Prasanna G, Dibas A, Yorio T
Invest Ophthalmol Vis Sci . 2001 Feb; 41(5):1142-8. PMID: 10752952
Purpose: To determine the cholinergic (carbachol, CCH) and adrenergic (norepinephrine, NE) modulation of Ca2+ response to endothelin-1 in human ciliary smooth muscle (HCSM) cells. Methods: Intracellular calcium levels were measured...

Bhatt H, Conner B, Prasanna G, Yorio T, Easom R
Biochem Pharmacol . 2000 Nov; 60(11):1655-63. PMID: 11077048
Previous studies utilizing inhibitors of the Ca(2+)/calmodulin-dependent protein kinase II (CaM kinase II) to address the role of this enzyme in insulin secretion have produced contradictory results. In the current...

Prasanna G, Dibas A, Finkley A, Yorio T
Exp Eye Res . 1999 Aug; 69(2):175-83. PMID: 10433854
Endothelins (ETs), potent vasoactive peptides, are present in many ocular tissues including the ciliary epithelium where active ET-1 is produced from the precursor Big ET-1 by a membrane-bound metalloprotease, endothelin-converting...

Dibas A, Prasanna G, Yorio T
J Ocul Pharmacol Ther . 1999 Jun; 15(3):241-50. PMID: 10385133
Phenylarsine oxide (PAO), a sulfhydryl modifying reagent and a widely used inhibitor for tyrosine phosphatases and endocytosis, was tested on the level of phosphorylation in human nonpigmented ciliary epithelial ocular...

Prasanna G, Dibas A, Brown K, Yorio T
J Ocul Pharmacol Ther . 1998 Nov; 14(5):401-12. PMID: 9811229
Previously, we have shown that tumor necrosis factor-alpha (TNF-alpha), a proinflammatory cytokine, increases the synthesis and release of endothelin-1 (ET-1), a potent vasoactive peptide from human non-pigmented ciliary epithelial (HNPE)...

Prasanna G, Dibas A, Tao W, White K, Yorio T
Exp Eye Res . 1998 Jun; 66(1):9-18. PMID: 9533826
Endothelins (ET) are potent vasoactive peptides present in many ocular structures and are formed from precursor Big endothelins (Big ET-1) by the action of an endothelin-converting enzyme (ECE). ET-1 is...

Tao W, Prasanna G, Dimitrijevich S, Yorio T
Curr Eye Res . 1998 Feb; 17(1):31-8. PMID: 9472468
Purpose: To identify which endothelin receptor subtype is expressed and is functional in the human ciliary body and trabecular meshwork, tissues that regulate aqueous humor dynamics. Methods: Immunocytochemistry was used...
