CALU and neoplasm: In accord with the findings of these murine and human studies13,25, we found a significant fold increase in the levels of specific tumor suppressor/anticancer proteins at the end of 4th week during 4-week intermittent fasting from dawn to sunset and/or 1 week after 4-week intermittent fasting from dawn to sunset, including CALR, CALU, INTS6, KIT, CROCC, PIGR, IGFBP4, and SEMA4B that are downregulated in several cancers resulting in cancer metastasis and poor prognosis (Table 2, Fig. 2).
