Glucosamine ring, glucosamine linear, glucuronic acid linear, rhamnose linear, glucuronic acid ring, galactose ring, mannose, glucose, and xylose showed a strong binding potential against HDAC1, HDAC2, HDAC4, HDAC5, HDAC6, HDAC7, HDAC8, and HAT, indicating these polysaccharides as potential breast cancer inhibitors [83]. The gene discussed is HDAC2; the disease is breast cancer.
