Article Abstract
Accumulating studies have demonstrated that non-coding RNAs (ncRNAs), including small non-coding RNAs (small ncRNAs) and long non-coding RNAs (lncRNAs), are involved in tumor growth in lung cancer (LC). However, the specific role of DGCR5 in LC progression is not yet clear. In the present study, we found that DGCR5 was downregulated and miR-1180 was upregulated in the sera and tissues of LC patients and was correlated with poor prognosis. We also found that DGCR5 suppressed proliferation, migration and invasion of LC cell lines H520 and H1299. In addition, a luciferase reporter gene assay was used to investigate the regulatory relationship between DGCR5 and miR-1180. Furthermore, we suggested that DGCR5 inhibited the expression of AKT, GSK-3β, and β-catenin by targeting miR-1180. Based on these findings, DGCR5 might serve as a potential target for the development of effective anti-neoplastic therapies in lung cancer.

Unlabelled: Leptomeningeal metastasis (LM) is a severe complication of solid malignancies, including lung adenocarcinoma, characterized by poor prognosis and diagnostic challenges. This study assesses whether curvilinear peri-brainstem hyperintense signals on MRI are a characteristic feature of LM in lung adenocarcinoma patients.
Methods: This retrospective study analyzed data from multiple centers, encompassing lung adenocarcinoma patients with peri-brainstem curvilinear hyperintense signals on MRI between January 2016 and March 2022.

Unlabelled: Encephalitis is a potentially life-threatening condition with infectious or autoimmune aetiologies. Autoimmune encephalitis includes paraneoplastic variants associated with specific onconeural antibodies such as anti-Hu, frequently linked to malignancies. Herpes simplex virus type 1 (HSV-1) is the leading infectious cause in adults.

Triple-negative breast cancer (TNBC) is the most aggressive breast cancer subtype, characterized by a high propensity for metastasis, poor prognosis, and limited treatment options. Research has demonstrated a substantial correlation between the expression of protein arginine N-methyltransferase 1 (PRMT1) and enhanced proliferation, metastasis, and poor outcomes in TNBC. However, the specific role of PRMT1 in lung metastasis and chemoresistance remains unclear.

Background: People living with HIV(PLWH) are a high-risk population for cancer. We conducted a pioneering study on the gut microbiota of PLWH with various types of cancer, revealing key microbiota.
Methods: We collected stool samples from 54 PLWH who have cancer (PLWH-C), including Kaposi's sarcoma (KS, n=7), lymphoma (L, n=22), lung cancer (LC, n=12), and colorectal cancer (CRC, n=13), 55 PLWH who do not have cancer (PLWH-NC), and 49 people living without HIV (Ctrl).

Neutrophil extracellular traps (NETs) are DNA-protein structures released during a form of programmed neutrophil death known as NETosis. While NETs have been implicated in both tumor inhibition and promotion, their functional role in cancer remains ambiguous. In this study, we compared the NET-forming capacity and functional effects of NETs derived from lung cancer (LC) patients and healthy donors (H).
