Vebreltinib for Advanced Non-Small Cell Lung Cancer Harboring c-Met Exon 14 Skipping Mutation: A Multicenter, Single-Arm, Phase II KUNPENG Study.

Purpose: The KUNPENG study aimed to evaluate the efficacy and safety of vebreltinib (also known as bozitinib, APL-101, PLB-1001, and CBT-101), a potent and highly selective inhibitor of c-mesenchymal-epithelial transition (), in patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) harboring c-Met alterations.

Methods: This multicenter, multicohort, open-label, single-arm, phase II trial enrolled patients with c-Met dysregulated, locally advanced or metastatic NSCLC from January 2020 to August 2022 across 17 centers. Cohort 1 included patients with exon 14 skipping (ex14)-mutant NSCLC who had not previously received inhibitors.

Background: The present study analyzed the relationship between clinical features and the T790M mutation in non-small cell lung cancer (NSCLC) patients resistant to epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) treatment.

Methods: NSCLC patients with resistance to first-generation EGFR-TKIs in which the disease control time was more than 6 months after initial TKI treatment were enrolled. T790M mutation analysis was performed using one of the following methods according to each manufacturer's protocols: Cobas EGFR mutation test (41/105, 39.

EZH2-mediated epigenetic suppression of EphB3 inhibits gastric cancer proliferation and metastasis by affecting E-cadherin and vimentin expression.

EphB3 is a member of the EPH family of receptors and has been found to play a role in the carcinogenesis of some human cancers. However, its expression and clinical significance in gastric cancer (GC) have not been well documented. In the present study, we detected the expression of EphB3 in GC and adjacent noncancerous tissues and explored its relationships with the clinicopathological features and prognosis of GC patients.

Long non-coding RNA LUCAT1 is associated with poor prognosis in human non-small lung cancer and regulates cell proliferation via epigenetically repressing p21 and p57 expression.

Recently, long non-coding RNAs (lncRNAs) have been recognized as playing key roles in regulating cellular processes, such as proliferation, invasion, and metastasis. These lncRNAs have been shown to be abnormally expressed in tumorigenic processes. However, the role and clinical relevance of LUCAT1 in non-small-cell lung cancer (NSCLC) remain unclear.

Prognostic value of perioperative leukocyte count in resectable gastric cancer.

Aim: To investigate the prognostic significance of perioperative leukopenia in patients with resected gastric cancer.

Methods: A total of 614 eligible gastric cancer patients who underwent curative D2 gastrectomy and adjuvant chemotherapy were enrolled in this study. The relationship between pre- and postoperative hematologic parameters and overall survival was assessed statistically, adjusted for known prognostic factors.

A novel long noncoding RNA IRAIN regulates cell proliferation in non small cell lung cancer.

Long non-coding RNAs (lncRNAs) are a novel class of RNA molecules defined as transcripts longer than 200 nucleotides that lack protein coding potential. LncRNA IRAIN has been verified that it is related to acute myeloid leukemia (AML) and breast cancer. However, there was no study to clarify whether it is involved in non-small cell lung cancer (NSCLC).

Isolated gastric recurrence from ovarian carcinoma: A case report.

Although ovarian metastasis secondary to gastric cancer (Krukenberg tumor) has been extensively described in the literature, gastric metastasis from ovarian carcinoma is rare. The present case report describes a patient with gastric metastasis from ovarian carcinoma. A 51-year-old female with previously treated ovarian carcinoma of stage III according to the International Federation of Gynecology and Obstetrics was admitted to the Department of Oncology, First Affiliated Hospital of Nanjing Medical University (Nanjing, China) with high serum carbohydrate antigen-125 levels.

Decreased expression of long noncoding RNA MEG3 affects cell proliferation and predicts a poor prognosis in patients with colorectal cancer.

Colorectal cancer (CRC) remains an important public health problem in the world. Long noncoding RNA (lncRNA) is an RNA molecular that is longer than 200 nucleotides and cannot be translated into a protein. Recent studies have shown that lncRNAs play important roles in carcinogenesis and cancer metastasis.

MiR-1 targets PIK3CA and inhibits tumorigenic properties of A549 cells.

MicroRNAs are small endogenous RNAs that play important roles in the pathogenesis of human diseases, including malignancy. MicroRNA-1 (miR-1) is downregulated in non-small cell lung cancer (NSCLC); however, the underlying mechanisms by which it suppresses tumorigenesis in NSCLC are largely unknown. We investigated whether phosphoinositide-3-kinase catalytic subunit alpha (PIK3CA) was a novel target of miR-1 in the NSCLC cell line A549, and the mechanism of miR-1 inhibition of the tumorigenic properties of A549 cells is discussed.

[Correlation between expression of forkhead box M1 (FOXM1) and clinicopathological features and prognosis in patients with non-small cell lung cancer (NSCLC)].

Objective: To investigate the expression of forkhead box M1 (FOXM1) and its correlation with clinicopathological features and prognosis in patients with non-small cell lung cancer (NSCLC).

Methods: The expression of FOXM1 in 68 cases of NSCLC was detected by immunohistochemistry. The FOXM1 expression in 6 tumor tissues (3 cases with negative and 3 cases with positive expression of FOXM1) was analyzed by Western blotting to confirm the immunohistochemical results.

[Down-regulation of mTOR activity and survivin expression during tamoxifen-induced apoptosis in hepatoblastoma cells].

Objective: The aim of this study was to investigate the changes in mTOR activity and survivin expression in liver cancer cell line HepG2 cells treated with tamoxifen.

Methods: Survivin transcription level and p70S6K was demonstrated by PCR, dual-luciferase reporter assay and Western blot analysis, respectively, and the apoptosis in the HepG2 cells was detected by flow cytometry.

Results: Tamoxifen leads to apoptosis of the cells and reduction in survivin expression, as well as a dramatic reduction in the activated form of p70S6K.

The effect of endostatin and gemcitabine combined with HIFU on the animal xenograft model of human pancreatic cancer.

Objective: To investigate the influence of the recombinant human endostatin and gemcitabine combined with HIFU on the mouse xenograft model of pancreatic cancer.

Methods: Use human pancreatic cancer cell line PANC-1 to set up the mouse xenograft model, then randomized into four arms. Each arm was treated with gemcitabine, endostatin, gemcitabine combined with endostatin and normal saline respectively.

[Insulin/PI3K signalling pathway regulates the expression of survivin in liver cancer HepG2 cells].

Objective: To determine the expression level changes of survivin, a inhibitor of apoptosis protein, followed by activation of insulin receptors in human hepatocellular carcinoma HepG2 cell line, and to investigate the signalling pathway involved in the regulation.

Methods: Human hepatocellular carcinoma HepG2 cells were treated with insulin alone or pre-treated with LY294002, a specific inhibitor of PI3K signalling pathway, to determine whether blocking PI3K signaling can attenuate the up-regulation of survivin expression. Real time RT-PCR and Western blot analysis were used to measure survivin mRNA and protein changes before and after treatment, respectively.
