Retinoblastoma (Rb) is a rare form of cancer that rapidly develops from the immature cells of a retina, [2] the light-detecting tissue of the eye. [3] It is the most common primary malignant intraocular cancer in children, especially those under 3 years old.
Located in Philadelphia, the Wills Eye Hospital sees at least 50% of the 300 children diagnosed with retinoblastoma each year and at least 1/3 of the adults diagnosed with ocular melanoma in the USA. She was voted by her peers to be in the 2014 and 2016 Ophthalmology Top 100 Power List, which comprises a list of the top 100 most influential ...
The retinoblastoma protein (protein name abbreviated Rb or pRb; gene name abbreviated Rb, RB or RB1) is a tumor suppressor protein that is dysfunctional in several major cancers. [5] One function of pRb is to prevent excessive cell growth by inhibiting cell cycle progression until a cell is ready to divide.

Retinoblastoma - Strabismus (crossed eyes), a whitish or yellowish glow through the pupil, decreasing/loss of vision, sometimes the eye may be red and painful. Retinoblastoma can occur in one or both eyes. This tumor occurs in babies and young children. It is called RB for short.
The classical example of such a loss of protecting genes is hereditary retinoblastoma, in which one parent's contribution of the tumor suppressor Rb1 is flawed. Although most cells will have a functional second copy, chance loss of heterozygosity events in individual cells almost invariably lead to the development of this retinal cancer in the ...
Retinoblastoma protein (pRb). pRb was the first tumor-suppressor protein discovered in human retinoblastoma ; however, recent evidence has also implicated pRb as a tumor-survival factor. RB1 gene is a gatekeeper gene that blocks cell proliferation, regulates cell division and cell death. [ 8 ]
