Camrelizumab Combined with Apatinib for Portal Vein Tumor Thrombus in Advanced Hepatocellular Carcinoma: Two Case Reports.

Portal vein tumor thrombus (PVTT) is a common complication of primary hepatocellular carcinoma (HCC). HCC typically infiltrates intrahepatic vessels, particularly the portal vein, leading to the formation of PVTT, marking advanced-stage HCC and correlating with poor prognosis. PVTT often complicates local treatment strategies such as surgical resection and affects the efficacy of interventions.

miR-590-5p/Tiam1-mediated glucose metabolism promotes malignant evolution of pancreatic cancer by regulating SLC2A3 stability.

Background: T lymphoma invasion and metastasis 1 (Tiam1) is a tumor related gene that specifically activates Rho-like GTPases Rac1 and plays a critical role in the progression of various malignancies. Glycolysis plays an important role in cancer progression, it is crucial for supplying energy and producing metabolic end products, which can maintain the survival of tumor cells. As yet, however, the mechanism of Tiam1 in glycolysis reprogramming of pancreatic cancer (PC) remains to be clarified.

PIAS3/SOCS1-STAT3 axis responses to oxidative stress in hepatocellular cancer cells.

The participation of STAT3 and its upstream inhibitors, PIAS3 and SOCS1, in the oxidative response of hepatocellular carcinoma (HCC) cells was uncertain. Here, the expression of PIAS3 and SOCS1 in HCC tissues and cell lines was explored, and we sought to determine whether oxidative stress epigenetically regulated PIAS3 and SOCS1 expression and STAT3 activation in HCC cells. The expression of PIAS3 and SOCS1 was markedly decreased in HCC cell lines and tissues compared to normal hepatic cells and tissues.

Granulocyte colony-stimulating factor protected against brain injury in a rat cerebral hemorrhage model by modulating inflammation.

Granulocyte colony-stimulating factor (G-CSF) has been reported to exert a protective effect against secondary brain damage, but the underlying mechanisms remain unknown. We explored the ability of G-CSF to protect the brain from injury in a rat autologous blood-induced model of intracerebral hemorrhage (ICH), with a special focus on the anti-inflammation effect. An ICH was induced in 8-week-old male rats by an infusion of autologous blood, and the rats were then randomly assigned to five treatment groups: sham, ICH, and ICH+ low-dose (25 µg/kg), middle-dose (50 µg/kg), and high-dose (75 µg/kg) G-CSF.

Role of Dipeptidyl Peptidase-4 in Atherosclerotic Cardiovascular Disease in Humans and Animals with Chronic Stress.

Exposure to psychosocial stress is a risk factor for cardiovascular disease, including vascular atherosclerosis-based cardiovascular disease (ACVD). Dipeptidyl peptidase-4 (DPP-4) is a complex enzyme that acts as a membrane-anchored cell surface exopeptidase. DPP-4 is upregulated in metabolic and inflammatory cardiovascular disorders.

Exogenous pancreatic kininogenase protects against renal fibrosis in rat model of unilateral ureteral obstruction.

Tissue kallikrein has protective function against various types of injury. In this study, we investigated whether exogenous pancreatic kininogenase (PK) conferred renoprotection in a rat model of unilateral ureteral obstruction (UUO) and HO-treated HK-2 cells in vitro. SD rats were subjected to UUO surgery, then PK (7.

Astragaloside attenuates lipopolysaccharide-induced cell apoptosis in human gingiva cells via MAPK signaling pathway.

Subjects: The aim of this study was to research the antiapoptotic effect of astragaloside, the principal component of Astragalus membranaceus (Fisch) Bge, in human gingiva cells induced by lipopolysaccharide (LPS).

Methods: According to the treatment, human gingiva cells were divided into five groups, including (1) control group without drug treatment; (2) imitating group, treated with LPS (10 μg·mL ) alone; (3) low group, treated with LPS and 50 μmol·L astragaloside; (4) medium group, treated with LPS and 100 μmol·L astragaloside; and (5) high group, treated with LPS and 150 μmol·L astragaloside. Cell proliferation and apoptosis were investigated using MTT assay and flow cytometry, respectively.

Geraniol and lupeol inhibit growth and promote apoptosis in human hepatocarcinoma cells through the MAPK signaling pathway.

Objectives: Hepatocarcinoma is one of the most lethal cancers, leading to a 5-year survival rate as low as 30% due to recurrence and metastasis. The treatment of liver cancer includes surgery and medication, of which, the former is more effective. However, surgical resection is applicable in less than 40% of patients.

Long non-coding RNA activated by TGF-β expression in cancer prognosis: A meta-analysis.

Background: Recently, long non-coding RNA activated by transforming growth factor beta (TGF-β) (lncRNA ATB) was shown to be useful in cancer prognosis, however, its prognostic value in human cancer has been inconsistent. Our study aimed to explore the prognostic role of lncRNA ATB expression in cancer prognosis.

Methods: PubMed, Embase, and Cochrane Library databases were thoroughly searched to retrieve studies focusing on the prognostic role of lncRNA ATB expression in cancer, and meta-analysis was performed.

Prognostic implications of ezrin and phosphorylated ezrin expression in non-small cell lung cancer.

Background: The cytoskeletal organizer ezrin is a member of the ezrin-radixin-moesin (ERM) family and plays important roles in not only cell motility, cell adhesion, and apoptosis, but also in various cell signaling pathways. Phosphorylation at Thr-567 and Tyr-353 are key regulatory events in the transition of the dormant to active form of ezrin. This study investigated the prognostic implications of ezrin and phosphorylated ezrin (p-ezrin) expression in non-small cell lung carcinoma (NSCLC).

Correlation between HER-2/neu(erbB-2) expression level and therapeutic effect of combination treatment with HERCEPTIN and chemotherapeutic agents in gastric cancer cell lines.

Introduction: Although advanced gastric cancer has many limitations and response rate is marginal in chemotherapy. Overexpression of human epidermal growth factor receptor 2(HER-2/neu) gene and its protein are associated with increased cell division and a high rate of tumor growth and have been reported in several malignancies. Especially, approximately 30% of breast cancer patients have overexpression of HER-2/neu protein and the overexpression metastasize faster, induces resistance of the chemotherapy and down-regulate function of estrogen receptor.

Significance of NQO1 overexpression for prognostic evaluation of gastric adenocarcinoma.

NQO1 (NAD(P)H: quinone oxidoreductase, also known as DT-diaphorase) plays a prominent role in maintaining cellular homeostasis. NQO1 is abnormally elevated in many solid cancer types, including those of the adrenal gland, breast, colon, lung, ovary, and thyroid. However, little is known about the status of NQO1 in gastric adenocarcinoma (GAC).

Identification of differentially expressed genes in gastric cancer by high density cDNA microarray.

The identification of molecular markers for diagnosis, treatment, and prognosis is a significant issue in the management of patients with gastric cancer. We compared the expression profiles of 23 gastric cancers and 22 normal gastric tissues using cDNA microarrays. We divided the samples into two sets, 11 pairs as a training set and 12 unpaired gastric cancer and 11 unpaired normal gastric tissues as a test set.

Application of mesenchymal stem cells as a vehicle to deliver replication-competent adenovirus for treating malignant glioma.

Although gene therapy was regarded as a promising approach for glioma treatment, its therapeutic efficacy was often disappointing because of the lack of efficient drug delivery systems. Mesenchymal stem cells(MSCs) have been reported to have a tropism for brain tumors and thus could be used as delivery vehicles for glioma therapy. Therefore, in this study, we attempted to treat glioma by using MSCs as a vehicle for delivering replication-competent adenovirus.

Genetic analysis of liver metastatic cell lines with different metastatic potential.

Metastasis is the major feature of malignant tumors that causes 90% of cancer deaths. Our laboratory has already established liver metastatic clones with YCC-16, isolated from the blood of a gastric cancer patient and expanded in vitro culture using a repeated orthotopic implantation method, and had reported biologic behaviour of the parental YCC-16, the orthotopic primary S1L0, and S1L1, S2L2 and S3L3 liver metastatic clones. Here, using these cell lines, we screened from chromosomal abnormalities using karyotype analysis and micro-CGH matching.

Cellular adjustment of gastric cancer for hepatic metastasis in successive orthotopic implantation model.

In order to examine the mechanisms of hepatic metastasis in gastric cancer, a repeated orthotopic implantation method was used in nude mice with YCC-16, which was isolated from the blood of a gastric cancer patient. This study compared the biological and cytogenetic phenotypes of the five cell lines, the parental YCC-16, the orthotopic primary S1L0 and the 3 subsequent liver metastatic clones of S1L1, S2L2 and S3L3. E-cadherin and DAG1 gene expression levels were measured using real-time PCR.

Human papillomavirus genotyping by oligonucleotide microarray and p16 expression in uterine cervical intraepithelial neoplasm and in invasive carcinoma in Korean women.

For evaluating the diagnostic significance of p16(INK4A) over-expression in the uterine cervical intraepithelial neoplasm and in invasive carcinoma, human papillomavirus (HPV) was detected and genotyped by oligonucleotide microarray in archival tissues of 117 cervical specimens, including 47 invasive squamous cell carcinomas (SCC), 30 cases of cervical intraepithelial neoplasia (CIN), 20 adenocarcinomas, and 20 cases of non-neoplastic cervix. The expression of p16(INK4A) protein was immunohistochemically studied in these cases and in five HPV-positive and one HPV-negative cervical cancer cell lines. HPV was detected in 50% of CIN, 61.
