Diffuse Anterior Retinoblastoma with Sarcoidosis-Like Nodule
BACKGROUND Retinoblastomas account for 4% of malignancies in children, 1-2% of which are diffuse infiltrating retinoblastomas. Diffuse anterior retinoblastoma is rare and does not involve the retina. Here, we report on a diffuse anterior retinoblastoma with large sarcoidosis-like nodules on the iris that were responsive to anti-inflammatory therapy. CASE We present a 6-year-old girl who had a...

متن کاملNucleocytoplasmic shuttling of p130/RBL2: novel regulatory mechanism.
The retinoblastoma-related pocket proteins pRb, p107, and p130 are implicated in the control of cell proliferation, differentiation, and transformation. The function of pocket proteins is in part mediated by their ability to inhibit specific E2F transcription factors. The transcriptional activity of E2Fs is controlled by alteration of their nucleocytoplasmic localization during the cell cycle. ...
متن کاملPromoter Methylation Status Modulate the Expression of Tumor Suppressor (RbL2/p130) Gene in Breast Cancer
BACKGROUND Aberrant expression of tumor suppressor genes may correspond to the abnormal cell development and tumorigenesis. Rbl2/p130, a member of retinoblastoma family of proteins, has growth suppressive properties. Numerous studies reported de-regulation of Rbl2/p130 in various types of cancer as a consequence of a number of genetic alterations. However, role of epigenetic mechanisms like DNA...
