While the incidence of small-cell lung cancer is low, it has a poor prognosis. Patients with extensive small-cell lung cancer account for about 70% of all cases of small-cell lung cancer, with a median overall survival duration of 8-13 months and a 5-year overall survival rate of only 1%-5%. Herein, we report small-cell lung cancer diagnosed by bronchoscopic biopsy in an adult male patient in 2011.

Background: Gastric cancer (GC) is a significant health issue globally, ranking as the fifth most common cancer with over 10,000 new cases reported annually. Long non-coding RNA (lncRNA) has emerged as a critical player in cellular functions, influencing GC's development, growth, metastasis, and prognosis. However, our understanding of lncRNA's role in the pathogenesis of GC remains limited.

Germinated flaxseed (Linum usitatissimum L.) is an essential potential food ingredient, but the major energy substances (proteins, lipids, and carbohydrates) metabolites and metabolic pathways are unknown. Comprehensive metabolomic analyses were performed using Fourier transform infrared spectroscopy and high-performance liquid chromatography mass spectrometry on flaxseed from 0 to 7 d.

Gastrointestinal stromal tumors (GISTs) are primarily characterized by activating mutations of tyrosine kinase or platelet-derived growth factor receptor alpha. Although the revolutionary therapeutic outcomes of imatinib are well known, the long-term benefits of imatinib are still unclear. The effects of BRD9, a recently identified subunit of noncanonical BAF complex (ncBAF) chromatin remodeling complexes, in GISTs are not clear.

Tumor necrosis factor-alpha (TNF-α)-induced protein 8 (TNFAIP8/TIPE) family, including TNFAIP8 (TIPE), TNFAIP8 like-protein 1 (TNFAIP8L1/TIPE1), TNFAIP8 like-protein 2 (TNFAIP8L2/TIPE2), and TNFAIP8 like-protein 3 (TNFAIP8L3/TIPE3), plays a vital role in regulating inflammatory responses, immune homeostasis, and cancer development. Over the last decade, studies have shown that TIPE2 protein is differentially expressed in diverse cells and tissues. The dysregulation of TIPE2 protein can lead to dysregulation of inflammatory responses and immune homeostasis, and change the basic characteristics of cancers.

In gastrointestinal stromal tumours (GISTs), the function of bromodomain-containing 4 (BRD4) remains underexplored. BRD4 mRNA abundance was quantified in GISTs. In the current study, we investigated the role of BRD4 in GISTs.

Expression of miR-124 in gastric adenocarcinoma cell line SGC-7901 and its effect on biological functions was investigated. Expression of miR-124 in cancer tissues and paracancerous tissues of gastric adenocarcinoma patients was detected by reverse transcription-quantitative polymerase chain reaction (RT-qPCR). RT-qPCR was used to detect the expression of miR-124 in human normal gastric epithelial cells GES-1 and gastric adenocarcinoma SGC-7901 cells.

Curcumin and its chalcone derivatives have well-known, explicit biological antitumor properties, such as instance antiproliferative and apoptotic effects via multiple molecular targets. In this study, we investigated the anticancer activity of curcumin derivative L6H4 (curcumin L6H4) on gastric cancer cells. Inhibitory effects of curcumin L6H4 on gastric cancer cells (BGC-823) were studied by the diphenyltetrazolium (MTT) assay, and cell apoptosis was detected by Annexin-V/propidium iodide (PI) staining and then analyzed by flow cytometry.

Eukaryotic translation initiation factor 3 subunit H (EIF3H) is required for the progression of several types of cancer. However, little is known about the function of EIF3H in gastric carcinoma. To address this issue, in the present study, we investigated EIF3H genetic alterations in and expression of EIF3H in gastric cancer tissue samples using cBioPortal and Oncomine databases.

Neuroinflammation has been recognized as a factor in the pathogenesis of neurodegenerative diseases. Esculentoside A (EsA), a saponin isolated from Phytolacca esculenta, has been reported to have anti-inflammatory activity. However, little research has been reported on the anti-neuroinflammatory effects of EsA.

Objective: To investigate the clinical advantage of the application of modified Roux-en-Y reconstruction after totally laparoscopic total gastrectomy.

Methods: Clinical data of 36 patients who underwent totally laparoscopic total gastrectomy with Roux-en-Y reconstruction by one medical team for gastric adenocarcinoma between January 2014 and December 2014 in the Second Hospital of Jilin University were retrospectively analyzed. Patients were divided into classic Roux-en-Y group (CRY, 16 cases) and modified Roux-en-Y group (MRY, 20 cases) according to reconstructive methods.

microRNAs (miRNAs) are small non-coding RNAs that play important role in a variety of biological processes, and aberrant expression of miRNA is always associated with tumor progression and invasion. However, the role of miR-206 in colorectal cancer (CRC) is still unclear. In this study, the expression of miR-206 in CRC tissue was compared to paired normal adjacent tissue, and results indicate that miRNA-206 levels are significantly lower in CRC tissue compared to control tissue.

Human interferon-γ (hIFN-γ) is a multifunctional protein known to possess immunoregulatory, antiviral and anticancer functions. In the present study, in order to explore the biological roles of hIFN-γ and its mechanisms of action, IFN-γ was cloned and expressed in Pichia pastoris (P. pastoris) under the control of alcohol oxidase promoter 1 (AOX1).
