A pan-cancer analysis of RGR opsin expression and its downregulation associated with poor prognosis in glioma
Neoplasma. 2023 Oct;70(5):683-696. doi: 10.4149/neo_2023_230617N317.ABSTRACTRetinal G protein-coupled receptor (RGR) serves a retinal photoisomerase function to mediate retinoid metabolism and visual chromophore regeneration in the human eyes. Retinoids display critical functions in cell proliferation, differentiation, and apoptosis. Abnormal retinoid metabolism may contribute to tumor development. However, in human tumor tissues, the expression of RGR remains uncharacterized. Herein, we performed the analysis of RGR expression in 620 samples from 24 types of tumors by immunohistochemistry (IHC) and 33 cancer types from th...

Brain metastasis from esophageal squamous cell carcinoma: a clinical review of 30 cases
This study aimed to retrospectively evaluate the treatment strategies and possible prognostic factors in patients with brain metastases (BMs) from esophageal squamous cell carcinoma (ESCC). We retrospectively reviewed 30 patients with BMs from ESCC who were treated at our center between November 2011 and January 2022. Clinicopathological characteristics and clinical outcomes were analyzed. The median follow-up time was 2 (range, 0.5-33) months. The median survival time after diagnosis of BMs was 2 months. The 1-year overall survival (OS) rate was 13.6%. The OS was better in patients with intracranial benefit. Multivariate ...

ΔNp63 is regulated by insulin/IGF-1 signaling in normal basal/progenitor mammary cells and in luminal-type breast cancer cells
Neoplasma. 2023 Oct;70(5):621-632. doi: 10.4149/neo_2023_230719N376.ABSTRACTBreast cancers are a heterogeneous group of tumors classified according to their histological growth patterns and receptor expression characteristics. Intratumor heterogeneity also exists, with subpopulations of cells with different phenotypes found in individual cancers, including cells with stem or progenitor cell properties. At least two types of breast cancer stem cells (CSCs) exist, the epithelial and the basal/mesenchymal subtypes, although how these phenotypes are controlled is unknown. ΔNp63 is a basal cell marker and regulator of stem/pro...

RASSF1A promotes radiosensitivity in nasopharyngeal carcinoma by promoting FoxO3a and inhibiting the Nrf2/TXNRD1 signaling pathway
Neoplasma. 2023 Oct;70(5):633-644. doi: 10.4149/neo_2023_221122N1124.ABSTRACTRadiotherapy is widely used as the first-line treatment for nasopharyngeal carcinoma (NPC). However, the resistance of some patients to treatment lowers its clinical effectiveness. Compared to typical epithelial cells, NPC markedly lowers the Ras-association domain family 1A (RASSF1A) protein expression. RASSF1A overexpression sensitizes NPC cells to radiotherapy. Mechanistically, RASSF1A promotes the expression of Forkhead box O3a (FoxO3a) in the nucleus and inhibits the Nuclear factor E2-related factor 2 (Nrf2) signaling pathway via binding to t...

Desmoplasia in non-small cell lung carcinomas is associated with low programmed death-ligand 1 expression and the absence of tumor-infiltrating lymphocytes
In conclusion, to our knowledge, this is the first study that points to major differences in terms of immunological attributes between desmoplastic and non-desmoplastic areas in NSCLC. The desmoplastic component, therefore, may represent an immunologically distinct tumor area in which PD-L1 immunohistochemistry and CD8+ T cell count should be evaluated separately.PMID:38053375 | DOI:10.4149/neo_2023_221213N1178 (Source: Neoplasma)

TRIM11 regulated by m6A modification promotes the progression of cervical cancer by PHLPP1 ubiquitination
Neoplasma. 2023 Oct;70(5):659-669. doi: 10.4149/neo_2023_230104N7.ABSTRACTCervical cancer (CC) is a common cancer in women and a serious threat to women's lives. TRIM11 has been confirmed as a carcinogen in multiple cancers. Here, we will excavate the detailed mechanism of TRIM11 in CC. CC cell lines and nude mice were experimental subjects in this study. The abundance of genes and proteins was detected using qRT-PCR, western blot, and IHC. Cell proliferation, migration, and invasion were determined by CCK-8 assay, wound healing assay, and Transwell, respectively. The interactions among METTL14, TRIM11, and PHLPP1 were con...

Exploring the expression of SNHG1 and its effect on the PI3K-AKT axis in nasopharyngeal cancer
This study first analyzed the diagnostic performance and related signaling pathways of SNHG1 in NPC through bioinformatics. The expression of SNHG1 was verified by RT-qPCR, and the expression of the signaling pathway was detected using immunohistochemistry. Bioinformatics analysis results showed that SNHG1 was significantly overexpressed in head and neck squamous cell carcinoma (HNSC) and NPC tissues. RT-qPCR detection confirmed the significant overexpression of SNHG1 in NPC tissues. Enrichment analysis showed that SNHG1 may act on NPC through the PI3K-AKT signaling pathway. Immunohistochemistry experiment revealed PI3K-AK...

MCM2 promotes the stemness of endometrial cancer cells via the Akt/ β-catenin pathway
In this study, we aim to determine the biological function of MCM2 in EC cells and identify the potential underlying mechanisms. MCM2 expression and prognostic significance were analyzed in TCGA-UCEC datasets. Combining bioinformatics analyses and experiments, stemness-related molecules and phenotypes were examined to evaluate the impact of MCM2 on stemness in EC cells. The major findings of these analyses are as follows: 1) MCM2 is expressed at higher levels in EC tissues than in normal endometrial tissues. High expression of MCM2 is related to the characteristics of poorly differentiated EC. High MCM2 expression is corre...

RNASEH1-AS1 induced by H3K27ac stabilizes ANXA2 mRNA to promote the progression of colorectal cancer through recruiting BUD13
In this study, the function and mechanism of RNASEH1-AS1 in CRC were investigated. RT-qPCR and western blot detected the expression of targeted genes in tissues and cells. CCK-8, clone formation, wound healing assay, and Transwell were applied to evaluate CRC cell malignant behaviors. ChIP, RIP, and RNA pull-down validated interactions among RNASEH1-AS1, H3K27ac, CBP, BUD13, and ANXA2. Nucleoplasmic separation and FISH assay determined the location of RNASEH1-AS1 in CRC cells. IHC assay was used to detect Ki-67 expression in tumor tissues from mice. RNASEH1-AS1 was highly expressed in CRC tumor tissues and cells. RNASEH1-A...
