Objective: To study the regulatory effect and molecular mechanism of juglone on apoptosis of cervical cancer Hela cells.

Methods: Cervical cancer Hela cells were cultured and treated with different dosages of juglone (10, 20, and 40 μmol/L, respectively) and c-Jun N-terminal kinase (JNK) inhibitor SP600125 (10, 20, and 40 μmol/L, respectively). Then cellular proliferative activity and the expression of JNK/c-Jun pathway molecule and apoptotic molecule in the cells were detected.

Objective: To study the expression of E6 and E7 mRNA in high-risk human papillomavirus (HPV) HPV-18 and the relationship between the expression of invasive gene and cervical carcinoma.

Methods: A total of 119 patients with cervical cancer, cervical erosion and cervical HPV infection who were diagnosed in our hospital were selected and randomly divided into two groups: cervical cancer group (n = 58) and non-cancerous group (n = 61). Another 60 patients with uterine leiomyoma were selected as normal control group.

Article Synopsis
  • Lycopene has shown potential anti-angiogenic effects in both laboratory and living organism tests, confirming its ability to inhibit blood vessel formation.
  • In vivo studies in rats and mice demonstrated that high doses of lycopene completely blocked the formation of vascular endothelial cells induced by VEGF, indicating its significant role in suppressing angiogenesis.
  • The mechanisms by which lycopene exerts these effects involve reducing certain protein activities and expressions that promote cell migration and invasion, as well as impacting key signaling pathways related to VEGF receptor interactions.

Objective: To explore the clinical curative effects of preoperative neoadjuvant chemotherapy (NACT) on locally advanced cervical cancer.

Methods: A total of 62 patients of stage Ib2-IIb cervical cancer received neoadjuvant chemotherapy of paclitaxel plus cisplatin for 2 - 3 courses. The clinical curative effects were evaluated according to the changes of lesion size, intraoperative conditions and postoperative pathological reactions.

Objective: The aim of this study was to investigate simultaneous laparoscopy in endometriotic women with infertility undergoing in vitro fertilization (IVF).

Materials And Methods: Forty-seven infertile patients with endometriosis were enrolled in this retrospective study and underwent IVF cycles in a university affiliated hospital.

Results: The chemical pregnancy, clinical pregnancy and live birth rates were statistically significantly different between patients with minimal or mild stage endometriosis and patients with moderate or severe stage endometriosis, who received simultaneous laparoscopy and modified IVF with a GnRH antagonist protocol.

Dental school graduates operating on patients without having had sufficient practice in school is potentially dangerous to the patients. In order to minimize this danger, it is necessary to establish a virtual learning environment for students. In this study, we incorporated DentSim, a clinical dentistry simulator, into an e-Learning platform.

Gastrin and cholecystokinin-B receptor (CCK-B) were co-expressed in human gastric carcinoma tissues, suggesting that a functional autocrine loop, the gastrin and CCK-B receptor loop, may be presented in gastric cancer cells and play an important role in the pathogenesis and progression of gastric carcinomas. The present study was aimed at studying the effects of blocking the gastrin and CCK-B receptor loop on cell proliferation and apoptosis in gastric cancer cell line SGC-7901 cells (SGC-7901 cells). First, the expression of gastrin and CCK-B receptor mRNAs and gastrin protein in SGC-7901 cells were measured by RT-PCR and immunocytochemistry, respectively.

Objective: To explore the molecular mechanism of the development of amplyopia.

Methods: Lid suture was performed on 5 kittens at 3 weeks of age to produce monocular visual deprivation. Six kittens were used as controls without any treatment.

Laminins are glycoproteins expressed in the basement membrane of multiple epithelial tissues. Previously described purification procedures for the human laminin variants laminin-5 (LN-332) and laminin-10 (LN-511) use tissue as starting material and have multiple steps. We demonstrate a two-step laminin immunoaffinity purification method to produce consistent quantities of intact and biologically active LN-332 and LN-511 from human keratinocyte (HaCaT) and human lung carcinoma (A549) cell lines, respectively.

Disruption of the extracellular matrix by proteases is crucial for tumor invasion. Laminin-10 (Ln-10) has previously been identified as a substrate for cell migration and cell adhesion, and is present in the basal lamina (BL) of both normal prostate and prostate cancer. Here, we investigate a role for membrane type 1 matrix metalloprotease (MT1-MMP) in modifying this Ln-10-rich BL.

Objective: This study was aimed to determine the expression of HSP70, ER and PR in ovarian carcinomas and to explore the relationship between HSP70 and sex steroid receptor.

Methods: The immunohistochemical way SP was performed to estimate the expression of HSP70, ER and PR in 41 cases of ovarian carcinomas and in 11 cases of normal ovarian tissue.

Results: The positive staining rate of HSP70 was 68.

Objective: To amplify the nucleotide sequence of CG-like receptor from X anthomonas maltophilia(X maltophilia).

Methods: Using the specific primer P1 designed by Grover's reported 342 bp partial nucleotide sequence of X maltophilia CG-like receptor and random primer to PCR amplify, PCR product was cloned in the pUCm-T vector. After the recombinant plasmid was tested by restriction endonuclease digestion, the insert on the recombinant plasmid was sequenced and analyzed.

Aim: To compare the expression patterns of cholecystokinin-B (CCK-B)/gastrin receptor genes in matched human gastric carcinoma and adjacent non-neoplastic mucosa of patients with gastric cancer, inflammatory gastric mucosa from patients with gastritis, normal stomachs from 2 autopsied patients and a gastric carcinoma cell line (SGC-7901), and to explore their relationship with progression to malignancy of human gastric carcinomas.

Methods: RT-PCR and sequencing were employed to detect the mRNA expression levels of CCK-B receptor and gastrin gene in specimens from 30 patients with gastric carcinoma and healthy bordering non-cancerous mucosa, 10 gastritis patients and normal stomachs from 2 autopsied patients as well as SGC-7901. The results were semi-quantified by normalizing it to the mRNA level of beta-actin gene using Lab Image software.

The purpose of this study was to examine whether interleukin-1 beta (IL-1beta) promoter and exon 5 gene polymorphisms are markers of susceptibility or clinical manifestations in Taiwanese patients with gout. The study included 196 patients in addition to 103 unrelated healthy control subjects living in central Taiwan. From genomic DNA, polymorphisms of the gene for IL-1beta promoter and IL-1beta exon 5 were typed.

Degradation of the extracellular matrix by proteolytic enzymes is a central aspect of physiological and pathologic tissue-remodeling processes such as trophoblastic implantation, wound healing, and tumor invasion. We have hypothesized that prostate adenocarcinoma cell invasion through the normal basal lamina is attributable in part to metalloproteinase-induced cleavage of laminin-5 (Ln-5) and enhanced motility of the cancer cells. We studied the role of membrane type-1-matrix metalloproteinase (MT1-MMP) expressed on the surface of prostate tumor cells in cleaving Ln-5 and enhancing the migration of prostate tumor cells.

Antitumor monoclonal antibodies have shown clinical promise as cancer cell surface targeting agents. More tumor targeting antibodies are likely to be approved by the FDA in the next few years. However, there are two major limitations in antibody-targeted therapy: large size and nonspecific uptake of the antibody molecules by the liver and the reticuloendothelial system.
