Establishing chronic models of age-related macular degeneration via long-term iron ion overload
Am J Physiol Cell Physiol. 2024 Feb 26. doi: 10.1152/ajpcell.00532.2023. Online ahead of print.ABSTRACTAge-related macular degeneration (AMD) is characterized by the degenerative senescence in the retinal pigment epithelium (RPE) and photoreceptors, which is accompanied by the accumulation of iron ions in the aging retina. However, current models of acute oxidative stress are still insufficient to simulate the gradual progression of AMD. To address this, we established chronic injury models by exposing the aRPE-19 cells, 661W cells, and mouse retina to iron ion overload over time. Investigations at the levels of cell biolo...

Cannabidiol protects C2C12 myotubes against cisplatin-induced atrophy by regulating oxidative stress
Am J Physiol Cell Physiol. 2024 Feb 26. doi: 10.1152/ajpcell.00622.2023. Online ahead of print.ABSTRACTCancer and chemotherapy can both cause cachexia, a complex multi-organ syndrome characterized by body weight loss, due to adipose tissue and skeletal muscle wasting. Changes in body weight and muscle mass are predictive of response to chemotherapy, incidence of treatment-related complications and, ultimately, patient survival, but there are currently still no clear therapeutic strategies to counteract cachexia. Cannabidiol (CBD) is a bioactive phytocannabinoid produced from a plant named Cannabis sativa. In recent years, ...

Implications of IFN γ SNP rs2069705 in Primary Sjögren's Syndrome: Transcriptional Activation and B Cell Infiltration
CONCLUSION: SNP rs2069705 in the IFNγ gene emerges as a pivotal element in pSS susceptibility, primarily by augmenting IFNγ transcription, activating the JAK/STAT1 pathway, and leading to B lymphocyte infiltration in the exocrine glands.PMID:38406824 | DOI:10.1152/ajpcell.00661.2023 (Source: Am J Physiol Cell Ph...)

Normal vision and development in mice with low functional expression of Kir7.1 in heterozygosis for a blindness-producing mutation inactivating the channel
Am J Physiol Cell Physiol. 2024 Feb 26. doi: 10.1152/ajpcell.00597.2023. Online ahead of print.ABSTRACTK+ channel Kir7.1 expressed at the apical membrane of the retinal pigment epithelium (RPE) plays an essential role in retinal function. An isoleucine-to-threonine mutation at position 120 of the protein is responsible for blindness-causing vitreo-retinal dystrophy. We have studied the molecular mechanism of action of Kir7.1-I120T in vitro by heterologous expression and in vivo by in CRISPR-generated knockin mice. Full-size Kir7.1-I120T reaches the plasma membrane but lacks any activity. Analysis of Kir7.1 and the I120T mu...
