Although two meta-analyses did not find an overall association between folate intake and breast cancer risk (Lewis et al, 2006; Larsson et al, 2007), in some studies, folate intake was inversely associated with breast cancer risk in the whole population (Ericson et al, 2007), or among alcohol drinkers (Zhang et al, 1999; Rohan et al, 2000), or with certain hormone receptor types of breast cancer (Zhang et al, 2005; Larsson et al, 2008; Maruti et al, 2008). Here, NR4A1 is linked to breast cancer.
