The processes of tumorigenesis and development are intricate, involving numerous genes and molecular pathways. Fusion genes, direct products of abnormal chromosomal rearrangements, are key factors in the formation of many types of tumors. In recent years, the advent of sequencing technology and bioinformatics has led to the discovery of more fusion genes associated with specific types of tumors.

Yet, the causal relationship between oral microbiota and OC remains undetermined. This Mendelian randomization (MR) study utilized the most recent genome-wide association study of oral microbiota from the ADDITION-PRO study (n = 610, European ancestry), along with the summary statistics for OC from the UK Biobank consortium (643 cases and 406,821 controls, European ancestry).

The present study aimed to investigate whether lncRNA ABHD11‑AS1 regulates malignant biological behavior of CRC cells. Bioinformatic analysis, reverse transcription‑quantitative PCR and hybridization revealed that ABHD11‑AS1 expression was decreased in CRC samples and associated with an unfavorable prognosis.

Methods: Patients with advanced tumors refractory to prior standard therapies were enrolled. In phase Ib, patients received LBL-007 200 mg or 400 mg and toripalimab 240 mg intravenously once every 3 weeks.
Treatment options for recurrent or metastatic (R/M) head and neck squamous cell carcinoma (HNSCC) are limited, especially for patients who progress after immune checkpoint inhibitor (ICI) therapy. This phase Ib study investigates the efficacy and safety of SCT200, an epidermal growth factor receptor (EGFR) antibody, combined with paclitaxel or docetaxel in R/M HNSCC patients who have failed both platinum-based chemotherapy and programmed cell death protein 1 (PD-1) inhibitors. This was a multicenter, open-label study enrolling patients with resistance or intolerance to platinum-based chemotherapy and PD-1 inhibitors.

Glycosylation, a key mode of protein modification in living organisms, is critical in regulating various biological functions by influencing protein folding, transportation, and localization. Changes in glycosylation patterns are a significant feature of cancer, are associated with a range of pathological activities in cancer-related processes, and serve as critical biomarkers providing new targets for cancer diagnosis and treatment. Glycoproteins like human epidermal growth factor receptor 2 (HER2) for breast cancer, alpha-fetoprotein (AFP) for liver cancer, carcinoembryonic antigen (CEA) for colon cancer, and prostate-specific antigen (PSA) for prostate cancer are all tumor biomarkers approved for clinical use.

It is a pathological hallmark of many diseases, such as diabetes, obesity, and neurodegenerative diseases. In the unique growth characteristic and varied microenvironment of cancer, high levels of stress are necessary to maintain the rapid proliferation and metastasis of tumor cells.

However, the pharmacological actions of DADS in inhibiting the growth of colorectal cancer (CRC) cells have not been clarified. Herein, we show that DADS treatment impairs the activation of the pentose phosphate pathway (PPP) to decrease PRPP (5-phosphate ribose-1-pyrophosphate) production, enhancing DNA damage and cell apoptosis, and inhibiting the growth of CRC cells.

One of the key features of cancer is energy metabolic reprogramming which is tightly related to cancer proliferation, invasion, metastasis, and chemotherapy resistance. NcRNAs are a class of RNAs having no protein-coding potential and mainly include microRNAs, lncRNAs and circRNAs. Accumulated evidence has suggested that ncRNAs play an essential role in regulating cancer metabolic reprogramming, and the altered metabolic networks mediated by ncRNAs primarily drive carcinogenesis by regulating the expression of metabolic enzymes and transporter proteins.

Multi-source functional block-wise missing data arise more commonly in medical care recently with the rapid development of big data and medical technology, hence there is an urgent need to develop efficient dimension reduction to extract important information for classification under such data. However, most existing methods for classification problems consider high-dimensional data as covariates. In the paper, we propose a novel multinomial imputed-factor Logistic regression model with multi-source functional block-wise missing data as covariates.
