To investigate whether we can identify different patterns of inflammation in the aqueous humor of a uveal melanoma (UM)-containing eye, and whether these are related to prognosis.
Uveal melanoma is an aggressive intraocular malignancy that often exhibits low immunogenicity. Metastatic uveal melanoma samples frequently exhibit monosomy 3 or deficiency. In this study, we used bioinformatic methods to investigate the immune infiltration of uveal melanoma samples in public datasets. We first performed Gene Set Enrichment/Variation Analyses to detect immunological pathways that are altered in tumors with monosomy 3 or deficiency. We then conducted an unsupervised clustering analysis to ...
The NCCN Guidelines for Uveal Melanoma include recommendations for staging, treatment, and follow-up of patients diagnosed with uveal melanoma of the choroid or ciliary body. In addition, because distinguishing between uveal melanoma and benign uveal nevi is in some cases difficult, these guidelines also contain recommendations for workup of patients with suspicious pigmented uveal lesions, to clarify the tests needed to distinguish between those who should have further workup and treatment for uveal melano...
Uveal melanomas are the most common primary intraocular malignant tumors in adults, associated with a high metastasis rate and a low 5-year survival rate. It is a clinic urgency and importance to identify prognostic factors for UVMs.
Uveal melanoma is a common primary intraocular malignancy accompanied by high mortality. Previous evidence has highlighted the implication of microRNAs (miRNAs) and long noncoding RNAs (lncRNAs) in uveal melanoma. Accordingly, we further uncovered the possible role of lncRNA plasmacytoma variant translocation 1 gene (PVT1) and microRNA-17-3p (miR-17-3p) in uveal melanoma.
MEK inhibitors (MEKi) demonstrate anti-proliferative activity in patients with metastatic uveal melanoma, but responses are short-lived. In the present study, we evaluated the MEKi trametinib alone and in combination with drugs targeting epigenetic regulators, including DOT1L, EZH2, LSD1, DNA methyltransferases and histone acetyltransferases. The DNA methyltransferase inhibitor (DNMTi) decitabine effectively enhanced the anti-proliferative activity of trametinib in cell viability, colony formation, and 3D o...
MicroRNA-34a (miR-34a) has been implicated in many biological processes. It is downregulated in uveal melanoma, and introduction of miR-34a inhibits the proliferation and migration of uveal melanoma cells. Leucine-rich repeat-containing G protein-coupled receptor 4 (LGR4) is a novel target of miR-34a identified first in retinal pigment epithelial cells. In this study, we sought to evaluate the interaction of miR-34a and LGR4 in uveal melanoma and its downstream mechanisms.
Uveal melanoma is an aggressive malignancy that originates from melanocytes in the eye. Even if the primary tumor has been successfully treated with radiation or surgery, up to half of all UM patients will eventually develop metastatic disease. Despite the common origin from neural crest-derived cells, uveal and cutaneous melanoma have few overlapping genetic signatures and uveal melanoma has been shown to have a lower mutational burden. As a consequence, many therapies that have proven effective in cutaneo...
Metastatic uveal melanoma (UM) has a very poor prognosis and no effective therapy. Despite remarkable advances in treatment of cutaneous melanoma, UM remains recalcitrant to chemotherapy, small-molecule kinase inhibitors, and immune-based therapy.
Uveal melanomas are associated with characteristic genetic changes. Germline mutations in mismatch repair (MMR) genes and microsatellite instability have been implicated in the development of numerous malignant neoplasms such as colon and ovarian cancers. The frequency of MMR defects in uveal melanomas has yet to be determined.
This study explored the effects of the metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) on the development of uveal melanoma. Moreover, the role of the MALAT1/microRNA-608 (miR-608)/homeobox C4 (HOXC4) axis was assessed by evaluating the proliferation, invasion, and migration, as well as the cell cycle distribution of uveal melanoma after knocking down MALAT1 or HOXC4 and/or overexpression of miR-608 in uveal melanoma cells (MUM-2B and C918). Moreover, the effects of the MALAT1/miR-608/HOXC4...
Drug-like compounds are most of the time denied approval and use owing to the unexpected clinical side effects and cross-reactivity observed during clinical trials. These unexpected outcomes resulting in significant increase in attrition rate centralizes on the selected drug targets. These targets may be disease candidate proteins or genes, biological pathways, disease-associated microRNAs, disease-related biomarkers, abnormal molecular phenotypes, crucial nodes of biological network or molecular functions....
Uveal melanoma is the most common intraocular primary malignancy in adults and has been considered a fatal disease for decades. Optogenetics is an emerging technique that can control the activation of signaling components via irradiation with visible light. The clinical translation of optogenetics has been limited because of the need for surgical implantation of electrodes and relatively shallow tissue penetration. As visible light easily penetrates the eyes, we hypothesized that an optogenetics approach ca...
Many anticancer drugs have been developed for clinical usage till now, but the major problem is the development of drug-resistance over a period of time in the treatment of cancer. Anticancer drugs produce huge adverse effects, ultimately leading to death of the patient. Researchers have been focusing on development of novel molecules with higher efficacy and lower toxicity; the anti-malarial drug artemisinin and its derivatives have exhibited cytotoxic effects.
There has been speculation on the pathogenesis of unilateral multifocal uveal melanoma, but there remains no convincing explanation. Genetic analysis suggests that unilateral multifocal uveal melanoma may represent intraocular metastasis with increased risk of systemic metastasis.
To investigate whether early detection and treatment of uveal melanoma by screening was associated with a lower mortality rate.
Since more than a decade, pharmaceutical researchers endeavor to develop an effective, safe and target-specific drug delivery system to potentiate the therapeutic actions and reduce the side effects. The conventional drug delivery systems (DDSs) show the improvement in the lifestyle of the patients suffering from non-communicable diseases, autoimmune diseases but sometimes, drug resistance developed during the treatment is a major concern for clinicians to find an alternative and more advanced transport sys...
The drug development pipeline has stalled because of the difficulty in identifying new drug targets while minimizing off-target effects. Computational methods, such as the use of metabolic network reconstructions, may provide a cost-effective platform to test new hypotheses for drug targets and prevent off-target effects. Here, we summarize available methods to identify drug targets and off-target effects using either reaction-centric, gene-centric, or metabolite-centric approaches with genome-scale metabol...
Studies on uveal melanomas (UMs) have demonstrated the prognostic value of 8q gain and monosomy 3, but the prognosis of UMs with partial deletion of chromosome 3 remains to be defined.
To study the morphological features of the microenvironment of a tumor nodule in the eyes with uveal melanoma, focusing on mast cells.
To analyze the activation of NFκB1/p50 in the inflammatory and non-inflammatory environment of uveal melanoma and its association with clinicopathological factors and patient outcome.
Controversy exists regarding the best method for biopsy of uveal melanoma. We describe our transvitreal technique and evaluate the safety of this technique as well as the efficacy for obtaining sample for prognostic genetic profiling.
Combination chemotherapy with defined ratio and sequence of drug release is a clinically established and effective route to treat advanced solid tumors. In this context, a growing body of literature demonstrates the potential of hydrogels constructed with chemically modified polysaccharides as depots for controlled release of chemotherapeutics. Identifying the appropriate modification in terms of physicochemical properties of the functional group and its degree of substitution (χ) to achieve the desired re...
