Adenosine-to-Inosine RNA Editing Within Corticolimbic Brain Regions Is Regulated in Response to Chronic Social Defeat Stress in Mice

Adenosine-to-Inosine RNA Editing Within Corticolimbic Brain Regions Is Regulated in Response to Chronic Social Defeat Stress in MiceAlec L. W.

Levanon3 and Alon Chen1,4*1Department of Stress Neurobiology and Neurogenetics, Max Planck Institute of Psychiatry, Munich, Germany2CytoReason, Tel-Aviv, Israel3The Mina and Everard Goodman Faculty of LifeSciences, Bar-Ilan University, Ramat-Gan, Israel4Department of Neurobiology, Weizmann Institute of Science, Rehovot, IsraelAdenosine-to-inosine (A-to-I) RNA editing is a co-/posttranscriptional modification of double-stranded RNA, catalyzed by the adenosine deaminase acting on RNA (ADAR) family of enzymes, which results in recognition of inosine as guanosine by translational and splicing machinery causing potential recoding events in amino acid sequences. A-to-I editing is prominent within brain-specific transcripts, and dysregulation of editing at several well-studied loci (e.g., Gria2, Htr2c) has been implicated in acute and chronic stress in rodents as well as neurological (e.g., Alzheimer’s) and psychopathological disorders such as schizophrenia and major depressive disorder. However, only a small fraction of recoding sites has been investigated within the brain following stress, and our understanding of the role of RNA editing in transcriptome regulation following environmental stimuli remains poorly understood. Thus, we aimed to investigate A-to-I editing at hundred...

Authors: Montazeri K, Bellmunt J Abstract Introduction: Since the approval of immune checkpoint inhibitors (ICIs), there has been continuing and significant progress in urothelial cancer (UC) treatment. However, only about one fifth of UC patients respond to ICI. Recently, erdafitinib was developed for treating locally advanced or metastatic UC (mUC) with FGFR3 or FGFR2 alterations, accounting for 15-20% of patients. Erdafitinib is the first targeted therapy ever approved for mUC.Areas covered: This review summarizes the preclinical and clinical data on erdafitinib for UC. PubMed search and relevant articles presen...

Authors: Jakubowska K, Koda M, Kisielewski W, Kańczuga-Koda L, Famulski W Abstract The presence of tumor cells in the large intestine stimulates hypoxia and local inflammatory mediators that activate numerous inflammatory cells, including a diverse lymphoid tumor cell population. The aim of the present study was to evaluate tumor-infiltrating lymphocytes (TILs) located in the invasive primary tumor, surrounding deposits of tumor cells and those present in distal metastatic cells in the liver of patients with colorectal cancer. Furthermore, the correlation of TILs with anatomical parameters was assessed. The study ...

The objective of the present study was to evaluate the beneficial effect of endorectal power Doppler/grayscale ultrasound-guided biopsy over that of mpMRI/TRUS-guided biopsy for decision-making regarding prostatectomy in males with a high risk of prostate cancer. Data regarding endorectal power Doppler/grayscale ultrasound-guided biopsies and mpMRI/TRUS-guided biopsies of 1,094 males with elevated specific prostate antigen, were included. Radical prostatectomy was performed in males aged

Authors: Li S, Ou Y, Li C, Wei W, Lei L, Zhang Q Abstract Acute spinal cord injury (SCI) has a high rate of disability and mortality. Although secondary SCI results in local tissue hypoxia and the release of inflammatory mediators, it is both controllable and reversible. Therefore, timely rehabilitation treatment is beneficial for the partial recovery of patients with SCI. The present study aimed to investigate the use of methylprednisolone combined with high-frequency electrotherapy as a method of rehabilitation treatment in rats with SCI. The rat SCI model was prepared using the modified Allen's method with the a...

Authors: Toma M, Beluşică L, Stavarachi M, Apostol P, Spandole S, Radu I, Cimponeriu D Abstract Colorectal cancer (CRC) is a disease preventable in up to 50% of the patients by lifestyle modifications. The preventive strategy for the decrease in the incidence and mortality of CRC is based on understanding the relations between the environmental and genetic factors. The most important identified risk factors for CRC are aging, personal and familial history of CRC or adenomas, hereditary colon cancer syndromes, dietary patterns, and inflammatory bowel disease. The purpose of this review is to update data referring ...

Conclusions &discussion: This paper is designed as a guideline and instruction manual to help those with less experience through particular situations in surgical burn care. Early excision and immediate coverage of the burn wounds represent nowadays the standard care for extensive burned patients. For patients with massive thermal injury, temporary coverage with allografts is essential. The use of allograft has multiple benefits because it plays both as physiologic and mechanical barriers.

Conclusions: CD200 has a great impact in diagnosing B- chronic lymphoproliferative disorders, especially when we want to determine the origin of a CD19, CD5 positive population and distinguish between CLL and MCL. CD 23 is a reliable marker in those cases, but, as we showed, CD23 might have a lower specificity than CD200 for CLL. We added CD200 in our panels in order to diagnose chronic lymphoproliferative disorders, not to replace CD 23, but to improve and save time in our diagnostic process. The high expression of CD200 in CLL and HCL could open the option for new- targeted therapy (anti-CD200). PMID: 31803290 [PubMed]
