Article Synopsis
  • The study investigates the effectiveness of induction chemotherapy for advanced nasopharyngeal carcinoma, aiming to identify biomarkers that can predict treatment outcomes using plasma metabolomics profiles.
  • A total of 166 patients were analyzed, and machine learning techniques helped create a predictive model that showed good accuracy, indicating that changes in metabolite profiles correlate with treatment efficacy.
  • Results suggest that abnormalities in plasma lipoproteins could lead to IC resistance, and the developed prediction model holds promise for improving treatment strategies in the future.*

Plasma proteins are considered the most informative source of biomarkers for disease diagnosis and monitoring. Mass spectrometry (MS)-based proteomics has been applied to identify biomarkers in plasma, but the complexity of the plasma proteome and the extremely large dynamic range of protein abundances in plasma make the clinical application of plasma proteomics highly challenging. We designed and synthesized zeolite-based nanoparticles to deplete high-abundance plasma proteins.

Serological tests for Epstein-Barr virus (EBV) antibodies have been widely conducted for the screening of nasopharyngeal carcinoma (NPC) in endemic areas. Further risk stratification of NPC can be achieved through plasma lipoprotein and metabolic profiles. A total of 297 NPC patients and 149 EBV-positive participants are enrolled from the NCT03919552 and NCT05682703 cohorts for plasma nuclear magnetic resonance (NMR) metabolomic analysis.

Novel and accurate biomarkers are needed for early detection and progression evaluation of hepatocellular carcinoma (HCC). Protein phosphatase 1 regulatory subunit 1A (PPP1R1A) has been studied in cancer biology; however, the expression pattern and biological function of PPP1R1A in HCC are unclear. The differentially expressed genes (DEGs) in HCC were screened by The Cancer Genome Atlas (TCGA) database.

TRIP13 is a member of the large superfamily of the AAA + ATPase proteins and is associated with a variety of activities. Emerging evidence has shown that TRIP13 may serve as an oncogene. However, the function of TRIP13 in breast cancer (BC) has not yet been elucidated.

Background & Aims: Copper (Cu) is an essential trace element whose serum levels have been reported to act as an effective indicator of the efficacy of radiotherapy. However, little is known about the role of Cu in radiotherapy. In this study we aimed to determine this role and investigate the precise mechanism by which Cu or Cu-related proteins regulate the radiosensitivity of hepatocellular carcinoma (HCC).

Background: Hepatocellular carcinoma (HCC) is the third leading cause of cancer mortality worldwide. Currently, there is limited knowledge of dysregulation of cellular proliferation and apoptosis that contribute to the malignant phenotype in HCC. Copper metabolism gene MURR1 domain 10 (COMMD10) is initially identified as a suppressor gene in the pathogenesis of HCC in our observations.

Background: Irradiation has emerged as a valid tool for nasopharyngeal carcinoma (NPC) in situ treatment; however, NPC derived from tissues treated with irradiation is a main cause cancer-related death. The purpose of this study is to uncover the underlying mechanism regarding tumor growth after irradiation and provided potential therapeutic strategy.

Methods: Fibroblasts were extracted from fresh NPC tissue and normal nasopharyngeal mucosa.

Carbohydrate sulfotransferase 4 (CHST4) plays an important role in lymphocyte homing and is abnormally expressed in several cancer types; however, its precise function in tumor development and progression is unknown. Here we confirm that CHST4 is aberrantly expressed in various tumor subtypes. In particular, we found that CHST4 expression was downregulated in hepatitis B virus-related hepatocellular carcinoma (HBV-HCC) tumors compared to paired normal tissue.

Interferon-induced protein 44 (IFI44) containing a guanosine-5'-triphosphate (GTP) binding domain was reported to play a significant role in the immune response to autoimmune disease. However, its roles involved in cancers remain unclear. Here, we detected the expression of IFI44 in The Cancer Genome Atlas (TCGA) Pan-cancer and generally explored the effect of IFI44 on immune infiltration in the tumor microenvironment (TME).

Background: Spectrin repeat containing nuclear envelope family member 3 (SYNE3) encodes an essential component of the linker of the cytoskeleton and nucleoskeleton (LINC) complex, namely nesprin-3. In a tumor, invasiveness and metastasis rely on the integrity of the LINC complex, while the role of SYNE3/nesprin-3 in cancer is rarely studied.

Methods: Here, we explored the expression pattern, prognostic value, and related mechanisms of SYNE3 through both experimental and bioinformatic methods.

Nasopharyngeal carcinoma (NPC) is a major health problem in the East and Southeast Asia, and the intensity modulated radiotherapy (IMRT) is the current preferred treatment method of NPC, but radioresistance-induced residual and recurrent tumors are the main cause of treatment failure. Till now, the mechanism of radioresistance and prognostic biomarkers of NPC are still unrevealed. In this study, we collected clinical NPC samples and established radioresistant NPC-R cell lines by irradiating NPC cells with fractionation doses of γ-rays.

Background: The Copper Metabolism MURR1 (COMM) domain family has been reported to play important roles in tumorigenesis. As a prototype for the COMMD family, the expression pattern and biological function of COMMD6 in human tumours remain unknown.

Methods: COMMD6 expression in BALB/c mice and human tissues was examined using real-time PCR and immunohistochemistry.

COMMD10, a member of COMMD protein, has been proved to target p65 NF-kappaB (nuclear factor-kappaB) subunit and reduce its nuclear translocation, thereby leading to the inactivation of NF-kappaB pathway and suppression of colorectal cancer invasion and metastasis. The aim of this study is to explore its expression pattern and tissue distribution in human normal tissues and other tumor tissues and to investigate the relevant mechanism. We firstly provided the expression profile and histological distribution of COMMD10 in various BALB/c mice tissues and identified the biological distribution of COMMD10 in different kinds of human normal and tumor tissues.
