a natural and potential compound for the treatment of non-small lung cancer (NSCLC) with no side effects, researchers investigated Cucurbitacin B (CuB), a natural compound isolated from cucumber and other vegetables anti-NSCLC in vitro.
Four NSCLC cells (H1299, A549, HCC-827, and H661) in vitro and the highly aggressive H1299 xenograft in vivo were included in the study.
According to the tested assays, CuB significantly induced G2/M cell-cycle arrest and mitochondrial apoptosis.
Injection by the thiol antioxidant N-acetylcysteine (NAC) in the experiment showed to attenuate all cellular effects of CuB completely.
Further analysis of the anti-NSCLC efficacy of CuB, researchers found that CuB induces cell death via rapidly and significantly decrease the levels of protein thiols and GSH/GSSG ratio by disrupting cellular redox balance induced cytotoxicity.
Dr. Kausar H, the lead scientist said, “CuB interacts with and modulates cellular thiols to mediate its anti-cancer effects. Collectively, our data shed new light on the working mechanisms of CuB and demonstrate its therapeutic potential against NSCLC”.
Moreover, in experimental EMT model CuB also suppressed the overexpression of protein associated with the production of proinflammatory cytokines in the initiation of cellular change and Wnt/β-catenin signaling axis in stimulating the production of formation of new blood vessels to facilitate cancer proliferation.
