Photoisomerization of 11-cis-retinal to all-trans-retinal triggers phototransduction in the retinal photoreceptor cells and causes ultimately the sensation of vision. 11-cis-Retinal is enzymatically regenerated through a complex set of reactions in adjacent retinal pigment epithelial cells (RPE). In this study using

Optical control of the primary step of photoisomerization of the retinal molecule in bacteriorhodopsin from the all-trans to the 13-cis state was demonstrated under weak field conditions (where only 1 of 300 retinal molecules absorbs a photon during the excitation

The objective of this prospective, monocentric phase-II pilot study was to evaluate toxicity and efficacy of neoadjuvant temozolomide (TMZ) and 13-cis retinoic acid (13-cRA) treatment in patients with newly diagnosed anaplastic gliomas after total or subtotal tumor resection. The primary

Biochemistry, 39(37), 11370-11380 (2000-09-14)
In the retinal rod and cone photoreceptors, light photoactivates rhodopsin or cone visual pigments by converting 11-cis-retinal to all-trans-retinal, the process that ultimately results in phototransduction and visual sensation. The production of 11-cis-retinal in adjacent retinal pigment epithelial (RPE) cells

Topoisomerase I inhibitors, such as CPT-11, are potent anticancer drugs against neuroblastoma (NB). Differentiating agents, such as retinoids, improve the survival of children with metastatic NB. To characterize the biological effects associated with exposure to CPT-11 in vivo, athymic mice
