Synthesis of Aspirin | Sharmaine Bungabong - …
Regarding the possible anti-metastatic effect ofaspirin, it was demonstrated that the daily ingestion of aspirin inpatients previously treated with standard therapies indeed reducesmetastasis, assigning this effect to the maspin protein (). Maspin is a serine protease inhibitorof 42 kDa synthesized abundantly in normal mammary epithelialcells, and it has been shown that the expression of this protein isreduced in patients with breast cancer. Thus, the lack ofexpression of maspin in breast cancer has been suggested toindicate the presence of an aggressive and metastatic tumor(). Studies have revealed thatingestion of aspirin increases the levels of serum nitric oxide(NO) and maspin, both of which inhibited the growth of breastcancer cells , as well as invasion and metastaticprocesses in an animal model (,).This finding suggests that aspirin participates in the restorationof maspin synthesis at any stage of the disease, and also thatmaspin presents beneficial effects at any stage of tumoralprogression. It has been observed that maspin is reduced in BC, oreven absent in invasive cancer; hence, there is a correlationbetween the protein synthesis and its reduction according to cancertype and stage (). There is alsoevidence of maspin as an inhibitor of angiogenesis ().

The induction and overexpression of COX-2 and itsmain product PGE in human mammary tissue, have alsobeen associated with aromatase-catalyzed estrogen biosynthesis(). In addition, someepidemiologic studies have reported that hormone-receptor-positivebreast tumors are more responsive to aspirin (). The ability of aspirin and otherNSAIDs to protect against breast cancer might vary according tohormone receptor status. For instance, in 2004, a case-controlstudy, reported a reduction in risk only in women with hormonereceptor-positive tumors, but not in women with hormonereceptor-negative tumors ().Moreover, COX-2 is related to the activation of carcinogens,mutagenesis, angiogenesis, inhibition of apoptosis and metastasis(,,).In contrast, COX-2 inhibition may reverse these processes; aspirinand salicylates may also suppress NF-κB-related survival signalingby inhibiting IKKα activation, leading to apoptosis ().
