Senescence-related signatures predict prognosis and response to immunotherapy in colon cancer.

Background: Colorectal cancer (CRC) is one of the most common cancers. Cellular senescence plays a vital role in carcinogenesis by activating many pathways. In this study, we aimed to identify biomarkers for predicting the survival and recurrence of CRC through cellular senescence-related genes.

Synergistic action of gemcitabine and celecoxib in promoting the antitumor efficacy of anti-programmed death-1 monoclonal antibody by triggering immunogenic cell death.

Background: Emerging evidence suggests that immunogenic chemotherapy not only kills tumor cells but also improves the immune-suppressive tumor microenvironment by inducing immunogenic cell death (ICD), leading to sustained anti-tumor effects. The lack of ICD inducers explored in lung cancer necessitates investigation into new inducers for this context, therefore, this study aims to explore whether the gemcitabine (GEM) and celecoxib can activate the immunogenic chemotherapy progress in lung cancer tissue.

Methods: We assessed five chemotherapeutic agents for their ability to trigger ICD using and experiments, including western blotting (WB), flow cytometry, and tumor preventive vaccine assays.

sFlt-1/PIGF ratio positive associated with non-dipper type change in ambulatory blood pressure monitoring(ABPM) for preeclampsia development.

In order to explore relationship of ambulatory blood pressure monitoring (ABPM) and soluble fms-like tyrosine kinase-1/placental growth factor (sFlt-1/PlGF) in suspected preeclampsia(PE), suspected PE participants in 28 + 0 to 33 + 6 weeks underwent ABPM and sFlt-1/PlGF from July 2020 to July 2022 were included(N = 476) in study. ABPM parameters were compared between sFlt-1/PlGF ≥38 and <38 groups. Correlation analysis was performed between ABPM and sFlt-1/PlGF, and logistic regression was used to explore prediction value for PE in 2 weeks.

An iRGD-conjugated photothermal therapy-responsive gold nanoparticle system carrying siCDK7 induces necroptosis and immunotherapeutic responses in lung adenocarcinoma.

Although immunotherapy has improved the clinical treatment of lung adenocarcinoma (LUAD), many tumors have poor responses to immunotherapy. In this study, we confirmed that high expression of Cyclin-Dependent Kinase 7 (CDK7) promoted an immunosuppressive macrophage phenotype and macrophage infiltration in LUAD. Thus, we have developed an internalizing-RGD (iRGD)-conjugated gold nanoparticle (AuNP) system which carries siCDK7 to activate the antitumor immune response.

SNX-2112 Induces Apoptosis and Inhibits Proliferation, Invasion, and Migration of Non-Small Cell Lung Cancer by Downregulating Epithelial-Mesenchymal Transition via the Wnt/β-Catenin Signaling Pathway.

Lung cancer is the most frequent malignant tumor, and non-small cell lung cancer (NSCLC) is responsible for substantial mortality worldwide. The small molecule SNX-2112 was recently shown to critically effect the proliferation and apoptosis of tumor cells. Nevertheless, the precise mechanism by which SNX-2112 affects NSCLC remains poorly understood.

Circular RNA hsa_circ_0110389 promotes gastric cancer progression through upregulating SORT1 via sponging miR-127-5p and miR-136-5p.

Increasing studies have found that circular RNAs (circRNAs) are aberrantly expressed and play important roles in the occurrence and development of human cancers. However, the function of circRNAs on environmental carcinogen-induced gastric cancer (GC) progression remains poorly elucidated. In the present study, hsa_circ_0110389 was identified as a novel upregulated circRNA in malignant-transformed GC cells through RNA-seq, and subsequent quantitative real-time PCR verified that hsa_circ_0110389 was significantly increased in GC tissues and cells.

Chitosan-based nanoparticle co-delivery of docetaxel and curcumin ameliorates anti-tumor chemoimmunotherapy in lung cancer.

The application of traditional chemotherapy drugs for lung cancer has obvious limitations, such as toxic side effects, uncontrolled drug-release, poor bioavailability, and drug-resistance. Thus, to address the limitations of free drugs and improve treatment effects, we developed novel T7 peptide-modified nanoparticles (T7-CMCS-BAPE, CBT) based on carboxymethyl chitosan (CMCS), which is capable of targeted binding to the transferrin receptor (TfR) expressed on lung cancer cells and precisely regulating drug-release according to the pH value and reactive oxygen species (ROS) level. The results showed that the drug-loading content of docetaxel (DTX) and curcumin (CUR) was approximately 7.

Circ-HMGA2 (hsa_circ_0027446) promotes the metastasis and epithelial-mesenchymal transition of lung adenocarcinoma cells through the miR-1236-3p/ZEB1 axis.

Lung adenocarcinoma (LUAD) has high incidence and mortality rates worldwide; however, its detailed molecular pathology remains unclear. Although circRNAs have gradually been identified as molecules that are differentially expressed in tumors and play key roles in tumor progression, their role in LUAD is poorly understood. Through microarray analysis, we obtained the circRNA expression profile of LUAD and found that circ-HMGA2 (hsa_circ_0027446), a novel RNA, is highly expressed in LUAD.

Combination effect of curcumin with docetaxel on the PI3K/AKT/mTOR pathway to induce autophagy and apoptosis in esophageal squamous cell carcinoma.

Background: Docetaxel (DTX) is widely used to treat many malignant tumors but has many adverse effects. Curcumin (CUR) also has effects on a variety of tumor cells and can reduce the toxicity and side effects of chemotherapy drugs and the occurrence of drug resistance. However, the combination of CUR and DTX for treating esophageal cancer has not been reported.

Novel T7-Modified pH-Responsive Targeted Nanosystem for Co-Delivery of Docetaxel and Curcumin in the Treatment of Esophageal Cancer.

Background: Although single-drug chemotherapy is still an effective treatment for esophageal cancer, its long-term application is limited by severe side-effects, poor bioavailability, and drug-resistance. Increasing attention has been paid to nanomedicines because of their good biological safety, targeting capabilities, and high-efficiency loading of multiple drugs. Herein, we have developed a novel T7 peptide-modified pH-responsive targeting nanosystem co-loaded with docetaxel and curcumin for the treatment of esophageal cancer.

PLCD1 Suppressed Cellular Proliferation, Invasion, and Migration via Inhibition of Wnt/β-Catenin Signaling Pathway in Esophageal Squamous Cell Carcinoma.

Background: Phospholipase C delta 1 (PLCD1) has been found to be abnormally expressed in various cancers. However, the potential roles of PLCD1 in esophageal squamous cell carcinoma (ESCC) are still unknown.

Methods: Western blot and qPCR were used to explore PLCD1 expression in various ESCC cells.

KLK11 suppresses cellular proliferation via inhibition of Wnt/β-catenin signaling pathway in esophageal squamous cell carcinoma.

Studies have demonstrated that kallikrein-associated peptidase 11 (KLK11) is dysregulated in various cancers. However, the potential roles of KLK11 in esophageal squamous cell carcinoma (ESCC) are still unknown. In our study, we found that the expression of KLK11 in advanced ESCC was significantly down regulated than that in the adjacent tissues, and patients with higher KLK11 expression had markedly increased overall survival rates compared with those with lower KLK11 expression.

Babaodan inhibits cell growth by inducing autophagy through the PI3K/AKT/mTOR pathway and enhances antitumor effects of cisplatin in NSCLC cells.

Babaodan capsule (BBD), a traditional Chinese (TCM) formula, has been widely used as an alternative remedy for multiple types of malignancies, clinically. However, the underlying mechanisms behind the efficacy of BBD remain poorly understood, particularly in regard to lung cancer. Herein, we demonstrate that BBD induced autophagic death in A549 and A549DDP cells without apoptosis.

GPX3 suppresses tumor migration and invasion via the FAK/AKT pathway in esophageal squamous cell carcinoma.

Although an increasing number of findings have proven that glutathione peroxidase 3 (GPX3) is methylated and down-regulated in various cancers, the underlying mechanism of its occurrence in esophageal squamous cell carcinoma (ESCC) remains unknown. In the present study, we found that the methylation rate in advanced cancers was significantly higher than that in early stage cancers by a methylation-specific polymerase chain reaction. Furthermore, the proliferation and migration capacities of KYSE-510 cells were inhibited after up-regulating GPX3 expression by GPX3 lentivirus transfection.

NADH protect against radiation enteritis by enhancing autophagy and inhibiting inflammation through PI3K/AKT pathway.

Radiotherapy is an important method for cancer treatment but it has serious side-effects at high doses. One of the greatest challenges in radiotherapy is that radiation affects both healthy tissue and cancer tissues. For abdominal or pelvic lesions, the bowel is the most easily injured by irradiation.

MicroRNA-28 promotes cell proliferation and invasion in gastric cancer via the PTEN/PI3K/AKT signalling pathway.

Gastric cancer is the fourth most common malignant disease and second leading cause of cancer‑associated mortalities worldwide. Previous studies revealed aberrantly expressed microRNAs (miRNAs) in various types of human cancer; these miRNAs play important roles in tumourigenesis and tumour development. miRNAs present a considerable potential for novel therapeutic approaches for treating human cancer.

High expression of Fibronectin 1 suppresses apoptosis through the NF-κB pathway and is associated with migration in nasopharyngeal carcinoma.

Fibronectin 1 (FN1) is a member of the glycoprotein family located on chromosome 2q35. It has been reported that FN1 is upregulated in many tumors, and its expression is negatively related to the prognosis and survival of cancer patients. Through data analysis, we found that FN1 is upregulated in nasopharyngeal carcinoma (NPC).
