Lung cancer represents one of the most prevalent
neoplasms across the globe. Tobacco smoking, exposure to different occupational and
environmental carcinogens, and various dietary factors are strongly implicated in the development of
lung cancer. The 5-year survival rate of
lung cancer is extremely poor which can be attributed to its propensity for early spread, lack of appropriate
biomarkers and proper therapeutic strategies for this aggressive
neoplasm. Emerging evidence suggests
tumor necrosis factor-α-induced
protein eight like 1 (TIPE1 or TNFAIP8L1), which functions as a cell death regulator, to hold high prospect as an important
biomarker. Interestingly, this
protein was found to be significantly downregulated in human
lung cancer tissues compared to normal lung tissues. In addition, this
protein exerted marked downregulation in different stages and grades of lung
tumor. Further knockout of TIPE1 led to the enhancement in proliferation, survival, migration and invasion of NCIH460 human
lung cancer cells through modulation of Akt/mTOR/STAT-3 signaling cascade. In addition, TIPE1 was found to be involved in
nicotine,
4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone,
N-nitrosonornicotine and
benzo[a]pyrene-mediated
lung cancer through enhanced proliferation, survival and migration of
lung cancer cells. Altogether, this newly identified
protein plays a critical role in
lung cancer pathogenesis and possess enormous prospect to serve as an important tool in the effective management of this aggressive
neoplasm.
