Background: Application of competent cells such as mesenchymal stem cells (MSCs) for treatment of musculoskeletal disorders in equine athletes is increasingly needed. Moreover, similarities of horse and human in size, load and types of joint injuries, make horse as a good model for MSCs therapy studies. This study was designed to isolate and characterize stemness signature of equine bone marrow-derived mesenchymal stem cells (BM-MSCs). Methods: BM of three mares was aspirated and the mononuclear cells (MNCs) were isolated using density gradient...

Osteoarthritis (OA) is a degenerative joint disease characterized by cartilage degradation and inflammation. Fisetin, a polyphenol extracted from fruits and vegetables, has been reported to have anti-inflammatory effects. Our study aimed to investigate the effect of fisetin on OA both in vitro and in vivo. In vitro, chondrocytes were pretreated with fisetin alone or fisetin combined with sirtinol (an inhibitor of SIRT1) for 2h before IL-1β stimulation. Production of NO, PGE2, TNF-α and IL-6 were evaluated by the Griess reaction and ELISAs...

BACKGROUND: In a phase III study for advanced gastric cancer (AGC), the Japan Clinical Oncology Group (JCOG) 9912 trial, we previously identified the following four prognostic factors-performance status ≥1, number of metastatic sites ≥2, no prior gastrectomy, and abnormal serum alkaline phosphatase levels-and proposed a prognostic index (good risk with 0 or 1 factor, moderate risk with 2 or 3 factors, and poor risk with all 4 factors). To assess the generalizability of this index, we attempted an external validation study using an independent data set...

Studies presented here, using a murine model of bone morphogenetic protein type 2 (BMP2)-induced heterotopic ossification (HO) show that the protein initiates HO by signaling through progenitors in the endoneurium of peripheral nerves. In the mouse, these cells were identified in the endoneurium one day after BMP2 induction using antibody against phosphoSMAD (PS) 1, 5, and 8. Studies conducted in a tracking mouse that contains a tamoxifen-regulated Wnt1-Cre recombinase crossed with a td Tomato red (TR) reporter (Wnt1(CreErt) :Ai9Tm) confirmed their neural origin...

Traditional studies have shown that transcription factors, including SOX-2, OCT-4, KLF-4, Nanog and Lin-28A, contribute to the dedifferentiation and reprogramming process in normal tissues. Hypoxia is a physiological phenomenon that exists in tumors and promotes the expression of SOX-2, OCT-4, KLF-4, Nanog and Lin-28A. Therefore, an interesting question is whether hypoxia as a stimulating factor promotes the process of dedifferentiation and induces the formation of cancer stem-like cells. Studies have shown that OCT-4 and Nanog overexpression induced the formation of cancer stem cell-like cells through dedifferentiation and enhanced malignancy in lung adenocarcinoma, and reprogramming SOX-2 in pancreatic cancer cells also promoted the dedifferentiation process...

Although cancer/testis antigen DDX53 confers anti-cancer drug-resistance, the effect of DDX53 on cancer stem cell-like properties and autophagy remains unknown. MDA-MB-231 (CD133(+)) cells showed higher expression of DDX53, SOX-2, NANOG and MDR1 than MDA-MB-231 (CD133(-)). DDX53 increased in vitro self-renewal activity of MCF-7 while decreasing expression of DDX53 by siRNA lowered in vitro self-renewal activity of MDA-MB-231. DDX53 showed an interaction with EGFR and binding to the promoter sequences of EGFR...

A 63-year-old man was seen by his family doctor for epigastric distress, and he was referred to our hospital with a diagnosis of gastric cancer. Upper gastrointestinal endoscopy revealed type 3 gastric cancer(por1>tub2>tub1)at the lesser curvature of the stomach. Computed tomography suggested thickening of the wall of the stomach at the lesser curvature and bulky lymph node swelling. After a diagnosis of cT4a cN2M0, cStage III B advanced gastric cancer, we treated him with neoadjuvant chemotherapy consisting of 3 courses of SOX(oxaliplatin 100mg/m / 2 on day 1, S-1 120mg/day on day 1-14, followed by 7 days of rest)...

This report describes a patient with unresectable advanced gastric cancer who was successfully treated with potentially curative conversion surgery after chemotherapy with S-1 plus oxaliplatin(SOX). An 82-year-old man was diagnosed with type 5 gastric cancer(por1, HER2-negative)with multiple granular mucosal necroses that had metastasized throughout his body. Computed tomography revealed multiple lymph node metastases, tumor thrombosis in the splenic and portal veins, and peritoneal dissemination. After 9 courses of first-line chemotherapy with SOX, there was no tumor thrombosis in the splenic and portal veins or peritoneal dissemination, and the primary tumor and lymph node metastases were markedly reduced in size, indicative of a partial response(PR)...

A 68-year-old woman was diagnosed with advanced gastric cancer with a type 3 deep ulcer of the middle stomach by endoscopy. An abdominal computed tomography scan revealed multiple lymph node metastases and peritoneal disseminations. The clinical stage was determined to be T4a(SE), N2P1M1(PER), H0 and stage IV . A gastrectomy was scheduled after 2 courses of S-1 plus oxaliplatin(SOX)with curative intent. On day 3 after initiatingSOX therapy, the patient complained of severe abdominal pain. Because the abdominal CT scan showed intra-abdominal free air and a defect in the gastric wall, we performed an emergency total gastrectomy...

Onset of the lytic phase in the KSHV life cycle is accompanied by the rapid, global degradation of host (and viral) mRNA transcripts in a process termed host shutoff. Key to this destruction is the virally encoded alkaline exonuclease SOX. While SOX has been shown to possess an intrinsic RNase activity and a potential consensus sequence for endonucleolytic cleavage identified, the structures of the RNA substrates targeted remained unclear. Based on an analysis of three reported target transcripts, we were able to identify common structures and confirm that these are indeed degraded by SOX in vitro as well as predict the presence of such elements in the KSHV pre-microRNA transcript K12-2...

Highly tumorigenic cancer stem cells (CSCs) residing in most cancers are responsible for cancer progression and treatment failure. Zinc is an element regulator of several cell functions; however, its role in regulation of stem cell program in lung cancer has not been demonstrated. The present study reveals for the first time that zinc can suppress stem cell properties of lung cancer cells. Such findings were proved in different lung cancer cell lines (H460, H23, and H292) and it was found that CSC markers (CD133 and ALDH1A1), stem cell-associated transcription factors (Oct4, Nanog, and Sox-2), and the ability to form tumor spheroid were dramatically suppressed by zinc treatments...

Numb is a protein whose asymmetric segregation during cell division determines cell fate and has numerous functions relevant to multiple fields of study, including developmental neurobiology and cancer biology. Little is known about the role of Numb in esophageal squamous cell carcinoma (ESCC), the predominant histological esophageal carcinoma in Asian populations. In this study, we focused on the expression and biological functions of Numb in the context of ESCC. From analysis of tissue microarrays with 212 patients, it was found that Numb was significantly upregulated in ESCC tissues compared to corresponding non-cancerous tissues...

Purpose: The cellular origin of retinoblastoma is uncertain as constituent tumor cells heterogeneously express markers of both immature and mature retinal cells. An immunohistochemical analysis of cellular origin may yield valuable insights into disease progression and treatment options. This study aimed to determine the cellular origin of retinoblastoma in a large case series and correlate these findings with histopathological prognostic factors. Methods: Thirty-nine retinoblastoma cases were histopathologically diagnosed and analyzed by immunohistochemistry using monoclonal antibodies against the immature neural cell marker SRY-box containing gene 2 (SOX-2), the mature neuronal cell marker microtubule-associated protein 2 (MAP2), and the mature glial cell marker glial fibrillary acidic protein (GFAP)...
