  • Associations of Omega-3 Fatty acids with Interstitial Lung Disease and Lung Imaging Abnormalities Among Adults - Am J Epidemiol 2020 Aug 17 - "Docosahexaenoic acid (DHA), an omega-3 polyunsaturated fatty acid, attenuates interstitial lung disease (ILD) in experimental models but human studies are lacking. We examined associations of circulating levels of DHA, and other polyunsaturated fatty acids, with hospitalization and death due to ILD over 12 years in the Multi-Ethnic Study of Atherosclerosis (MESA, n=6,573). We examined cross-sectional associations with CT lung abnormalities in MESA (2000-2012), Framingham Heart Study (2005-2011), and Age Gene/Environment Susceptibility (2002-2006) Study (total n=10,193). Polyunsaturated fatty acid levels were from fasting blood samples and extracted from plasma phospholipids (MESA and Age Gene/Environment Susceptibility) or red blood cell membranes (Framingham Heart Study). Higher DHA levels were associated with a lower risk of hospitalizations due to ILD (adjusted rate ratio 0.69 per standard deviation increment (95% CI 0.48, 0.99) and a lower rate of death due to ILD (adjusted hazard ratio 0.68 per standard deviation increment, 95% CI 0.47, 0.98). Higher DHA was associated with less interstitial lung abnormalities on CT (pooled adjusted odds ratio 0.65 per natural log increment; 95% CI 0.46, 0.91). Higher DHA levels were associated with a lower risk of hospitalization and death due to ILD and less lung abnormalities on CT in a meta-analysis of population-based cohorts." - [Nutra USA] - See docosahexaenoic acid at Amazon.com.
  • Fluvastatin inhibits HMG-CoA reductase and prevents non-small cell lung carcinogenesis - Cancer Prev Res (Phila). 2019 Sep 25 - "Lung cancer is the leading cause of cancer death worldwide ... our findings suggest that fluvastatin might be promising chemopreventive or potential therapeutic drug against NSCLC tumorigenesis, providing hope for rapid clinical translation"
  • Magnesium intake and lung cancer risk: A systematic review and meta-analysis - Int J Vitam Nutr Res. 2019 Jul 15:1-8 - "The pooled relative risk (RR) indicated a significant association between lung cancer incidence and magnesium intake (RR = 0.88, 95% CI = 0.79 to 0.98; p = 0.018). To investigate the cause of heterogeneity of these studies (I2 = 75.8%, p < 0.001), we performed a subgroup analysis which was affected by the mean dose of magnesium intake, where doses of magnesium intake lower than 300 mg/d significantly decreased lung cancer risk (RR = 0.83, 95% CI = 0.70 to 0.99; p = 0.034). Increasing magnesium intake doses to over 300 mg/d did not reduce the incidence of lung cancer (RR = 0.89, 95% CI = 0.78 to 1.01; p = 0.076). Our meta-analysis suggests that magnesium intake of less than 300 mg/d may have protective effects in lung cancer." - See magnesium supplements at Amazon.com.
  • A grape constituent protects against cancer - Science Daily, 10/3/18 - "This 26 week long study contained four groups of mice. The first one, the control, received neither carcinogen nor resveratrol treatment. The second received only the carcinogen, the third received both the carcinogen and the treatment, and the fourth received only the treatment. "We observed a 45% decrease in tumor load per mouse in the treated mice. They developed fewer tumors and of smaller size than untreated mice," says Muriel Cuendet. When comparing the two groups that were not exposed to carcinogen, 63% of the mice treated did not develop cancer, compared to only 12.5% of the untreated mice. "Resveratrol could therefore play a preventive role against lung cancer," she continues" - See resveratrol products at Amazon.com.
  • Metformin Has Positive Therapeutic Effects in Colon Cancer and Lung Cancer - Am J Med Sci. 2017 Sep;354(3):246-251 - "Metformin (MF), a diabetic drug, has antineoplastic activity as adjuvant therapy for breast cancer and prostate cancer. MF is thought to work via inhibition of mammalian target of rapamycin and activation of p53 and liver kinase B1 via adenosine 5'-monophosphate-activated protein kinase ... For CC, the MF group noted fewer deaths (48% versus 76%, P < 0.001), recurrences (4% versus 19%, P = 0.002), metastases (23% versus 46%, P = 0.001), better 5-year survival rates (57% versus 37%, P = 0.004), overall survival years (5.7 versus 4.1, P = 0.007) and greater carcinoembryonic antigen decrease (72% versus 47%, P = 0.015). MF was associated with improved 5-year survival rates (29% versus 15%, P = 0.023) and overall survival years (3.4 versus 1.8, P < 0.001) in LC" - See metformin at The Antiaging Store.
  • Resveratrol may be an effective intervention for lung aging - Science Daily, 2/22/17 - "Resveratrol (RSL) ... In healthy young adults, breathing is an essential, efficient process, but natural aging of the lung occurs at a steady and irreversible rate, as measured by a decline in lung function. This natural deterioration leads to a significantly reduced quality of life, over a time frame dependent on genetic and environmental factors. Although some available therapies can ameliorate symptoms, aging-related lung failure is generally irreversible and is accompanied by high rates of morbidity and mortality due to increased disease risk, including development of COPD, with accompanying emphysema and chronic bronchitis ... The research team found that inhaled, prophylactic resveratrol treatments can slow the rate of lung function decline, alveolar enlargement and alveolar epithelial type 2 cell DNA damage that occurs in the early stages of lung aging. They concluded that administration of resveratrol directly to the lungs may be an effective intervention for lung aging, which is a significant risk factor for development of chronic lung disease" - I would think that by taking it orally it would make its way into the cells of the lungs although at a lower concentration.  See Reserveage Nutrition - Resveratrol with Pterostilbene 500mg, Cellular Age-Defying Formula, 60 veg capsules at Amazon.com.
  • Beta-cryptoxanthin, a carotenoid, inhibits nicotine-linked lung cancer development in mice - Science Daily, 11/1/16 - "The team calculated that these doses are equivalent to approximately 0.087 and 0.87 milligrams of daily BCX intake in humans (eating a tangerine or cup of sweet red peppers per day, for example) ... At the end of the experimental period, mice fed BCX developed on average 50 to 60 percent fewer tumors than mice not fed BCX ... The team's findings corroborate human epidemiological studies that have found an association between higher BCX intake and lower risk of lung cancer in current smokers from North America and Asian countries"

  • Soy increases radiation's ability to kill lung cancer cells, study shows - Science Daily, 4/1/11 - "These natural soy isoflavones can sensitize cancer cells to the effects of radiotherapy, by inhibiting survival mechanisms which cancer cells activate to protect themselves ... At the same time, soy isoflavones can also act as antioxidants in normal tissues, which protect them against unintended damage from the radiotherapy ... soy isoflavones increase killing of cancer cells by radiation via blocking DNA repair mechanisms, which are turned on by the cancer cells to survive the damage caused by radiation ... Researchers used a formulation consisting of the three main isoflavones found in soybeans, including genistein, daidzein and glycitein ... Previously, researchers had found that pure genistein demonstrated antitumor activity in human NSCLC cell lines and enhanced the effects of EGFR-tyrosine kinase inhibitors. This study showed that the soy mixture had an even greater antitumor effect than pure genistein" - See soy isoflavones at Amazon.com.
  • Vitamin D linked to lung cancer survival, study suggests - Science Daily, 3/1/11 - "Recent research suggests vitamin D may be able to stop or prevent cancer. Now, a new study finds an enzyme that plays a role in metabolizing vitamin D can predict lung cancer survival ... Levels of the enzyme, called CYP24A1, were elevated as much as 50 times in lung adenocarcinoma compared with normal lung tissue. The higher the level of CYP24A1, the more likely tumors were to be aggressive. About a third of lung cancer patients had high levels of the enzyme. After five years, those patients had nearly half the survival rate as patients with low levels of the enzyme ... Researchers then linked this to how CYP24A1 interacts with calcitriol, the active form of vitamin D" - See vitamin D at Amazon.com.

  • Curcumin promotes apoptosis in A549/DDP multidrug-resistant human lung adenocarcinoma cells through an miRNA signaling pathway - Biochem Biophys Res Commun. 2010 Jul 10 - "Curcumin extracted from the rhizomes of C. longa L has been shown to have inhibitory effects on cancers through its anti-proliferative and pro-apoptotic activities. Emerging evidence demonstrates that curcumin can overcome drug resistance to classical chemotherapies. Thus, the mechanisms underlying the antitumor activities of curcumin require further study. In our study, we first demonstrated that curcumin had anti-cancer effects on A549/DDP multidrug-resistant human lung adenocarcinoma cells. Further studies showed that curcumin altered miRNA expression; in particular, significantly downregulated the expression of miR-186 * in A549/DDP. In addition, transfection of cells with a miR-186 * inhibitor promoted A549/DDP apoptosis, and overexpression of miR-186 * significantly inhibited curcumin-induced apoptosis in A549/DDP cells. These observations suggest that miR-186 * may serve as a potential gene therapy target for refractory lung cancer that is sensitive to curcumin" - See curcumin products at Amazon.com.
