Based on estimates, the incidence of lung cancer will linearly improve over the next 20 years [2,3]. For that reason, prevention and remedy of lung cancer is significant. At present, surgery, chemotherapy, and radiotherapy will be the major remedy choices for lung cancer; even so, all of these choices have disadvantages: surgery is risky and restrictive [4,5], chemotherapy is not entirely successful and may bring about drug resistance [6], and radiotherapy is linked with really serious unwanted effects [7]. The five-year survival rates of individuals with stage IA, IB, IIA, IIB, IIIA, IIIB, and IV lung cancers are 73 , 58 , 46 , 36 , 24 , 9 , and 2 , respectively [8]. Thus, identifying novel biomarkers for early diagnosis and targeted therapy is significant for the prevention and treatment of lung cancer [9]. TMEM16A is actually a calcium-activated chloride channel (CaCC) with important physiological functions [10,11]. TMEM16A is extensively expressed in epithelial and smooth muscle tissues at the same time as in a variety of glands with the human body [12]. Studies have shown that TMEM16A (also known as ANO1, DOG1, TAOS2, or ORAOV2) is connected with many cancer varieties [13,14]. The TMEM16A protein is very expressed in oral, esophageal, lung, liver, and prostate cancers; its overexpression is closely associated towards the proliferation and migration of cancer cells [15,16]. Additionally, clinical data indicate that TMEM16A can also be considerably associated with poor prognosis in some cancers [17]. Numerous current research have shown that inhibiting the overexpression of TMEM16A in lung cancer impedes tumorInt. J. Mol. Sci. 2021, 22, 10930. 10.3390/ijmsmdpi/journal/ijmsInt. J. Mol. Sci. 2021, 22,two ofevolution [18]. As a result, TMEM16A has Fexofenadine-d10 web emerged as a potential drug target for lung cancer remedy [19]. Homoharringtonine (HHT) is definitely an alkaloid isolated from plants (conifers) in the Cephalotaxaceae household [20]. It can be clinically employed to treat chronic myelogenous leukemia (CML), acute myeloid leukemia (AML), and malignant lymphoma [21,22]. On the other hand, the molecular mechanisms underlying the anti-cancer effects of HHT are usually not clear. Research have shown that HHT inhibits cancer cell proliferation by inhibiting protein and DNA syntheses [23]. The lethality of HHT against G1 and G2 phase cells is robust, but the effect on S phase cells is weak. In CML, HHT prevents the elongation step of protein synthesis by interacting with all the A-site of the ribosome and disrupting the positioning of Spisulosine References aminoacyl-tRNAs [24]. In breast cancer, HHT suppresses cell growth and promotes apoptosis by regulating the miR-18a-3p-AKT-mTOR signaling pathway [25]. In FLT3-ITD AML, HHT induces cancer cell apoptosis by means of inhibiting the FLT3-AKT-c-Myc pathway [26]. Even though there happen to be a number of studies on HHT anti-cancer properties, the HHT receptors on lung cancer cells plus the downstream signal transduction mechanisms associated to HHT.
