Disclosed herein are nucleic acid molecules comprising a nucleotide sequence of sVEGF-2, proteins encoded by those sequences and antibodies that bind to the protein. Also disclosed are methods for inhibiting or enhancing expression or activity of sVEGFR-2 and methods for inhibiting graft rejection, particularly cornea graph rejection. Also described are methods for inhibiting lymphangiogenesis and lymphatic endothelial cell proliferation by administering an effective amount of sVEGFR-2 and methods for treating lymphedema by inhibiting the activity of sVEGFR-2.

The results presented herein demonstrate the specific expression of CCR3 in CNV endothelial cells in humans with AMD, and despite the expression of its ligands, eotaxin-1, -2, and -3, neither eosinophils nor mast cells are present in human CNV. The genetic or pharmacological targeting of CCR3 or eotaxins as disclosed herein inhibited injury-induced CNV in mice. CNV suppression by CCR3 blockade was due to direct inhibition of endothelial cell proliferation, and was uncoupled from inflammation as it occurred in mice lacking eosinophils or mast cells and was independent of macrophage and neutrophil recruitment. CCR3 blockade was more effective at reducing …

Ocular coloboma is a sight-threatening malformation caused by failure of the choroid fissure to close during morphogenesis of the eye, and is frequently associated with additional anomalies, including microphthalmia and cataracts. Although Hedgehog signaling is known to play a critical role in choroid fissure closure, genetic regulation of this pathway remains poorly understood. Here, we show that the transcription factor Sox11 is required to maintain specific levels of Hedgehog signaling during ocular development. Sox11-deficient zebrafish embryos displayed delayed and abnormal lens formation, coloboma, and a specific reduction in rod photoreceptors, all of which could be rescued by treatment with the …

Activation of the phosphoinositide (PI) cycle generates the second messengers that control various aspects of cellular signaling. We have previously shown that two PI cycle enzymes, type II phosphatidylinositol 5-phosphate 4-kinase (PIPK IIα) and phosphoinositide 3-kinase (PI3K), are activated through light stimulation. In our earlier studies, we measured enzyme activities, instead of directly measuring the products, due to lack of sensitive analytical techniques. Cells have very low levels of PIs, compared to other lipids, so special techniques and sensitive analytical instruments are necessary for their identification and quantification. There are also other considerations, such as different responses in different cell …

Novel withanolide chemical genetic probes identify the in vivo binding target of withaferin A, which is the intermediate filament type III protein vimentin. In addition, a withanolide-based small molecule screening method screens drug candidates that target intermediate filament type III proteins. The method includes introducing a tagged linker covalently bonded to the withanolide molecule to form a withanolide probe. Better or alternative small molecule compounds as potential drug candidates can be generated based on their likely affinity for the determined binding site in vimentin. The affinity labeled withanolide can also be used to find intermediate filament-associated proteins using chemical proteomics …

Age-related macular degeneration (AMD) is a principal cause of blindness in the United States and other industrialized nations. An estimated 10 million Americans are afflicted with AMD, which is comparable in scope to the 12 million living with cancer, or the 5 million with Alzheimer’s disease. The prevalence of AMD steadily increases with age, affecting 2% of the population at age 40, and one in four people by age 80. For reasons that are not fully understood, AMD is more common in lightly-pigmented and female populations. Treatment of AMD is largely an unmet need: There are no FDA approved therapies …
