mA and beyond: RNA modifications shaping angiogenesis.

RNA modifications are crucial post-transcriptional processes that significantly influence gene expression, RNA stability, nuclear transport, and translational capacity. Angiogenesis, the formation of new blood vessels, is a physiological process that is dysregulated in many pathological conditions, including ocular diseases, immune disorders, and cancer. In this review, we compile the current understanding of the intricate relationship between various RNA modifications and angiogenic mechanisms, spotlighting emerging evidence that underscore their pivotal regulatory roles in both physiological and pathological angiogenesis.

Ultra-processed foods consumption and risk of age-related eye diseases: a prospective cohort study with UK biobank.

Purpose: Consumption of ultra-processed foods (UPF) has been associated with increased risks of various age-related diseases. However, the potential association between UPF consumption and age-related eye diseases (AREDs) remains unclear. We aim to assess the associations between consumption of UPF and risk of AREDs including age-related macular degeneration (AMD), cataract and glaucoma.

Factors influencing parental fatigue in children with retinoblastoma based on the unpleasant symptoms theory.

Parents of children with retinoblastoma, the most common primary ocular malignant tumour in childhood, bear a heavy caregiving burden and are very susceptible to fatigue. However, little is known about their current status of fatigue and factors influencing fatigue; therefore,this study, based on the theory of unpleasant symptoms, and included 317 parents of children with retinoblastoma in China, whose general demographic data were collected, and on whom the fatigue severity scale (FSS), the generalized anxiety disorder (GAD-7) and 2-item patient health questionnaire (PHQ-2) were administered, from 9 March to 1 June 2020. The parents' FSS score and fatigue incidence were 4.

Exploring the interplay between addiction and time perception: A systematic review and meta-analysis.

Prior studies have investigated the immediate impacts of substances on temporal perception, the impact of temporal outlook, and the consequences of modified temporal perception on addictive behaviors. These inquiries have provided valuable perspectives on the intricate associations between addiction and time perception, enriching the groundwork for forthcoming research and therapeutic strategies. This comprehensive review aims to further explore intricate correlation among diverse addictive substances-namely alcohol, cannabis, nicotine, opioids-and non-substance addictions such as internet gaming, elucidating their influence on temporal perception.

Correlation Analysis of Apparent Diffusion Coefficient Histogram Parameters and Clinicopathologic Features for Prognosis Prediction in Uveal Melanoma.

Purpose: To investigate the correlation between apparent diffusion coefficient (ADC) histograms and high-risk clinicopathologic features related to uveal melanoma (UM) prognosis.

Methods: This retrospective study included 53 patients with UM who underwent diffusion-weighted imaging (DWI) between August 2015 and March 2024. Axial DWI was performed with a single-shot spin-echo echo-planar imaging sequence.

Single-cell sequencing depicts tumor architecture and empowers clinical decision in metastatic conjunctival melanoma.

Conjunctival melanoma (CoM) is a potentially devastating tumor that can lead to distant metastasis. Despite various therapeutic strategies for distant metastatic CoM, the clinical outcomes remain unfavorable. Herein, we performed single-cell RNA sequencing (scRNA-seq) of 47,017 cells obtained from normal conjunctival samples (n = 3) and conjunctival melanomas (n = 7).

An Overview of Optic Pathway Glioma With Neurofibromatosis Type 1: Pathogenesis, Risk Factors, and Therapeutic Strategies.

Optic pathway gliomas (OPGs) are most predominant pilocytic astrocytomas, which are typically diagnosed within the first decade of life. The majority of affected children with OPGs also present with neurofibromatosis type 1 (NF1), the most common tumor predisposition syndrome. OPGs in individuals with NF1 primarily affect the optic pathway and lead to visual disturbance.

Beneficial mechanisms of dimethyl fumarate in autoimmune uveitis: insights from single-cell RNA sequencing.

Background: Dimethyl fumarate (DMF) is a fumaric acid ester that exhibits immunoregulatory and anti-inflammatory properties. However, the function of DMF in autoimmune uveitis (AU) is incompletely understood, and studies comprehensively exploring the impact of DMF on immune cells are still lacking.

Methods: To explore the function of DMF in uveitis and its underlying mechanisms, we conducted single-cell RNA sequencing (scRNA-seq) on the cervical draining lymph node (CDLN) cells of normal, experimental autoimmune uveitis (EAU), and DMF-treated EAU mice.

Recent progress in retinoblastoma: Pathogenesis, presentation, diagnosis and management.

Retinoblastoma, the primary ocular malignancy in pediatric patients, poses a substantial threat to mortality without prompt and effective management. The prognosis for survival and preservation of visual acuity hinges upon the disease severity at the time of initial diagnosis. Notably, retinoblastoma has played a crucial role in unraveling the genetic foundations of oncogenesis.

Novel insights into TCR-T cell therapy in solid neoplasms: optimizing adoptive immunotherapy.

Adoptive immunotherapy in the T cell landscape exhibits efficacy in cancer treatment. Over the past few decades, genetically modified T cells, particularly chimeric antigen receptor T cells, have enabled remarkable strides in the treatment of hematological malignancies. Besides, extensive exploration of multiple antigens for the treatment of solid tumors has led to clinical interest in the potential of T cells expressing the engineered T cell receptor (TCR).

Transketolase promotes MAFLD by limiting inosine-induced mitochondrial activity.

Metabolic dysfunction-associated fatty liver disease (MAFLD) has a global prevalence of about 25% and no approved therapy. Using metabolomic and proteomic analyses, we identified high expression of hepatic transketolase (TKT), a metabolic enzyme of the pentose phosphate pathway, in human and mouse MAFLD. Hyperinsulinemia promoted TKT expression through the insulin receptor-CCAAT/enhancer-binding protein alpha axis.

Kurarinone regulates Th17/Treg balance and ameliorates autoimmune uveitis via Rac1 inhibition.

Introduction: Autoimmune uveitis (AU) is a severe intraocular autoimmune disorder with a chronic disease course and a high rate of blindness. Kurarinone (KU), a major component of the traditional Chinese medicine Sophorae Flavescentis Radix, possesses a wide spectrum of activities and has been used to treat several inflammation-related diseases.

Objective: We aimed to investigate the effects of KU on AU and its modulatory mechanisms.

High-risk histopathologic features in local advanced conjunctival melanoma.

Purpose: To identify high-risk histopathologic and molecular features of local recurrence, nodal metastasis, distant metastasis (DM) and disease-specific death (DSD) in conjunctival melanoma (CoM).

Methods: Ninety patients with pathologically diagnosed CoM between 2008 and 2023 were enrolled. Immunohistochemistry staining of BRAF, NRAS, CD117, PD-1 and PD-L1 was performed in 65 and 45 patients, respectively.

Genetic landscape and prognosis of conjunctival melanoma in Chinese patients.

The Use of rAAV2-RB1-Mediated Gene Therapy in Retinoblastoma.

Purpose: Retinoblastoma (RB) is a life-threatening malignancy that arises from the retina and is activated upon homozygous inactivation of the tumor suppressor RB1. Gene therapy targeting RB1 is an effective strategy to treat RB. However, it is difficult to target the RB1 gene by site-specific repair, with up to 3366 gene mutation sites identified in RB1.
