              构体,生理情况下ANT主要参与膜两侧的腺嘌呤核苷二磷酸/腺嘌呤核苷三磷酸(adenosine diphosphate/adenosine triphosphate,
              ADP/ATP)交换,可能是构成线粒体渗透性转运孔(mitochondrial permeability transition pore,mPTP)的主要成分,并参与细胞凋

              disease occurrence

             [Abstract] Adenine nucleotide translocases(ANTs)are crucial for mitochondrial integrity and bioenergetic metabolism. There are
              four isoforms of ANTs. Under physiological conditions,ANTs primarily engage in the exchange of adenosine diphosphate(ADP)and
              adenosine triphosphate(ATP)across mitochondrial membranes. ANT isoforms are also potentially significant components of the
              mitochondrial permeability transition pore(mPTP),contributing to processes such as cellular apoptosis and proton leakage.
              Impairment of ANTs leads to mitochondrial dysfunction,which holds significant pathological implications in metabolic diseases,
              cardiomyopathies,and cancer progression. This review summarizes recent advancements and knowledge regarding ANTs,aiming to
              offer new insights into potential therapeutic strategies targeting ANTs in diseases.
