Aminoglycoside-Induced Hair Cell Death and Potential Therapies

Words: 1590 Pages: 5 5628

Introduction Hearing loss is the third most common disorder in the United States, being more prevalent than diabetes or cancer (Blackwell et al., 2014). Our ability to hear is dependent on hair cells that can translate the sounds we hear into electrical impulses that can be interpreted by the brain. When sound waves enter the cochlea located in the inner ear, they deflect the apical portion of hair cells, also known as stereocilia. Stereocilia are connected to one another via […]

Cyclic GMP-AMP Synthase

Words: 385 Pages: 1 5509

Genomic DNA can be damaged by endogenous or environmental stresses. During repair, these short single-stranded DNAs are continuously generated and may leak out to the cytoplasm, where they are generally drawn back into the nucleus by DNA repair and replication factors (RPA and Rad51). Alongside this, TREX1, a cytoplasmic exonuclease, is anchored on the outer nuclear membrane to degrade leaking DNAs immediately. This prevents activation of the cGAS/STING pathway against self DNA. Inhibition of any of the above-mentioned proteins leads […]

The Role of Senescent Cells in Ageing and Cancer Suppression

Words: 1175 Pages: 4 6787

Senescent cells, often termed as "zombie cells," are somatic cells that, although no longer capable of dividing, display resistance to apoptosis, the process of programmed cell death (Scudellari, 2017). These cells accumulate in various body parts, exhibiting unique resistance to apoptosis, expressing distinct extracellular proteins, and secreting diverse molecules, including cytokines (Scudellari, 2017). This secretory activity is known as the cell's senescence-associated secretory phenotype (SASP). The presence of zombie cells and their SASPs can lead to various outcomes (Coppé, Desprez, […]
