Intriguingly, low expression of ARHGAP10 was more frequent in patients with cTNM stage II than in those with stage I. In addition, ARHGAP10 expression was lower in invasive ductal breast carcinoma than in adjacent normal tissues, whereas ARHGAP10 expression did not differ between ductal breast cancer in situ and normal tissues, as determined using the Radvanyi Breast dataset in Oncomine (Radvanyi et al., 2005). Here, ARHGAP10 is linked to invasive ductal breast carcinoma.
