DNA methylation analysis of the cell free DNA from Retinoblastoma

ABSTRACT: Retinoblastoma (RB) is a primary intraocular cancer in infants and toddlers. Direct biopsy is contraindicated in RB due to the risks of provoking extraocular tumor spread. In this study, we demonstrated that DNA methylation profile can be obtained from the tumor-derived cell-free DNA in aqueous humor (AH) and is highly concordance with that directly from RB primary tumors. It is the first time to identify unique DNA methylation pattern from RB tumor before surgically removing the eye. We provde the evidence that DNA methylation from AH could not only be used for RB diagnosis, but also for the prognostic prediction and potential therapeutic targets by personalized approach.

Characterizing Local Extension of Retinoblastoma by Single-cell Transcriptomics

Project description:Retinoblastoma (RB) is the most prevalent ocular tumor of childhood whose extraocular invasion largely increase metastasis risk. Nevertheless, a single-cell characterization of RB local extension has been lacking. Here, we perform single-cell RNA sequencing (scRNA-seq) 4 RB samples (2 from intraocular and 2 from extraocular RB patients), and integrate public scRNA-seq datasets to characterize the local extension of RB at single-cell level.

Proteomics of aqueous humor for biomarkers discovery in retinoblastoma (pt2)

Project description:Background: Recent therapeutic advances have greatly improved the eye preservation rate in patients affected by retinoblastoma (RB), however local tumor control remains more difficult in the presence of resistant and/or relapsing retinal or vitreous disease. Thus, the identification of new biomarkers is crucial to design more effective treatment approaches. Recently, technological advances have allowed to safely recover aqueous humor (AH) from patients affected by RB undergoing local treatment. Methods: in order to identify specific proteins associated to active vitreous seeding, we have performed proteomic analysis of AH samples derived from patients affected by RB in different disease stages. Fifty-five AH samples were firstly included in this study. A new widened cohort was then used to validate the proteins identified in the previous discovery set. Results: a total of 808 and 630 proteins were identified in the two analysis, respectively. Five proteins resulted more expressed in the active vitreous seeding group: C19orf57, Girdin, SRFBP, GULP-1 and DCD. These proteins are involved in cytoskeleton regulation, tumor proliferation and growth, invasion and migration of cancer cells. Conclusion: reliable prognostic biomarkers are needed to guide RB management. Proteomic analysis of AH provide a unique opportunity to identify tumor associated biomarkers in patients with RB.

Gene therapy for glaucoma using a combination targeting multiple genes with CRISPR-CasRx

Project description:Glaucoma affects approximately 80 million individuals worldwide, a condition for which current treatment options are inadequate. The primary risk factor for glaucoma is elevated intraocular pressure, which is currently the only controllable treatment approach. Elevated intraocular pressure is determined by the balance between the secretion and outflow of aqueous humor (AH). Utilizing CRISPR Cas9 to disrupt the expression of the AQP1 protein, which decreases the ciliary AH secretion, resulted in an approximate 22% reduction in intraocular pressure. Nevertheless, the effectiveness of single-gene therapies is limited. To address this limitation, we conducted experiments using two mouse models of ocular hypertension. Our findings indicate that reducing the expression of the genes Rock1 and Rock2, which are associated with the outflow of AH at the trabecular meshwork (TM), as well as the genes Aqp1 and Adrb2, which are related to the generation of AH at the ciliary body (CB), can significantly reduce intraocular pressure and provide protection to the retina ganglion cells (RGCs), ultimately delaying disease progression. In addition, we elucidated the mechanisms by which the knockdown of Rock1 and Rock2, or Aqp1 and Adrb2, reduces the IOP and secures RGCs by single-cell sequencing.

Proteomic Profiling of Retinoblastoma-Derived Exosomes reveals potential biomarkers of vitreous seeding

Project description:Retinoblastoma (RB) is the most common tumor of the eye in early childhood. Despite recent advances in conservative treatment have greatly improved the visual outcome, local tumor control remain difficult in presence of massive vitreous seeding. Traditional biopsy has long been considered unsafe in RB, due to the risk of extraocular spread. Thus, the identification of new biomarkers is crucial to design safer diagnostic and more effective therapeutic approaches. Exosomes represent an interesting alternative to detect tumor-associated biomarkers. In this study we defined the protein signature of exosomes released by RB tumors (RBT) and vitreous seeding (RBVS) primary cell lines by high resolution mass spectrometry. A total of 5666 proteins were identified. Among these, 5223 and 3637 were expressed in exosome RBT and one RBVS group respectively.

Differentially expressed microRNAs in the aqueous humor of patients with exfoliation glaucoma or primary open-angle glaucoma

Project description:To better understand the molecular changes in the aqueous humor (AH) content with glaucoma, we analyzed the microRNA (miRNA) profiles of AH samples from patients with Primary Open Angle Glaucoma (POAG) and Exfoliation Glaucoma (XFG) compared to non-glaucoma controls.

The Constitutive Proteome of Human Aqueous Humor

Project description:Aqueous humor (AH) is the fluid in the anterior and posterior chambers of the eye that contains proteins regulating ocular homeostasis. Analysis of aqueous humor proteome is challenging mainly due to low sample volume and protein concentration. In this study, by utilizing state of the art technology, we performed Liquid-Chromatography Mass spectrometry (LC-MS/MS) analysis of 88 aqueous humor samples from subjects undergoing cataract surgery.

Plasma miRNome analysis from retinoblastoma patients reveals the size of the circulating miRNome, a tumor signature and new normalizers candidates.

Project description:In This work we analyzed the mirnome in plasma and corresponding extracellular vesicles (EVs) from 12 patients affected by retinoblastoma (Rb) a childhood intraocular malignant tumor, as well as from 12 healthy aged matched controls. Using hierarchical clustering with the detection score microarrays provide for each miRNA and we identified a plasma signature of 19 miRNAs in all Rb cases that were able to discriminate both cases from controls.
