“…Transcription of proinflammatory mediators, such as cytokines and chemokines (i.e., IL-8), can be regulated by nuclear factor-кB (NF-кB) [17,18]. Activation of NF-кB in immune cells up-regulates the expression of cytokines and growth factors that are essential to the immune response and that contribute to inflammation [19].…”

“…TIMP-1 has been shown to have anti-apoptotic and proliferative properties [18,19], and the absence of TIMP-1 has been associated with increased chemotherapy sensitivity [20,21]. Fu et al showed that overexpression of TIMP-1 significantly decreased the sensitivity of MDA-435 breast cancer cells to epirubicin and paclitaxel [22]. Further, Schrohl et al selected a group of 525 premenopausal patients who had received either CMF, anthracycline-based or no adjuvant chemotherapy.…”

“…We mapped the most upregulated proteins and phospho-proteins to functional classes using IPA and found enrichment for processes that TIMP-1 is believed to be involved in, for example, apoptosis, cell cycle, transcription factors, DNA repair, drug transport, and drug resistance/sensitivity. [7][8][9][10][11]28,59 It is particularly interesting that all the identified topoisomerases were either hyper-phosphorylated or overexpressed since this may explain why previous studies found high TIMP-1 levels in tumor or plasma to be associated with decreased benefit from topoisomerase inhibitor containing chemotherapy, 12−15 as both topoisomerase 1 and 2 activity is positively dependent on phosphorylation. 60−62 It is therefore intriguing to speculate that increased expression levels and phosphorylation status of topoisomerases may cause the chemotherapy resistance phenotype.…”
