The expression of retinoblastoma and several retinoblastoma-related genes was studied in glioma cell line U87 and its subline with knockdown of ERN1 (endoplasmic reticulum—nuclei-1), the main endoplasmic reticulum stress sensing and signaling enzyme. It was shown that a blockade of the ERN1 enzyme function increases the expression levels of retinoblastoma, retinoblastoma-like 1 and most retinob...

We have previously shown pp32 and the retinoblastoma protein interact. pp32 and the retinoblastoma protein are nuclear receptor transcriptional coregulators: the retinoblastoma protein is a coactivator for androgen receptor, the major regulator of prostate cancer growth, while pp32, which is highly expressed in prostate cancer, is a corepressor of the estrogen receptor. We now show pp32 increas...

PURPOSE Recent reports suggest the association of human papilloma virus (HPV) with retinoblastoma. This study was performed to elucidate whether HPV infection is related to retinoblastoma among Koreans. METHODS A total of 54 cases diagnosed with retinoblastoma were enrolled from Seoul National University Children's Hospital and Seoul Metropolitan Government-Seoul National University Boramae M...

Retinoblastoma is an embryonic intraocular tumor arising in the retina of eye. It a dangerous that can damage eye and its surrounding components. Chromosome 13q14.1-14.2 cytogenetic location RB1 gene. As result, early identification children essential. Over last few decades, treatment has improved with goal not only saving life but also optimizing residual vision. In oncology, machine learning ...

GLycolytic enzymes were studied from normal human retinas (both fetal and adult) and from retinoblastomas of eight patients and an established retinoblastoma cell line. No significant differences were found between the enzyme activities in the tissues investigated except for hexokinase and pyruvate kinase, which were significantly decreased in the tumor cells. In fetal retina, five different fo...

Retinoblastoma is the most common intraocular cancer in children, affecting 1/20,000 live births. Currently, children with retinoblastoma were treated with chemotherapy using drugs such as carboplatin, vincristine, and etoposide. Unfortunately, if conventional treatment fails, the affected eyes should be removed to prevent extension into adjacent tissues and metastasis. This study is to investi...

Superselective ophthalmic artery injection of the chemotherapeutic agent is a new treatment option for advanced retinoblastoma.[1] We present case severe bronchospasm with loss tidal volume and oxygen desaturation in an infant during catheterization under general anesthesia.

PURPOSE Retinoblastoma, a childhood cancer of the retina, is caused by inactivation of the tumor suppressor gene retinoblastoma (RB). Cotylenin A (CN-A), a novel fusicoccane-diterpene glycoside, accelerates the differentiation of several types of myeloid cell lines and is a candidate for a new type of anticancer therapeutic agent with this effect. However, whether CN-A has the same effect on re...

Aberrant expression of miR-204 had been frequently reported in cancer studies; however, the mechanism of its function in retinoblastoma remained unknown. Here, we reported that miR-204 was frequently downregulated in retinoblastoma tissues and cell lines. Enforced expression of miR-204 inhibited retinoblastoma cells' proliferation and invasion. In vivo study indicated that restoration of miR-20...

Retinoblastoma is the most common intraocular tumor in childhood. In majority of early stage retinoblastoma, the eyeballs as well as vision can be preserved with chemotherapy and local intraocular therapy with laser or photocoagulation. However, more than half the patients in India and other developing nations present in advanced stage of the disease. This article reviews the genetics, clinical...
