Exploring the Mechanism of Curcumin on Retinoblastoma Based on Network Pharmacology and Molecular Docking. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2022:2407462. [PMID: 35911143 PMCID: PMC9325604 DOI: 10.1155/2022/2407462] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/12/2022] [Revised: 06/20/2022] [Accepted: 06/25/2022] [Indexed: 11/17/2022]
Abstract
Background Curcumin shows great effects of inhibiting tumor cell proliferation, inducing apoptosis, inhibiting tumor metastasis, and inhibiting angiogenesis on a variety of tumors. However, the biological activity and possible mechanisms of curcumin in the treatment of retinoblastoma have not been fully elucidated. This study explored the potential therapeutic targets and pharmacological mechanisms of curcumin against retinoblastoma based on network pharmacology and molecular docking. Methods The genes corresponding to curcumin targets were screened from the HERB, PharmMapper, and SwissTargetPrediction databases. Protein-protein interaction (PPI) networks were constructed for the intersecting targets in the STRING database. Cytoscape 3.7.0 was used for network topology analysis and screening of important targets. R 4.1.0 software was used for Gene Ontology (GO) function enrichment and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis of intersection targets. The molecular structures of curcumin and core target proteins were obtained from PubChem and PDB databases, and the two were preprocessed and molecularly docked using AutoDockTools and PyMOL software. Results Through network data mining, we obtained 504 curcumin targets and 966 retinoblastoma disease targets, and 44 potential targets for curcumin treatment of retinoblastoma were obtained by mapping. Three core targets were obtained from network topology analysis. 462 biological processes, 21 cellular compositions, and 34 molecular functions were obtained by GO enrichment analysis. KEGG pathway analysis revealed 94 signaling pathways, mainly involving chemical carcinogenesis-receptor activation, chemical carcinogenesis-reactive oxygen species, viral carcinogenesis, Th17 cell differentiation, etc. The molecular docking results indicated that the binding energy of curcumin to the core targets was less than 0 kJ mol-1, among which the binding energy of RB1 and CDKN2A to curcumin was less than -5 kJ mol-1 with significant binding activity. Conclusion Based on molecular docking technology and network pharmacology, we initially revealed that curcumin exerts its therapeutic effects on retinoblastoma with multitarget, multipathway, and multibiological functions, providing a theoretical basis for subsequent studies.

Int J Ophthalmol 2021; 14:497-503. [PMID: 33875938 DOI: 10.18240/ijo.2021.04.03] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2020] [Accepted: 02/19/2021] [Indexed: 11/23/2022] Open
Abstract
AIM To explore the effect of the Andrographis paniculata (A. paniculata) polysaccharide on the proliferation and apoptosis of human retinoblastoma (RB) Y79 cells and its mechanism. METHODS The refined A. paniculata polysaccharide was obtained using techniques such as water extraction, ethanol precipitation, and decompression concentration. The inhibition effect of the A. paniculata polysaccharide on the proliferation of Y79 cells was detected by cell proliferation assay. Flow cytometry was used for the detection of cell apoptosis rate and cycle change. Real-time qunatitative polymerase chain reaction (RT qPCR)and Western blotting were used to detect the expression of cell apoptosis signal pathway-related factors (caspase-3, caspase-8, and caspase-9) and cell cycle signal pathway-related factors (CDK1 and cyclinB1) at the transcriptional and translational levels. RESULTS Infrared and ultraviolet spectrum scanning showed that the extracted drug was a polysaccharide with high purity. After being treated with different concentrations of A. paniculata polysaccharide for different periods of time, the Y79 cells showed different degrees of proliferation inhibition. Flow cytometric observations showed that the cell apoptosis rate and the proportion of cells blocked in the G2/M phase were significantly increased after A. paniculata polysaccharide treatment. Further analysis revealed that the mRNA and protein expression of caspase-3, caspase-8, and caspase-9 in the A. paniculata polysaccharide treatment groups increased significantly compared with that in the control groups, while the expression of CDK1 and cyclinB1 decreased significantly. CONCLUSION The A. paniculata polysaccharide could inhibit the proliferation and induce apoptosis of Y79 cells. Its possible mechanism is via the upregulation of caspase-3, caspase-8, and caspase-9 expression in the cell apoptotic signaling pathway and the downregulation of CDK1 and cyclinB1 expression in the cell cycle signaling pathway.

Abstract
Identifying patients with a genetic predisposition for developing malignant tumors has a significant impact on both the patient and family. Recognition of genetic predisposition, before diagnosing a malignant pathology, may lead to early diagnosis of a neoplasia. Recognition of a genetic predisposition syndrome after the diagnosis of neoplasia can result in a change of treatment plan, a specific follow-up of adverse treatment effects and, of course, a long-term follow-up focusing on the early detection of a second neoplasia. Responsible for genetic syndromes that predispose individuals to malignant pathology are germline mutations. These mutations are present in all cells of conception, they can be inherited or can occur de novo. Several mechanisms of inheritance are described: Mendelian autosomal dominant, Mendelian autosomal recessive, X-linked patterns, constitutional chromosomal abnormality and non-Mendelian inheritance. In the following review we will present the most important genetic syndromes in pediatric oncology.

Abstract
Introduction Retinoblastoma (Rb) is the most common intraocular malignant tumor of childhood. The different modes of Rb presentation comprise proptosis, anterior chamber inflammatory signs, spontaneous hyphema, secondary glaucoma, and strabismus. The primary aim of this study was to investigate the different clinical presentations and stages of Rb that may help in early detection and timely diagnosis to prevent the advancement of the disease and increase rates of survival in children. Materials and methods This was a descriptive cross-sectional study conducted between December 2019 and May 2020 over a period of six months at a tertiary care hospital in Karachi, Pakistan. The sample size included 68 eyes of children with lesions of Rb at the time of presentation to the hospital. Brightness scans (B-scans), computed tomography (CT) scans, and magnetic resonance imaging (MRI) were performed. The International Intraocular Retinoblastoma Classification (IIRC) was used to stage each eye. In case of enucleation (if necessary) of the eye, the biopsy was performed to evaluate the histological features of cancer. All statistical analysis was performed using Statistical Package for Social Sciences version 17.0 (IBM Corp., Armonk, New York). Results The mean age of the children was 3.21 ± 1.75 years. Leukocoria was the most common clinical presentation observed in more than half (n = 35, 51.47%) of the sample population followed by proptosis reported in nearly two-fifths (n = 25, 36.76%), strabismus and phthisis bulbi observed in equal proportions (n = 3, 4.41%), and hypopyon documented in a minor proportion (n = 2, 2.94%) of patients. Regarding stages of the Rb disease, the most common stages were observed to be stage C and stage E. Conclusions This study concludes that the early detection of Rb is possible through a better understanding of presenting features of the disease. It can prevent the progression of the disease to the advanced stages and decrease morbidity and mortality. The early detection of Rb can be made possible through the examination of red reflex on the regular check-ups of children as leukocoria is the most common clinical presentation.

Abstract
13q syndrome is a chromosomal abnormality in which there is a pathognomic deletion of the genetic material on the long arm (q) of chromosome 13. Phenotypes of this syndrome are variable depending on the location of the deleted segment. The main manifestations of the syndrome include mental retardation, craniofacial dysmorphism, and increased susceptibility to tumors. We report a unique case of recurrent sporadic bilateral retinoblastoma (Rb) in a four-year-old boy carrying 13q (q12q14) interstitial deletion, which was treated successfully via enucleation and chemotherapy. Where most patients with familial Rb receive a single mutated Rb1 allele as the ‘first hit’, a small number of patients encounter interstitial deletion of the long arm of chromosome 13, resulting in the loss of the tumor suppressor Rb1 gene and presenting as sporadic cases.

Abstract
Masquerade syndromes are disorders occurring with intraocular inflammation misdiagnosed as uveitis. The underlying causes may be benign or malignant conditions, and one of the most important diagnoses to take into consideration in children is retinoblastoma. We present two cases with uncertain early misdiagnosis whose definite diagnosis eventually was retinoblastoma.

Abstract
RB is a primarily pediatric cancer arising from the retina, initiated by biallelic loss of the RB1 gene. We report five children with bilateral RB (n = 3), extra-ocular disseminated RB, or disseminated relapsed RB, who were treated with tandem high-dose chemotherapy and autologous stem cell rescue. All patients received at least 2.2 × 10(6) /kg CD34(+) (median, 3.9 × 10(6) /kg) cells. The preparative regimen for course 1 was carboplatin, thiotepa, etoposide, and for course 2, CM and melphalan. ANC of at least 0.5 × 10(9) /L occurred at a median of 11 days (range, 10-12) and 15 days (range, 12-16) after the first and second procedure, respectively. Platelet engraftment occurred at a median of 13 days (range, 12-17) and 15 days (range, 14-22) after the first and second procedure, respectively. All of the five patients treated remain alive and disease free at the last follow-up time, ranging between 21 and 44 months after completion of autologous transplant. Additional therapy was required in one patient, in whom enucleation had to be performed because of early disease relapse, refractory to local therapy. Intensification of chemotherapy with repeated high-dose chemotherapy and autologous rescue appears an acceptable choice in selected cases with bilateral or extra-ocular disease, either recurrent or refractory.
