Combining a CDK4/6 Inhibitor With Pemetrexed Inhibits Cell Proliferation and Metastasis in Human Lung Adenocarcinoma.

Background: Recent clinical trials of cyclin-dependent kinase 4/6 inhibitors (CDK4/6i) in human lung adenocarcinoma (LUAD) have not achieved satisfactory results. The disappointing results of single-drug treatments have prompted studies about synergistic therapies of CDK4/6i with other drugs. We aimed to test the anti-tumor effect of ribociclib (a CDK4/6i) combined with pemetrexed on LUAD and the potential mechanisms.

Active demethylation upregulates CD147 expression promoting non-small cell lung cancer invasion and metastasis.

Non-small cell lung cancer (NSCLC) is a fatal disease, and its metastatic process is poorly understood. Although aberrant methylation is involved in tumor progression, the mechanisms underlying dynamic DNA methylation remain to be elucidated. It is significant to study the molecular mechanism of NSCLC metastasis and identify new biomarkers for NSCLC early diagnosis.

The HIPEC group was treated with cisplatin (60 mg/m) administered with a HIPEC device on days 1 and 3 (30 mg/m each time), along with oral S-1, 40-60 mg, twice daily, for 14 days.

MicroRNA-10b regulates epithelial-mesenchymal transition by modulating KLF4/KLF11/Smads in hepatocellular carcinoma.

Background: Our previous work showed that miR-10b was overexpressed in hepatocellular carcinoma (HCC) and promoted HCC cell migration and invasion. Epithelial-mesenchymal transition (EMT) is involved in HCC metastasis. So, we suspected that miR-10b might participate in the HCC EMT.

Interferon-α adjuvant therapy decreases the recurrence of early clear cell renal cell carcinoma and improves the prognosis of Chinese patients.

The survival time of patients with early clear cell renal cell carcinoma (ccRCC) is fairly long, but 20% to 30% of patients with localized tumors experience relapse, and the effect of IFN-α on survival has not been well studied in patients with early ccRCC. In this study, 208 patients with early ccRCC were treated with surgery, and 54 of the patients received IFN-α as adjuvant therapy. The remaining 115 patients were treated with surgery but not with IFN-α therapy.

Interaction of KLF6 and Sp1 regulates basigin-2 expression mediated proliferation, invasion and metastasis in hepatocellular carcinoma.

Accumulating evidence suggests that the tumor suppressor gene Krüppel-like factor 6 (KLF6) plays important roles in both development and progression of cancer. However, the role of KLF6 in hepatocellular carcinoma (HCC) remains unclear. Cancer-related molecule basigin-2 plays an important role in HCC progression and metastasis.

Basigin-2 upregulated by receptor activator of NF-κB ligand enhances lung cancer-induced osteolytic lesions.

Background: Lung cancer bone metastasis causes poor prognosis. Basigin-2, a novel cancer-associated biomarker, is upregulated in lung cancer and has been linked with tumor progression. But little is known about the role of basigin-2 in lung cancer bone metastasis and osteolytic lesion.

CD147 overexpression promotes tumorigenicity in Chinese hamster ovary cells.

CD147 overexpresses in many epithelium-originated tumors and plays an important role in tumor migration and invasion. Most studies aim at the role of CD147 in tumor progression using tumor cell models. However, the influence of abnormal overexpression of CD147 on neoplastic transformation of normal cells is unknown.

A regulatory loop involving miR-22, Sp1, and c-Myc modulates CD147 expression in breast cancer invasion and metastasis.

Breast cancer is the most common cancer in women for which the metastatic process is still poorly understood. CD147 is upregulated in breast cancer and has been associated with tumor progression, but little is known about its regulatory mechanisms. In this study, we demonstrated that CD147 was overexpressed in breast cancer tissues and cell lines, and the high expression correlated with tumor invasion and metastasis.

Inhibition of synovitis and joint destruction by a new single domain antibody specific for cyclophilin A in two different mouse models of rheumatoid arthritis.

HAb18G (CD147), a cancer-associated biomarker and its role in cancer detection.

Aims: To evaluate HAb18G/CD147 as a cancer-associated biomarker using its monoclonal antibody HAb18.

Methods And Results: On immunohistochemical analysis of 28 tissue microarrays and pathological sections of 1117 breast tissue samples, HAb18G/CD147 was expressed in carcinoma with an overall positivity rate of 67.76%, which was significantly higher than that in sarcomas (27.

A novel antibody fragment targeting HAb18G/CD147 with cytotoxicity and decreased immunogenicity.

[(131)I]Metuximab injection (Licartin) was an efficient therapeutic anti-hepatocellular carcinoma (HCC) radioimmunological agent generated by labeling (131)I with the murine monoclonal antibody fragment HAb18-F(ab')(2) but human anti-mouse antibody (HAMA) response in some patients after administration limited its clinical use. To reduce the immunogenicity of murine antibody, we attempted to humanize HAb18 by variable domain resurfacing based on the three-dimensional structure of Fv fragment. Considering the surface accessibility of non-human like framework residues and the potential to form a molecular hydrogen bond within the context of the homology modeled Fv of HAb18, three residues in a single chain fragment of antibody variable region of HAb18 (HAb18scFv) were replaced by their human counterparts.

Regulation of matrix metalloproteinase production and tumor cell invasion by four monoclonal antibodies against different epitopes of HAb18G/CD147 extracellular domain.

HAb18G/CD147, a membrane spanning molecule and highly expressed in hepatocellular carcinoma (HCC) cells, was shown to stimulate the production of matrix metalloproteinases (MMPs) in the interaction of tumor cells and fibroblasts. Studies on the EMMPRIN/CD147 showed that CD147 extracellular domain is involved in the induction of MMPs. To study the biological molecular function of HAb18G/CD147 extracellular domain (HAb18G/CD147-ED) on production of MMPs following mediated tumor cell invasion, we isolated four novel monoclonal anibodies (MAbs)-1B3, 3B3, HAb18Gedomab1, and HAb18Gedomab2-against HAb18G/CD147-ED by immunization of BALB/c mice with purified HAb18G/CD147-ED fragments, which were efficiently expressed in Escherichia coli.
