Mechanical Analysis of Phellinus Linteus‐Induced Apoptosis of Hepatoma Cells

ABSTRACT Liver cancer is prevalent with the third highest mortality rate globally. The biomechanical properties of cancer cells play a crucial role in their proliferation and differentiation. Studying the morphological and mechanical properties of individual living cells can be helpful for early diagnosis of cancers. Herein, atomic force microscopy (AFM) was used to investigate the effects of Phellinus linteus on hepatocyte cells (HL‐7702) and hepatocellular carcinoma cells (SMCC‐7721) in terms of morphological and mechanical changes at the nanoscale. The water extract of Phellinus linteus (PLWE) resulted in increased height and surface roughness of SMCC‐7721 cells. Also, the PLWE‐treated showed that the average adhesion decreased by 1.69 nN and the average Young's modulus increased by 0.379 kPa. Additionally, the SMCC‐7721 cells treated with PLWE showed clearly reduced activity compared with HL‐7702 cells. This study suggested that Phellinus Linteus could be a potential candidate for selective anti‐cancer therapy, providing a new avenue for the treatment of hepatocellular carcinoma.
