#1
REVIEW
Dario O Fauza
Transamniotic Stem Cell Therapy, or TRASCET, is an emerging therapeutic concept for the management of congenital anomalies based on the augmentation of the biological role of select populations of stem cells that already occur in the amniotic fluid, for targeted therapeutic benefit. Amniotic fluid-derived mesenchymal stem cells (afMSCs) play a central role in the enhanced ability of the fetus to repair tissue damage. This germane recent finding constitutes the biological foundation for the use of afMSCs in TRASCET...

REVIEW
Kimihiko Banno, Mervin C Yoder
To repair and rebuild damaged tissue in diseased human subjects remains a daunting challenge for clinical medicine. Proper vascular formation that serves to deliver blood-borne nutrients and adequate levels of oxygen and remove wastes is critical for successful tissue regeneration. Endothelial colony-forming cells (ECFC) represent a promising cell source for revascularization of damaged tissue. ECFC are identified by displaying a hierarchy of clonal proliferative potential and by pronounced postnatal vascularization ability in vivo...

Pediatric patients with a neurogenic urinary bladder caused by developmental abnormalities including spina bifida exhibit chronic urological problems. Surgical management in the form of enterocystoplasty is used to enlarge the bladder but is associated with significant clinical complications. Thus, alternative methods to enterocystoplasty have been explored through the incorporation of stem cells with tissue engineering strategies. Within the context of this review, we will examine the use of bone marrow stem cells and induced pluripotent stem cells (iPSCs) as they relate to bladder regeneration at the anatomic and molecular levels...

Acute myeloid leukemia (AML) with the FLT3 internal tandem duplication (FLT3-ITD AML) accounts for 20-30% of AML cases. This subtype usually responds poorly to conventional therapies, and might become resistant to FLT3 tyrosine kinase inhibitors (TKIs) due to molecular bypass mechanisms. New therapeutic strategies focusing on resistance mechanisms are therefore urgently needed. Pim kinases are FLT3-ITD oncogenic targets that have been implicated in FLT3 TKI resistance. However, their precise biological function downstream of FLT3-ITD requires further investigation...

High-dose methotrexate (Hd-MTX) therapy has recently been applied to the treatment of adult acute lymphoblastic leukemia (ALL) based on pediatric protocols; however, its effectiveness for adult ALL has not yet been confirmed in a rigorous manner. We herein conducted a randomized phase III trial comparing Hd-MTX therapy with intermediate-dose (Id)-MTX therapy. This study was registered at UMIN-CTR (ID: C000000063). Philadelphia chromosome (Ph)-negative ALL patients aged between 25 and 64 years of age were enrolled...

BACKGROUND: IGF2 is a key determinant of fetal growth, and altered expression of IGF2 is implicated in fetal growth disorders and maternal metabolic derangements including gestational diabetes. Here we studied how increased levels of IGF2 in late pregnancy affect fetal growth. METHODS: We employed a rat model of repeated intra-fetal IGF2 administration in late pregnancy, i.e. during GD19-GD21, and measured the consequences on fetal organ weight and expression of insulin/IGF-axis components...

The importance of dopamine (DA) neurotransmission is emphasized by its direct implication in several neurological and psychiatric disorders. The DA transporter (DAT), target of psychostimulant drugs, is the key protein that regulates spatial and temporal activity of DA in the synaptic cleft via the rapid reuptake of DA into the presynaptic terminal. There is strong evidence suggesting that DAT-interacting proteins may play a role in its function and regulation. Performing a yeast-2-hybrid screening, we identified snapin, a SNARE-associated protein implicated in synaptic transmission, as a new binding partner of the carboxyl terminal of DAT...

Modeling intra-individual fluctuations in estradiol and progesterone may provide unique insight into the effects of ovarian hormones on the etiology and treatment of nicotine dependence. This randomized placebo-controlled laboratory study tested the independent and interactive effects of intra-individual ovarian hormone variation and nicotine on suppression of tobacco withdrawal symptoms and smoking behavior. Female smokers randomized to 21 mg. nicotine (TNP; n=37) or placebo (PBO; n=43) transdermal patch following overnight abstinence completed three sessions occurring during hormonally distinct menstrual cycle phases...

Although substantial progress has been made in the treatment of B-cell acute lymphoblastic leukemia (B-ALL), the prognosis of patients with either refractory or relapsed B-ALL remains dismal. Novel therapeutic strategies are needed to improve the outcome of these patients. KPT-9274 is a novel dual inhibitor of p21-activated kinase 4 (PAK4) and nicotinamide phosphoribosyltransferase (NAMPT). PAK4 is a serine/threonine kinase, which regulates a variety of fundamental cellular processes. NAMPT is a rate-limiting enzyme in the salvage biosynthesis pathway of nicotinamide adenine dinucleotide (NAD), which plays a vital role in energy metabolism...

BACKGROUND/OBJECTIVE: Dieting is a popular yet often ineffective way to lower body weight, as the majority of people regain most of their pre-dieting weights in a relatively short time. The underlying molecular mechanisms driving weight regain and the increased risk for metabolic disease are still incompletely understood. Here we investigate the molecular alterations inherited from a history of obesity. METHODS: In our model, male HFD fed obese C57BL/6J mice, were switched to a low caloric chow diet, resulting in a decline of body weight to that of lean mice...

Nuclear factor κ light chain enhancer of activated B cells (NFkB) is a transcription factor commonly associated with innate immunity, and is activated by infection and inflammation. NFkB has recently gained attention as a mediator of complex psychiatric phenomena like stress and addiction. In regards to alcohol, most research on NFkB has focused on neurotoxicity, and few studies have explored the role of NFkB in alcohol reward, reinforcement, or consumption. In these studies, we used conditioned place preference to assess the activity of NFkB in response to rewarding doses of alcohol...

BACKGROUND/OBJECTIVE: Obesity is a metabolic disorder that predisposes patients to numerous diseases and has become a major global public-health concern. Animal models of diet-induced obesity (DIO) are frequently used to study obesity, but which DIO model most accurately reflects the pathology of human obesity remains unclear. In this study, we designed a diet based on the human Western diet (WD) and compared it with the cafeteria diet (CAF) and high-fat diet (HFD) in order to evaluate which diet most closely mirrors human obesity...

Binge eating disorder (BED) is characterized by recurring episodes of excessive consumption of palatable food and an increased sensitivity to food cues. Patients with BED display an addiction-like symptomatology and the dopamine system might be a potential treatment target. The clinically safe monoamine stabilizer (-)-OSU6162 (OSU6162) restores dopaminergic dysfunction in long-term alcohol drinking rats and shows promise as a novel treatment for alcohol use disorder. Here, the effects of OSU6162 on consummatory (binge-like eating) and appetitive (cue-controlled seeking) behavior motivated by chocolate-flavored sucrose pellets were evaluated in non-food-restricted male Lister Hooded rats...

Reduced thalamic volume is consistently observed in schizophrenia, and correlates with cognitive impairment. Targeted cognitive training (TCT) of auditory processing in schizophrenia drives improvements in cognition that are believed to result from functional neuroplasticity in prefrontal and auditory cortices. In this study, we sought to determine whether response to TCT is also associated with structural neuroplastic changes in thalamic volume in patients with early schizophrenia (ESZ). Additionally, we examined baseline clinical, cognitive, and neural characteristics predictive of a positive response to TCT...
