Researchers evaluated patients with advanced, nonsquamous, non-small cell lung cancer who had never received treatment and did not have an abnormal EGFR or ALK gene (KEYNOTE-189). In this study, 410 patients received 200 mg of Keytruda every 3 weeks plus chemotherapy (pemetrexed and a platinum...
one example of a gene mutation’s link to cancer is theEGFR, or epidermal growth factor receptor, gene. EGFR mutations are often connected with non-small cell lung cancer (NSCLC). These are mutations that only occur in tumor cells; they are not usually mutations that can run in a family....
Thus, while the past has been bleak, the future offers greater promise. Abstract Small-cell lung cancer (SCLC) is a deadly tumour accounting for approximately 15% of lung cancers and is pathologically, molecularly, biologically and clinically very different from other lung cancers. While the ...
The molecular location is more precise; however, small variations in the address may occur between research groups as a result of varying genome sequencing methods. For example, in humans, the chromosomal location of the EGFR gene is 7p12, while the molecular location is Chromosome 7, NC_...

Rhinovirus infections commonly evoke asthma exacerbations in children and adults. Recurrent asthma exacerbations are associated with injury-repair responses in the airways that collectively contribute to airway remodeling. The physiological consequences

Liver fibrosis develops from chronic liver inflammation. Macrophages, the key regulators of liver inflammation, dominate the progression and regression of liver fibrosis [24,25]. Follistatin-like protein 1 (FSTL1) is thought to be a proinflammatory gene involved in macrophage polarization that accelerat...
