Adult rods are reprogrammed into cone-like cells in Nrltm1Jcco/Nrltm1Jcco Tg(CAG-cre/Esr1*)5Amc/0 mice

vision/eye
abnormal retina photoreceptor morphology ( J:193697 )
• tamoxifen-treated mice exhibit reprogramming of rods into cone-like cells
abnormal eye physiology ( J:193697 )
• in response to a series of light stimuli, reprogrammed retina in tamoxifen-treated mice exhibit lower maximal response amplitudes compared with control mice
• photopigment-bleached reprogrammed retina from tamoxifen-treated mice allowed to dark adapt in the presence of 9-cis-retinol are able to completely recover their photoresponse and largely restore their sensitivity
abnormal rod electrophysiology ( J:193697 )
• decreased scotopic a, but not b, wave amplitude in tamoxifen-treated mice
• like cone cells, dark-adapted reprogrammed rod cells in tamoxifen-treated mice exhibit a 35-fold desensitization and more rapid inactivation of photoresponse

nervous system
abnormal retina photoreceptor morphology ( J:193697 )
• tamoxifen-treated mice exhibit reprogramming of rods into cone-like cells
