Changes of peripheral blood Th cytokines in acute anterior uveitis and their relationships with recurrence.

Acute anterior uveitis (AAU) can cause great pain to patients. Th cytokines in peripheral blood are significantly changed in these patients, including serum interleukin-23 (IL-23), interleukin-17 (IL-17), interleukin-4 (IL-4), interferon-γ (IFN-γ), tumor necrosis factor-α (TNF-α) and transforming growth factor-β1 (TGF-β1) increase. However, the relationship between Th cytokines and recurrence of AAU is still unclear.

Downregulation of glycoprotein non-metastatic melanoma protein B prevents high glucose-induced angiogenesis in diabetic retinopathy.

Diabetic retinopathy (DR), a microvascular complication characterized by abnormal angiogenesis, is the most common reason for irreversible blindness. Glycoprotein non-metastatic melanoma protein B (GPNMB), as a transmembrane protein, was found to be associated with angiogenesis. This study aims to investigate the role of GPNMB in DR.

Bioinformatics analysis and identification of hub genes and immune-related molecular mechanisms in chronic myeloid leukemia.

Background: Chronic myeloid leukemia (CML) is a malignant hyperplastic tumor of the bone marrow originating from pluripotent hematopoietic stem cells. The advent of tyrosine kinase inhibitors (TKIs) has greatly improved the survival rate of patients with CML. However, TKI-resistance leads to the disease recurrence and progression.

RNA-binding proteins as drivers of AML and novel therapeutic targets.

Acute myeloid leukemia (AML) is a group of genetically complex and heterogeneous invasive hematological malignancies with a low 5-year overall survival rate of 30%, which highlights the urgent need for improved treatment measures. RNA-binding proteins (RBPs) regulate the abundance of isoforms of related proteins by regulating RNA splicing, translation, stability, and localization, thereby affecting cell differentiation and self-renewal. It is increasingly believed that RBPs are essential for normal hematopoiesis, and RBPs play a key role in hematological tumors, especially AML, by acting as oncogenes or tumor suppressors.

m(6)A Modification of lncRNA NEAT1 Regulates Chronic Myelocytic Leukemia Progression miR-766-5p/CDKN1A Axis.

Background: Chronic myeloid leukemia (CML) is an acquired hematopoietic stem malignant disease originating from the myeloid system. Long non-coding RNAs (lncRNAs) have been widely explored in cancer tumorigenesis. However, their roles in CML remain largely unclear.

Celastrol Regulates the Secretion of Interleukin-17 in Patients with Sympathetic Ophthalmia Through Signal Transducer and Activator of Transcription 3.

The excessive secretion of interleukin (IL)-17 contributes to the pathological process of sympathetic ophthalmia (SO). Celastrol is a naturally active product and exhibits an immunosuppressive effect. However, whether the supplementation of celastrol relieves SO remains unclear.

The role of the inflammasomes in the pathogenesis of uveitis.

Uveitis is a diverse group of sight-threatening intraocular inflammatory diseases usually causing eye redness, pain, blurred vision, and sometimes blindness. Although the exact pathogenesis of uveitis is not yet clear, accumulating evidences have shown that an imbalanced regulation of immune responses caused by a combination of genetic and environmental factors are implicated in the pathogenesis of this disease. As critical regulators of inflammation, inflammasomes have been assumed to play a role in the pathogenesis of uveitis.

Optimization of urinary small extracellular vesicle isolation protocols: implications in early diagnosis, stratification, treatment and prognosis of diseases in the era of personalized medicine.

Extracellular vesicles isolation from urine was severely interfered by polymeric Tamm-Harsefall protein due to its ability to entrap exosome. Studies had been reported to optimize the extraction of urine extracellular vesicles by using reducing agents, surfactants, salt precipitation or ultrafiltration, but rarely based on highly specific purification methods. We optimized the density gradient centrifugation method for the isolation of urinary small extracellular vesicles (sEV) and compared seven differential centrifugation protocols to obtain the high-yield and high-purity sEV isolation procedures.

Circular RNA (circ-0075804) promotes the proliferation of retinoblastoma via combining heterogeneous nuclear ribonucleoprotein K (HNRNPK) to improve the stability of E2F transcription factor 3 E2F3.

It is growingly recognized that messenger RNAs (mRNAs) are important regulators of various cancers. However, there are few reporters about the function of E2F3 in retinoblastoma (RB), which needs more exploration. In addition, the circRNA circ-0075804 was derived from the E2F3 host gene.

Inhibition of Proteasome Activity Upregulates IL-6 Expression in RPE Cells through the Activation of P38 MAPKs.

Purpose: As far as we know, during the development of age-related macular degeneration (AMD), the activity of proteasome in retinal pigment epithelium cells (RPE) gradually decreases. And a lot of research has shown that age-related macular degeneration is closely related to inflammation and autoimmune. Moreover, there are many cytokines (CKs) involved in the course of inflammation.

Sulcus Fixation of Foldable Intraocular Lenses Guided by Ultrasound Biomicroscopy.

Background. To evaluate the clinical efficacy of suture fixation of foldable intraocular lens (IOL) in ciliary sulcus guided by ultrasound biomicroscopy (UBM). Methods.

Impairment of the ubiquitin-proteasome pathway in RPE alters the expression of inflammation related genes.

The ubiquitin-proteasome pathway (UPP) plays an important role in regulating gene expression. Retinal pigment epithelial cells (RPE) are a major source of ocular inflammatory cytokines. In this work we determined the relationship between impairment of the UPP and expression of inflammation-related factors.

Upregulation of DR3 expression in CD4⁺ T cells promotes secretion of IL-17 in experimental autoimmune uveitis.

Lutein and zeaxanthin supplementation reduces H2O2-induced oxidative damage in human lens epithelial cells.

Purpose: Epidemiological studies suggest that dietary intake of lutein and zeaxanthin is inversely related to the risk for senile cataract. The objectives of this work were to investigate the mechanisms by which these nutrients provide anti-cataract effects. We evaluated their modulation of oxidative damage in human lens epithelial cells (HLEC) and their interaction with intracellular glutathione (GSH).
