Lens Proteomics: Exploring Adaptive Conflict in Uromastyx Hardwickii Lens Proteins
During last decade, proteomics has emerged as a powerful tool for high throughput screening, identification and quantification of proteins from biological samples. In current study, we have employed proteomics technique to explore proteins from eye lenses of Uromastyx hardwickii, an Indian spiny-tailed lizard. Water soluble and insoluble proteins from Uromastyx hardwickii lens were separated an...
متن کاملeye-lens protein y-crystallin
Although ubiquitous, no universal function can be confidently ascribed to glutathione. The eye lens maintains higher concentrations of reduced glutathione within its cells than do other tissues (Waley, 1969). The ratio of protein thiol to reduced glutathione in most species of lens is about 5:1 (Kuck et al., 1982). The requirement for glutathione in maintaining a transparent lens is indicated b...
متن کاملPrediction of Refractive Outcome of Second Eye with Partial Adjustment of Intraocular Lens Power of the First Eye
Background and Objective: This study aimed at comparing the results of refractive cataract surgery in patients undergoing sequential surgeries in both eyes. Considering the preoperative refraction and final refraction of the first eye, it is possible to correct the refrative result of cataract surgery using the adjustment of the second eye intraocular lens (IOL) power. Materials and Methods: T...
متن کاملDisulfide bond formation in the eye lens.
The disposition and disposal of the -SH groups of the lens during aging and cataractogenesis have been investigated by laser Raman spectroscopy as a noninvasive microprobe in the intact living lens. In this procedure -SH and -S-S- give unique discrete Raman signals (at 2580 and 508 cm-1) that may be used to calculate relative concentrations in a very small volume of the lens. We present evidenc...
متن کاملMolecular interactions in the eye lens.
Introduction The lens is a cellular structure formed from elongated fibre cells aligning into concentric layers that stack together with the organization of a uni-axial crystal 111. Within the fibre cells, where protein turnover is low, protein components are packed together [2-41 with short-range order [S]. The high protein concentration is important both for refraction and transparency. Globu...
