TCHP and cancer: Therefore, future studies should examine whether (morphologically) normal cells from cancer patients, in particular those adjacent to primary tumors and their metastases, i.e. pertaining to their (inflammatory) microenvironment [16], contain oncoprotein-tumor suppressor protein heterodimers (Fig. 1b) or, respectively, their correlates, e.g. posttranslational tumor suppressor protein modifications such as RB (hyper)phosphorylations [17].
