A study found that prolonged sun exposure, especially in teens and 30s, increases the risk of age-related maculopathy. Wearing hats and sunglasses also reduces this risk by half.
The study reveals Rb protein is crucial for retinal cell proliferation and rod development, providing clues to improving treatment of retinoblastoma. Understanding Rb's role in normal mouse development can help explain why mice without the gene don't develop the disease.
A 57-year study found that hereditary retinoblastoma patients have a significantly higher risk of developing a second primary cancer, with an increased incidence of melanomas and sarcomas. The risk is independent of radiotherapy treatment.
Researchers find that spontaneous neuronal activity in the retina is crucial for the formation of separate left and right eye connections to the brain. Blocking all activity in the retina leads to abnormal development of these connections.
Researchers at St. Jude Children's Research Hospital have identified a critical role for the gene Prox1 in regulating the development of the retina, ensuring proper formation and organization of complex tissue. The study found that Prox1 directs progenitor cells to stop multiplying, resulting in a precise ratio of horizontal cells to r...
Researchers have made a breakthrough discovery about the development of rod and cone photoreceptors, the light-sensitive cells in the retina that initiate vision. The study found that the retinal protein Nrl acts as a 'molecular switch,' signaling cells to develop into rods rather than cones.
Research reveals CPY26 degrades retinoic acid to establish uneven distribution, crucial for normal embryonic development. Elevated RA levels in Cpy26 mutant mice lead to severe developmental defects, highlighting the enzyme's protective role.
Researchers at Albert Einstein College of Medicine found that Id2 gene is implicated in neuroblastoma development and underlies tumor growth. The study suggests developing drugs to counteract the Id2 gene may provide targeted treatment for neuroblastoma and other cancers.
Scientists have successfully implanted the lens of a sighted fish into cavefish, resulting in the growth of a normal eye. This breakthrough may provide new avenues for understanding the genetic factors involved in eye growth and development, potentially leading to improved treatments for certain forms of blindness. Further research is ...
Researchers found that a brief deprivation of vitamin A in developing chicken embryos can generate severe craniofacial deformities, which could be reversed with targeted protein treatments. The study suggests that carefully timed protein therapies in human fetuses might repair cleft palate and other birth defects.
Researchers have found that cells in the developing limb provide a key signaling molecule that defines motor neuron identity. The study reveals that motor and sensory neurons express the same genes, suggesting a coordinating role for the target region in constructing proper connections within the spinal cord.
Harvard Medical School researchers have isolated a gene, Crx, that plays a key role in photoreceptor development. The findings suggest that Crx could help prevent blindness in people with retinal disease by regulating the expression of genes unique to photoreceptors.
The company has validated the VEGF receptor as a key target in pathological angiogenesis and expects to submit an Investigational New Drug (IND) Application for clinical trials in cancer by the end of 1998. RPI.4610 has shown activity in multiple animal models, including inhibition of tumor growth and metastasis.
Researchers at Duke University Medical Center have used glowing jellyfish protein to study how cells transform from embryos to larvae in fruit flies. The studies shed light on how cells cinch shut during dorsal closure, a process comparable to neural tube closure in developing mammalian fetuses.
A team of researchers has solved a centuries-old puzzle in eye development by discovering that the embryo has a single eye field that normally separates into two. The study found that an inhibitory signal shuts off gene expression in the middle of the eye field, leading to cyclopia if this fails to happen.
