TUBA4A and breast angiosarcoma: This study evaluated the presence and clinical–laboratory outcomes attributable to alterations in the primary cilia and cytoplasmic tubulin expression in the intrahepatic biliary epithelium, observing that reduced PC length, decreased PC bending, and increased intensity of cytoplasmic TUBA4A occur in the isolated BA type, and negatively impact the postoperative prognosis after portoenterostomy (Figure 7).
