LHFPL5 gene is involved in the electromechanical conduction of cochlear hair cells and plays an important role in maintaining hearing and balance functions.This review aims to investigate the mechanism of LHF-PL5 gene and its related proteins in the pathogenesis of hearing loss.We analyzed the hearing loss caused by LHF-PL5 gene mutation,and discussed the characteristics of hearing loss population.The molecular etiology of deafness caused by LHFPL5 gene was discussed through the conclusion and summary of the study results,which provided a basis for whether LHFPL5 gene screening was necessary for deaf people in China,and provided theoretical guidance for subsequent basic research and clinical diagnosis and treatment.

Cell-penetrating peptides (CPPs) offer a non-selective and receptor-independent mode to promote cellular uptake. Although the non-specificity of CPP-mediated internalization allows this approach applicable to a wide range of tumor types potentially, their universality is a significant obstacle to their clinical utility for targeted delivery of cancer therapeutics and imaging agents. Accordingly, many reports have focused on selective switching of systemically delivered inert CPPs into their active form in lesions (tumor). In this review, our attention is mainly confined to such an enzyme-sensitive domain incorporated delivery system with activatable CPPs (ACPPs), which have displayed the exciting strength in balancing the CPPs' pros and cons, and potential in the treatment and diagnosis of some diseases.
