Background: Familial Meniere's disease (FMD) is a rare polygenic disorder of the inner ear. Mutations in the connexin gene family, which encodes gap junction proteins, can also cause hearing loss, but their role in FMD is largely unknown.
Methods: We retrieved exome sequencing data from 94 individuals in 70 Meniere's disease (MD) families.

Sensorineural hearing loss (SNHL) is an increasingly prevalent sensory disorder, but the underlying mechanisms remain poorly understood. Adaptor related protein complex 2 subunit beta 1 (AP2B1) has been indicated to be detectable in mature cochleae. Nonetheless, it is unclear whether AP2B1 is implicated in the progression of SNHL.

Introduction: Dentists and dental professionals report a high prevalence of noise-induced hearing loss (NIHL) and related symptoms. Chronic exposure to high-frequency dental instrument sounds, which can damage the outer hair cells (OHCs) of the cochlea, is strongly linked to their NIHL. Similarly, dental students in teaching clinics often report symptoms associated with NIHL.

Dihydrotestosterone (DHT), an androgen derivate, is known to be a key factor involved in androgenetic alopecia. DHT suppresses the growth of outer root sheath cells and induces apoptosis of hair keratinocytes, thereby causing hair follicle miniaturization and hair regrowth inhibition. Forsythoside A, a natural substance derived from Forsythia suspensa, has been shown to reduce DHT-induced apoptosis in human hair cells and suppress hair regrowth inhibition induced by DHT in mice.

Liaoning cashmere goat is an outstanding breed in China primarily for cashmere production, with strict controls against genetic outflow. Melatonin(MT) is a key factor affecting cashmere growth, and preliminary transcriptome sequencing indicated that melatonin upregulates the expression of the PIP5K1A gene in skin fibroblasts. To predict the physicochemical properties of PIP5K1A in Liaoning cashmere goats, ascertain the tissue localization of PIP5K1A in their skin, and explore the role and mechanism of PIP5K1A in the proliferation of skin fibroblasts.
