Silencing circ_0043256 inhibited CoCl2-induced proliferation, migration, and aerobic glycolysis in gastric cancer cells.

We aimed to explore the role of circular RNA 0043256 (circ_0043256) in gastric cancer (GC) and its underlying mechanisms. The impact of circ_0043256 silencing on the proliferation, migration, apoptosis, and aerobic glycolysis of MKN-45 and AGS cells induced by CoCl2 was assessed through the utilization of CCK-8, wound healing assay, flow cytometry, and metabolic analysis. The interaction between circ_0043256 and miR-593-5p, as well as the involvement of the miR-593-5p/RRM2 axis in gastric cancer, were confirmed via luciferase assay, Western blot, and bioinformatics analysis.

Silencing GDI2 inhibits proliferation, migration and invasion of colorectal cancer through activation of p53 signaling pathway.

Objective: To investigate the effect of silencing GDP dissociation inhibitor 2 (GDI2) on colorectal cancer development and possible mechanisms based on transcriptomic analysis.

Methods: The differences in the expression levels of GDI2 in normal colorectal tissues and tumor tissues of colorectal cancer (CRC) patients were detected. The correlation of GDI2 expression levels with survival and clinical characteristics of CRC patients was analyzed.

Chemoprotective effect of boeravinone B against 1,2-dimethyl hydrazine induced colorectal cancer in rats via suppression of oxidative stress and inflammatory reaction.

Background: Colorectal cancer (CRC) has few or no symptoms and is often diagnosed at its end stage. Boeravinone B (BB) is a natural rotenoid which induces an antioxidative effect and has been used in cancer prevention. In this study, we scrutinized the chemoprotective effect of BB against 1,2dimethyl hydrazine (DMH) induced CRC in rats.

Circ_0081143 Contributes to Gastric Cancer Malignant Development and Doxorubicin Resistance by Elevating the Expression of YES1 by Targeting mziR-129-2-3p.

Background/aims: The increased mortality of gastric cancer (GC) is mainly attributed to the development of chemoresistance. Circular RNAs, as the novel type of biomarkers in GC, have attracted wide attention. The purpose of this study was to investigate the functional role of circ_0081143 in GC with doxorubicin (DR) resistance and its potential action mechanism.

Prognostic Significance of Preoperative Lymphocyte-to-C-Reactive Protein Ratio in Patients with Non-Metastatic Colorectal Cancer.

Background: The inflammatory indexes are attracting increasing attention as a prognostic predictor for colorectal cancer (CRC). However, the prognostic value of the preoperative lymphocyte-to-C-reactive protein ratio (LCR) in patients with non-metastatic CRC remains to be established.

Methods: A total of 955 patients from 2010 to 2014 at a single center were included.

Clinical study of XiangShaLiuJunZi decoction combined with S-1 as maintenance therapy for stage III or IV gastric carcinoma and colorectal carcinoma.

Introduction: S-1, a new oral fluorouracil chemotherapeutical drug, has been increasingly used in clinical maintenance after first-line chemotherapy for stage III or IV gastric carcinoma (GC) and colorectal carcinoma (CRC) for its own advantages. XiangshaLiujunzi Decoction (XSLJZD), a classic traditional Chinese medicine (TCM) formula with effects of alleviating the adverse reactions of chemotherapy and improving the quality of life of cancer patients has been gradually confirmed, with no more reports about the maintenance therapy mode of combination of chemotherapeutic drugs and TCM. We designed the study of XSLJZD combined with S-1 in the maintenance therapy of Stage III or IV GC and CRC, and hoped that this research program will go further and comprehensively evaluate its efficacy and safety.

Association of PHD3 and HIF2α gene expression with clinicopathological characteristics in human hepatocellular carcinoma.

Egl-9 family hypoxia-inducible factor (HIF)3/prolyl hydroxylase 3 (EGLN3/PHD3) serves a role in the progression and prognosis of cancer. PHD3 is able to induce apoptosis in HepG2 cells. In the present study, the protein levels of PHD3 and HIF2α were analyzed by western blot analysis and immunohistochemistry in 84 paired hepatocellular carcinoma (HCC) tissues and adjacent non-tumor liver tissues.

[Association of early diarrhea and fecal volume with anastomotic leakage after low anterior resection of rectal cancer].

Objective: To evaluate the association of early diarrhea and fecal volume with anastomotic leakage after low anterior resection (LAR) of rectal cancer.

Methods: Clinical data of 541 patients with rectal cancer undergoing LAR at The Affiliated Hospital of Guangdong Medical College between January 2007 and January 2017 were analyzed retrospectively. Early postoperative diarrhea was defined as at least one occurrence of more than 50 ml watery stool or at least four times defecation per day within 7 days after surgery.

Primary Pulmonary Paraganglioma: A Case Report and Review of Literature.

Primary pulmonary paraganglioma is a rare disease. We report a case of a 37-year old female patient with space-occupying lesions in the right lower pulmonary lobe during a routine examination without any symptoms. The patient underwent video-assisted thoracoscopic surgery (VATS) resection of the right middle lobe and dissection of hilar and mediastinal lymph nodes under general anesthesia.

Surgical resection and post-operative radiotherapy in an adult renal neuroblastoma patient with multiple bone and joint metastases: A case report.

Renal neuroblastoma is uncommon, particularly in adults, with only a few cases having been reported in studies published in the English language. The incidence is only 0.12 cases/1 million individuals in those aged >20 years.

Laparoscopic resection of primary adrenal ganglioneuroma: A case report and review of the literature.

Adrenal ganglioneuroma (AGN) is an extremely rare, benign tumor that originates from the neural crest tissue of the sympathetic nervous system. The majority of cases are detected incidentally, since the disease often lacks clear clinical manifestations or is asymptomatic. In addition, AGN is often misdiagnosed as being an adrenal adenoma or adrenal pheochromocytoma.

Small cell carcinoma of the urinary bladder: A case report and review of the literature.

Small cell carcinoma of the urinary bladder (SCBC) is a type of rare malignant tumor of the urinary tract. As it does not have specific symptoms and its epidemiological features are similar to transitional cell carcinoma of the bladder, it is often misdiagnosed. SCBC is highly aggressive, metastasizes very early and has a poor prognosis, and consequently, it has become a focus for urological surgeons and oncologists.

Effect of stable transfection with PHD3 on growth and proliferation of HepG2 cells in vitro and in vivo.

Objective: To establish a human hepatoma HepG2 cell line with stable expression of Prolyl hydroxylase domain 3 (PHD3) gene and study its effect of growth and proliferation in nude mice xenograft tumor.

Methods: Eukaryotic expression vectors of pcDNA 3.1-PHD3 was constructed.

Tumor suppressor TSLC1 inhibits growth, proliferation, invasiveness and angiogenesis in nude mice xenografted tumor of Eca109 cells.

Tumor suppressor in lung cancer 1 (TSLC1) is a novel tumor suppressor gene whose inactivation is implicated in the occurrence, invasion, metastasis and prognosis of esophageal cancer. TSLC1 was studied by comparing the tumor formation of TSLC1 transfectant and control cells in nude mice. Compared with blank group and mock group, tumor size and infiltrating range of transfected group was less, differentiation of tumor tissue was slightly better, and differences of tumor angiogenesis was worse.

Function and expression of prolyl hydroxylase 3 in cancers.

Hypoxia inducible factor (HIF) is a product of tumor cells that plays an important role in protecting tumor cells and adjusting to low oxygen tension through driving the progression and aggressiveness of tumors and changing the growth, angiogenesis, differentiation and metastasis of tumors. Prolyl hydroxylase 3 (PHD3) is a member of PHDs that are induced in hypoxia. Many studies have shown that PHD3 not only can hydroxylate HIF-1α, but also has various other biological functions.

Construction of a recombinant eukaryotic expression vector containing PHD3 gene and its expression in HepG2 cells.

Prolyl hydroxylase domain 3 (PHD3) is a hypoxia inducible factor-α (HIFα) regulator; it degrades HIFα in the presence of oxygen. Recently, there have been an increasing number of studies about the role of PHD3 in proliferation and apoptosis of cancer cells. However, most of the evidence for the role of PHD3 is observational, and little is known of the molecular mechanism.
