ASAH1 and invasive ductal breast carcinoma: The correlation between ASAH1 and clinical parameters was also more recently investigated in 120 specimens of non-special type invasive ductal carcinoma by Li Yu-hong’s group [72]; these authors found that high ASAH1 expression was correlated with lymph nodes metastasis, but there was no significant difference in ASAH1 expression levels between chemoresistant and chemosensitive groups.
