Differential expression of transforming growth factor-β isoforms in bullous keratopathy corneas
نویسندگان
چکیده
PURPOSE The aim of this study was to investigate transcriptional activities of genes encoding transforming growth factor (TGF)-beta isoforms in bullous keratopathy corneas. METHODS The study group consisted of 45 patients with bullous keratopathy (22 females and 23 males). The control group included 45 corneal donors (21 females and 24 males). Quantification of TGF-beta1, TGF-beta2, and TGF-beta3 mRNAs was performed by real-time quantitative reverse transcription PCR (QRT-PCR). RESULTS TGF-beta1, TGF-beta2, and TGF-beta3 mRNAs were detected in both normal and pseudophakic bullous keratopathy (PBK) corneas. We found significantly lower transcriptional activity of TGF-beta3 mRNA in bullous keratopathy corneas compared to normal tissues. TGF-beta1 and TGF-beta2 expressions were at the same level in both PBK and healthy corneas. CONCLUSIONS Downregulation of TGF-beta3 gene expression may play a significant role in molecular changes observed in bullous keratopathy.

Transforming growth factor betas (TGF?s) are one of the most widespread and versatile cytokines. The three mammalian TGF? isoforms, ?1, ?2, and ?3, and their receptors regulate proliferation of neuronal precursors as well as survival and differentiation in neurons of developing and adult nervous system. Functions of TGF?s has a wide spectrum ranging from regulating cell proliferation and differ...

Background: TGF-β isoforms play crucial roles in diverse cellular processes. Therefore, targeting and inhibiting TGF-β signaling pathway provides a potential therapeutic opportunity. TGF-β isoforms bind and bring the receptors (TβRII and TβRI) together to form a signaling complex in an ordered manner. Objectives: Herein, an antagonistic variant of TGF-β (AnTβ)...

It has been shown in animal models that matrix metalloproteinases (MMPs) and their inhibitors (TIMPs) are responsible for remodelling and neovascularization of the diseased cornea. Under normal conditions, MMPs are expressed at relatively low levels, which may increase in case of different corneal diseases. In this paper we have investigated gene expression of matrix metalloproteinase 2, matrix...
