[Combination Therapy of Bevacizumab plus Paclitaxel Was Effective for a Metastatic Choroidal Tumor Secondary to Breast Cancer in a Patient with Ocular Symptoms].

A 44-year-old woman experienced loss of vision and distorted vision in the right eye. After she visited our hospital, she was diagnosed with a right metastatic choroidal tumor. At the age of 35 years, she had undergone surgery for left breast cancer; as recurrence of the breast cancer was suspected, the patient was referred to our department.

SLC2A1/GLUT1 expression in mural nodules of intraductal papillary mucinous neoplasm of the pancreas.

In intraductal papillary mucinous neoplasms (IPMNs), the presence of a mural nodule showing a papillary or nodular proliferation of tumor cells in the dilated pancreatic duct is an indication for resection of IPMN. Solute carrier family 2, facilitated glucose transporter member 1, known as glucose transporter type 1 (SLC2A1/GLUT1) mediates cellular glucose uptake in many carcinomas and is correlated with increased F-fluorodeoxyglucose (F-FDG) uptake. We examined SLC2A1/GLUT1 expression in the mural nodules of 180 IPMN specimens to distinguish malignant/benign tumors.

Anterior gradient 2 downregulation in a subset of pancreatic ductal adenocarcinoma is a prognostic factor indicative of epithelial-mesenchymal transition.

Anterior gradient 2 (AGR2), a member of the protein disulfide isomerase family, has been implicated in various cancers including pancreatic ductal adenocarcinoma (PDAC) and is known to promote cancer progression. However, the prognostic value of AGR2 expression and the interaction with epithelial-mesenchymal transition (EMT) remain unclear. We investigated the clinical significance of AGR2 and EMT markers in PDAC patients by immunohistochemical analyses.

Increased expression of interleukin (IL)-35 and IL-17, but not IL-27, in gingival tissues with chronic periodontitis.

Background: Interleukin (IL)-35 plays an important role in immune regulation through the suppression of effector T-cell populations, including T-helper 17 (Th17) cells. Although Th17 cells and IL-17 are involved in the pathogenesis of periodontitis, the level of IL-35 in inflamed periodontal tissues is unclear. Here, IL-35, IL-17, and IL-27 production/expression in gingival crevicular fluid (GCF) and human gingival tissue were investigated.

Podoplanin expression in the cyst wall correlates with the progression of intraductal papillary mucinous neoplasm.

A thickened, enhanced cyst wall on imaging examinations is one of the "worrisome features" described in the consensus guidelines for management of intraductal papillary mucinous neoplasm of the pancreas (IPMN). Podoplanin (PDPN) expression by cancer-associated fibroblasts is known to be an indicator of poor prognosis in some types of cancer. We performed immunohistochemical staining for alpha-smooth muscle actin (α-SMA) in IPMN lesions and determined the pathological wall thickness by measuring the thinnest and thickest α-SMA-positive parts of the wall of the largest cyst in each case, and the mean of these two values was recorded as the wall thickness.

Pancreatic intraepithelial neoplasia in the background of invasive ductal carcinoma of the pancreas as a prognostic factor.

Aims: Of the recognized precursor lesions of pancreatic adenocarcinoma, pancreatic intraepithelial neoplasia (PanIN) is the most common form. However, little is known about the relationship between the grade of PanIN and prognosis for patients with invasive ductal carcinoma.

Methods And Results: In 124 patients with invasive ductal carcinoma, we examined the grade and number of PanIN lesions in all slides of resected pancreas.

Peritoneal myofibroblasts at metastatic foci promote dissemination of pancreatic cancer.

Myofibroblasts in the stroma of pancreatic cancers promote tumor proliferation, invasion and metastasis by increasing extracellular matrix and secretion of several growth factors. In contrast, the role of myofibroblasts at peritoneally disseminated sites of pancreatic cancer has not yet been determined. This study was designed to assess the role of myofibroblasts at peritoneally disseminated sites of pancreatic cancer.

Follicular pancreatitis, report of a case clinically mimicking pancreatic cancer and literature review.

We herein present a 71-year-old man who underwent pancreatoduodenectomy with the diagnosis of follicular pancreatitis. We could not completely deny malignancy by a preoperative imaging study. Endoscopic ultrasonography-guided fine needle aspiration biopsy demonstrated clusters of benign acinar cells and no proliferation of atypical lymphoid cells or rich plasma cells.

Hedgehog signaling pathway is a potential therapeutic target for gallbladder cancer.

Gallbladder cancer (GBC) is a particularly deadly type of cancer with a 5-year survival rate of only 10%. New effective therapeutic strategies are greatly needed. Recently, we have shown that Hedgehog (Hh) signaling is reactivated in various types of cancer and is a potential therapeutic target.

NOTCH4 is a potential therapeutic target for triple-negative breast cancer.

Background/aim: The prognosis for triple-negative breast cancer (TNBC) is poor. In the present study, we evaluated whether NOTCH4 receptor is a potential new therapeutic target for TNBC.

Materials And Methods: In vitro proliferation and invasiveness were evaluated in TNBC cells with or without small-interfering RNA (siRNA) for NOTCH4, and with or without NOTCH4 plasmid transfection.

Podoplanin expression in cancer-associated fibroblasts enhances tumor progression of invasive ductal carcinoma of the pancreas.

Background: Interactions between cancer cells and surrounding cancer-associated fibroblasts (CAFs) play an important role in cancer progression. Invasive ductal carcinoma (IDC) of the pancreas is characterized by abundant fibrous connective tissue called desmoplasia. Podoplanin (PDPN) is a lymphatic vessel marker (D2-40), and expression of PDPN by stromal CAFs has been reported to be a prognostic indicator in various types of cancer.

Differential ezrin and phosphorylated ezrin expression profiles between pancreatic intraepithelial neoplasia, intraductal papillary mucinous neoplasm, and invasive ductal carcinoma of the pancreas.

Intraductal papillary mucinous neoplasms (IPMNs) and pancreatic intraepithelial neoplasia (PanINs) are important premalignant lesions of pancreatic cancer. Ezrin is a member of the ezrin, radixin, and moesin protein family and acts as a cross-linker between the plasma membrane and the actin cytoskeleton. We investigated the roles of ezrin during carcinogenesis in IPMN and invasive ductal carcinoma and examined whether ezrin was a prognostic factor.

Computed tomographic lymphography predicts the difficulty of sentinel lymph node biopsy with dye.

Background: Sentinel lymph node biopsy (SLNB) has been a method of choice for treating breast cancer. Computed tomographic lymphography (CT-LG) provides a view of the sentinel lymph node (SLN) with the detailed lymphatic anatomy preoperatively, and the SLN is easily identified during SLNB. In this article, we examined the usefulness of CT-LG to predict the difficulty of SLNB with the dye method.

Selective cell affinity of biomimetic micro-nano-hybrid structured TiO2 overcomes the biological dilemma of osteoblasts.

Objective: There is a great demand for dental implant surfaces to accelerate the process of peri-implant bone generation to reduce its healing time and enable early loading. To this end, an inverse correlation between the proliferation and functional maturation (differentiation) in osteoblasts presents a challenge for the rapid generation of greater amounts of bone. For instance, osteoblasts exhibit faster differentiation but slower proliferation on micro-roughened titanium surfaces.

Enhancement of bone-titanium integration profile with UV-photofunctionalized titanium in a gap healing model.

In this study, we tested the potential of UV-photofunctionalized titanium surfaces to overcome compromised bone-titanium integration in a gap healing model. Titanium in rod and disk forms was acid etched and then stored for 4 weeks under dark ambient conditions. Titanium rods with and without UV pretreatment were placed into a rat femur with (contact healing) or without (gap healing) contact with the innate cortical bone.

Global gene expression analyses of mouse fibroblast L929 cells exposed to IC50 MMA by DNA microarray and confirmation of four detoxification genes' expression by real-time PCR.

Methyl methacrylate (MMA) is the main component of methyl methacrylic resin, which is widely used in dentistry. Previous studies have investigated whether MMA has any adverse effects on growth and gene expression in mouse fibroblast L929 cells. The present study was designed to further understand the effects of MMA by focusing on cDNA microarray data after L929 cells were exposed to MMA.
