Regulatory factor X-5/SCL/TAL1 interruption site axis promotes aerobic glycolysis and hepatocellular carcinoma cell stemness.

The incidence and development of various tumors, such as hepatocellular carcinoma (HCC), are linked to tumor stem cells. Although research has revealed how important SCL/TAL1 interruption site (STIL) is in many human tumors, the impact of STIL on HCC stem cells is poorly understood. This study aimed to examine the regulatory mechanisms and the function of STIL in the stemness of HCC tumor cells.

HSPE1 Inhibits Bladder Cancer Ferroptosis via a Glutathione-Dependent Mechanism by Suppressing GPX4.

Bladder cancer (BLCA) remains a significant health risk despite advancements in medical science that have led to reduced incidence and death rates. While the molecular regulatory mechanisms of BLCA are not yet fully understood, HSPE1, a member of the heat shock protein family, is regarded as a reliable prognostic target for BLCA. Using data from The Cancer Genome Atlas (TCGA) database, the differential expression levels of HSPE1 and its relationship to GPX4 were examined.

TFAP2A activates CTHRC1 to influence the migration of lung adenocarcinoma cells by modulating fatty acid metabolism.

Background: Tumor metastasis is the main cause of death in lung adenocarcinoma (LAC) patients. It is known that the collagen triple helix repeats containing 1 (CTHRC1) protein is implicated in tissue remodeling and is tightly linked to the carcinogenesis and metastasis of solid tumors. However, the functional role of CTHRC1 and its potential mechanisms in LAC cell metastasis have not been fully explored.

De-escalated neoadjuvant weekly nab-paclitaxel with trastuzumab and pertuzumab versus docetaxel, carboplatin, trastuzumab, and pertuzumab in patients with HER2-positive early breast cancer (HELEN-006): a multicentre, randomised, phase 3 trial.

Background: A previous phase 2 trial showed promising outcomes for patients with HER2-positive early-stage breast cancer using neoadjuvant de-escalation chemotherapy with paclitaxel, trastuzumab, and pertuzumab. We aimed to evaluate the efficacy of weekly nab-paclitaxel compared with the standard regimen of docetaxel plus carboplatin, both with trastuzumab and pertuzumab, as neoadjuvant therapies for patients with HER2-positive breast cancer.

Methods: HELEN-006 was a multicentre, randomised, phase 3 trial done at six hospitals in China.

Prediction of the Survival Status, Immunotherapy Response, and Medication of Lung Adenocarcinoma Patients Based on Hypoxia- and Apoptosis-Related Genes.

To predict patient survival prognosis, we aimed to establish a novel set of gene features associated with hypoxia and apoptosis. RNA-seq and clinical data of LUAD were sourced from The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) databases, while hypoxia and apoptosis-related genes were obtained from the Molecular Signatures Database (MsigDB). A 13-gene-prognostic model incorporating hypoxia and apoptosis genes was developed using univariate/multivariate Cox regression, Nonnegative Matrix Factorization (NMF) clustering, and LASSO regression.

Identification and validation of biomarkers related to mitochondria during ex vivo lung perfusion for lung transplants based on machine learning algorithm.

Background: Ex vivo lung perfusion (EVLP) is a critical strategy to rehabilitate marginal donor lungs, thereby increasing lung transplantation (LTx) rates. Ischemia-reperfusion (I/R) injury inevitably occurs during LTx. Exploring the common mechanisms between EVLP and I/R may unveil new treatment targets to enhance LTx outcomes.

Long non-coding RNA AC105118.1 affects glycolysis to facilitate oxaliplatin resistance in colorectal cancer cells by modulating the miR-378a-3p/KIF26B axis.

Background: Oxaliplatin is a first-line chemotherapy drug for colorectal cancer (CRC), but many patients eventually lose treatment efficacy due to acquired resistance. AC105118.1 is a long non-coding RNA with unknown biological function.

Fusobacterium nucleatum promotes PD-L1 expression in cancer cells to evade CD8 T cell killing in breast cancer.

Background: A significant percentage of cancer-related fatalities are caused by breast cancer (BC). Fusobacterium nucleatum (Fn) is a common Gram-negative anaerobic bacterium found in various inflammatory diseases, and there are also reports suggesting its involvement in cancer progression. This study discussed molecular mechanisms of Fn-induced immune escape in BC cells.

Establishment and validation of the prognostic risk model based on the anoikis-related genes in esophageal squamous cell carcinoma.

Background: Esophageal squamous cell carcinoma (ESCC) is a malignant condition in humans. Anoikis-related genes (ARGs) are crucial to cancer progression. Therefore, more studies on the relationship between ARGs and ESCC are warranted.
