Oncogenic Kit mutations are found in somatic gastrointestinal (GI) stromal tumors (GISTs) and mastocytosis. A mouse model for the study of constitutive activation of Kit in oncogenesis has been produced by a knock-in strategy introducing a Kit exon 11-activating mutation into the mouse genome based on a mutation found in a case of human familial GIST syndrome. Heterozygous mutant KitV558Delta/+ mice develop symptoms of disease and eventually die from pathology in the GI tract. Patchy hyperplasia of Kit-positive cells is evident within the myenteric plexus of the entire GI tract. Neoplastic lesions indistinguishable from human GISTs were observed in the cecum of the mutant mice with high penetrance. In addition, mast cell numbers in the dorsal skin were increased. Therefore KitV558Delta/+ mice reproduce human familial GISTs, and they may be used as a model for the study of the role and mechanisms of Kit in neoplasia. Importantly, these results demonstrate that constitutive Kit signaling is critical and sufficient for induction of GIST and hyperplasia of interstitial cells of Cajal. 相似文献

To evaluate the effect of citalopram treatment on quality of life (QoL) and depression in 141 patients with chronic renal failure (CRF), QoL was measured by means of the Short Form 36 (SF-36). Patients diagnosed with depression were treated with citalopram for eight weeks and evaluated for the effect of treatment on depressive symptoms and QoL. Thirty-four of 141 patients (24.1%) had depression and treatment with citalopram decreased Beck Depression Inventory Scores and increased the emotional role limitation and the mental health subscale scores of SF-36. This study suggests that citalopram can treat depression and improve QoL in patients with CRF. 相似文献

The typing for HLA-C in transplantation was rather neglected in the past. However, several recent studies have emphasized its role in transplantation and its association with the outcome. Serological typing of HLA-C could identify only a limited number of HLA-C antigens, resulting in a number of HLA-C blanks. This was mainly due to the low expression of surface HLA-C and the small number of available specific anti-sera. Performing molecular methods has identified new HLA-C alleles and filled the blank of most serological typed antigens. In this study, we compared serological and molecular typing of HLA-C in two cohorts of healthy Saudis. Our serological typing method identified HLA-C1-7 with different frequencies, 23.5% of the alleles were not identified and thus defined as blank. Using the SSP molecular method, all samples were typed and all alleles were defined. Both methods showed that C?07 and C?06 have the highest frequency in the Saudi population. Our study emphasizes the importance of molecular methods in identifying all possible HLA-C alleles. 相似文献

c-Kit is a receptor tyrosine kinase (RTK) with a pivotal role in melanogenesis, gametogenesis, and hematopoiesis. Aberrantly
activated RTK and related downstream signaling partners were identified as key elements in the molecular pathogenesis of several
malignancies. This finding culminated in a two-class model integrating constitutive activating and maturation arrest-inducing
mutations as key elements for the pathogenesis of acute myelogenous leukemia (AML). c-Kit is expressed by myeloblasts in about
60% to 80% of patients, and the most frequently observed activating RTK mutations in AML (next to FLT3) are mutations or internal
tandem duplications in c-Kit, with an overall incidence of 17%. The identification of small-molecule tyrosine kinase inhibitors capable of blocking key
kinase switches introduced a paradigm change in the treatment of diseases like gastrointestinal stromal tumors and chronic
myelogenous leukemia. Despite encouraging preclinical data, it appears that a complex clonal disease like AML will probably
benefit from a synergistic approach of targeted drugs used (at least for now) in combination with conventional chemotherapy. 相似文献

The aim of this study is to investigate the blood pressure (BP) profile, microalbuminuria, renal functions, and relations
with remaining normal kidney size in children with unilateral functioning solitary kidney (UFSK). Sixty-six children with
UFSK were equally divided into three groups: unilateral renal agenesis (URA), unilateral atrophic kidney (UAK), and unilateral
nephrectomy (UNP). Twenty-two age-, weight-, and height-matched healthy children were considered as a control group. The serum
creatinine level and first-morning urine microalbumin and creatinine concentrations were determined by the standard methods.
Also, the BP profile was determined by ambulatory blood pressure monitoring (ABPM). We found that the serum creatinine level
was higher and creatinine clearance was lower in each patient groups compared to those of the control group (p < 0.05). Compared with the controls, each group of patients had mean office, 24-h, daytime, and night-time systolic and diastolic
BP values similar to those of the controls (p > 0.05). An inverse correlation was found between the renal size standard deviation scores (SDS) of normal kidneys and 24-h
systolic and diastolic BP load SDS in all of the patients (p < 0.05; r = −0.372, r = −0.295, respectively). The observed relationship between renal size SDS and 24-h mean arterial pressure (MAP), systolic
and diastolic BP load SDS suggests that children with UFSK should be evaluated by using ABPM for the risk of hypertension. 相似文献

Malignant infantile osteopetrosis (MIOP) is a rare hereditary disorder of osteoclast function, which can be reversed by hematopoietic stem cell transplantation (SCT). We observed a high incidence of hepatic veno-occlusive disease (VOD) in transplanted patients and explored the prevention of this complication by using defibrotide (DF) as a prophylaxis. Twenty children with MIOP were consecutively transplanted in our center between 1996 and 2005. Eleven of these patients were transplanted between 1996 and 2001 and experienced an overall incidence of VOD of 63.6% (7/11). VOD was severe in three patients and one patient succumbed to VOD-related multi-organ failure. Owing to this very high incidence of VOD, DF prophylaxis was initiated in nine patients consecutively transplanted between 2001 and 2005. In this group, only one patient (11.1%) was diagnosed with moderate VOD. We report here a very high risk in patients with MIOP to develop VOD after transplantation. Prophylactic DF was implemented in our current transplant protocol and reduced the VOD rate significantly in this high-risk population. 相似文献

Significant progress has been made in identifying genetic lesions that are causally implicated in the pathogenesis of acute myeloid leukemia (AML). These insights improve our understanding of the genetic basis of the disease, a prerequisite for the development of novel therapeutic approaches. 相似文献

Chronic peritoneal dialysis (CPD) has been utilized in the treatment of children since 1989 in Turkey. The aims of this study were to summarize our experience with CPD in children and to establish a pediatric registry data system in Turkey. Standard questionnaires were sent to all pediatric CPD centers. 514 patients treated between 1989 and 2002 in 12 pediatric centers were enrolled in the study. Reflux nephropathy was the most common (18.1%) cause of renal failure. Mean age at dialysis initiation was 10.1±4.6 years. Mean duration of dialysis was 24.1±20.5 months. Continuous ambulatory peritoneal dialysis (CAPD) was the first CPD modality for 476 (92.6%) patients, 142 of whom switched to automated peritoneal dialysis (APD) during follow-up. Currently, 47.3% of the patients are still on CPD, 15.4% were transplanted, 13.2% switched to hemodialysis, 16.7% died. The patient and technique survivals were 90% and 95% at one year and 70% and 69% at five years, respectively. The survival was significantly shorter in the youngest age group (0–24 months) compared to those in older age groups (p=0.000). We herein report the first results of the TUPEPD study providing information on demographic data and survival of pediatric CPD patients. As opposed to clear recommendations in favor of APD, there is a clear preponderance of CAPD in our pediatric CPD population. That vesicoureteral reflux (VUR) is still the leading cause of renal failure is a distressing finding. Remarkably lower survival rates and transplantation ratios are as striking and distressing as the high incidence of VUR among the causes of ESRD. We conclude that we must make a great effort to achieve better results and to change these undesirable events. 相似文献
