Aromatase inhibitors use and risk for cardiovascular disease in breast cancer patients: A population-based cohort study
CONCLUSION: Our results indicate an increased risk for ischemic heart disease and arrhythmia in patients treated for more than four years with AIs. This should be considered in the risk-benefit assessment concerning endocrine therapy.PMID:34265496 | DOI:10.1016/j.breast.2021.07.004

Activation of neuronal Ras ‐related C3 botulinum toxin substrate 1 (Rac1) improves post‐stroke recovery and axonal plasticity in mice
We propose that activation of neuronal Rac1 mediates the release of BDNF via PAK1 signaling, which further promotes axonal plasticity and alleviates astrogliosis, and eventually contributes to functional recovery after brain ischemia. Targeting neuronal Rac1 may offer a potential therapeutic target for promoting brain remapping and functional recovery after stroke. AbstractLong-term disability after stroke is common but the mechanisms of post-stroke recovery remain unclear. Cerebral Ras-related C3 botulinum toxin substrate (Rac) 1 contributes to functional recovery after ischemic stroke in mice. As Rac1 plays divergent rol...

Activation of Neuronal Ras ‐Related C3 Botulinum Toxin Substrate 1 (Rac1) Improves Post‐Stroke Recovery and Axonal Plasticity in Mice
AbstractLong ‐term disability after stroke is common but the mechanisms of post‐stroke recovery is unclear. Cerebral Ras‐related C3 botulinum toxin substrate (Rac) 1 contributes to functional recovery after ischemic stroke in mice. As Rac1 plays divergent roles in individual cell types after central neural system injury, we herein examined the specific role of neuronal Rac1 in post‐stroke recovery and axonal regeneration. Young male mice were subjected to 60‐minutes middle cerebral artery occlusion (MCAO). Inducible deletion of neuronal Rac1 by daily intraperitoneal injection of tamoxifen (2 mg/4 0 g) into Thy1...

Microglial-specific depletion of TAK1 is neuroprotective in the acute phase after ischemic stroke
AbstractTransforming growth factor- β-activated kinase 1 (TAK1) is upregulated after cerebral ischemia and contributes to an aggravation of brain injury. TAK1 acts as a key regulator of NF-ΚB and the MAP kinases JNK and p38 and modulates post-ischemic neuroinflammation and apoptosis. Microglia are the main TAK1-expressing immunocomp etent cells of the brain. However, little is known about the function and regulation of microglial TAK1 after cerebral ischemia. Tamoxifen-dependent conditional depletion of TAK1 in microglial cells was induced inCx3cr1creER-Tak1fl/fl mice. ThecreER-negativeTak1fl/fl mice and vehicle-treated ...

Cardiotoxicity of Use of Sequential Aromatase Inhibitors in Women With Breast Cancer
AbstractThe association between use of aromatase inhibitors (AIs) and cardiovascular outcomes is controversial. While some observational studies have assessed the cardiovascular safety of AIs as upfront treatments, their cardiotoxicity as sequential treatments with tamoxifen remains unknown. Thus, we conducted a population-based cohort study using data from the United Kingdom Clinical Practice Research Datalink linked to the Hospital Episode Statistics and Office for National Statistics databases. We employed a prevalent new-user design to propensity-score match, in a 1:2 ratio, patients switching from tamoxifen to AIs wit...

Cardiotoxicity of Sequential Aromatase Inhibitors Use in Women with Breast Cancer.
Abstract
The association between aromatase inhibitors and cardiovascular outcomes is controversial. While some observational studies have assessed their cardiovascular safety as up-front treatments, their cardiotoxic effects as sequential treatments with tamoxifen remains unknown. Thus, we conducted a population-based cohort study using the United Kingdom Clinical Practice Research Datalink linked to the Hospital Episode Statistics and Office for National Statistics databases. A prevalent new-user design was used to propensity score match, in a 1:2 ratio, patients switching from tamoxifen to aromatase inhibitors t...

GSE141972 TGF β-activated kinase 1-dependent microglial and macrophage responses aggravate long-term outcomes after ischemic stroke
Contributors : Yejie Shi ; Jun ChenSeries Type : Expression profiling by high throughput sequencingOrganism : Mus musculusMicroglia/macrophages (Mi/M Φ) can profoundly influence stroke outcomes by acquiring functionally dominant phenotypes (pro-inflammatory or anti-inflammatory; neurotoxic or neuroprotective). Identification of the molecular mechanisms that dictate the functional status of Mi/MΦ after brain ischemia/reperfusion may reveal novel therapeutic targets for stroke. We hypothesized that activation of TGFβ-activated kinase 1 (TAK1), a key MAP3K upstream of multiple inflammation-regulating pathways, drives Mi/M...

Aromatase Inhibitors and the Risk of Cardiovascular Outcomes in Women With Breast Cancer: A Population-Based Cohort Study.
CONCLUSIONS: In this population-based study, aromatase inhibitors were associated with increased risks of heart failure and cardiovascular mortality compared with tamoxifen. There were also trends toward increased risks, although nonsignificant, of myocardial infarction and ischemic stroke. The increased risk of cardiovascular events associated with aromatase inhibitors should be balanced with their favorable clinical benefits compared with tamoxifen.

Tamoxifen promotes white matter recovery and cognitive functions in male mice after chronic hypoperfusion
Publication date: Available online 5 October 2019Source: Neurochemistry InternationalAuthor(s): Yuxue Chen, Yeye Tian, Hao Tian, Qibo Huang, Yongkang Fang, Wei Wang, Yue Wan, Dengji Pan, Minjie XieAbstractCerebral white matter lesions (WMLs) induced by chronic cerebral hypoperfusion are one of the major components of stroke pathology and closely associated with cognitive impairment. However, the repair and related pathophysiology of white matter after brain injury remains relatively elusive and underexplored. Successful neuroregeneration is a method for the potential treatment of CNS disorders. A non-steroidal estrogen rec...

Using Dental Pulp Stem Cells for Stroke Therapy
Conclusion and Future Perspectives
Stem cell-based therapy is a promising alternative for stroke treatment. While stem cells from different sources, including induced PSC, ESC, MSC, and NSC, have been investigated, using NSC and enhancing the natural mechanisms is most appropriate for brain repair. In preclinical models of stroke, stem cell transplantation has led to positive outcomes through a variety of cellular and molecular mechanisms, many being mediated by the array of beneficial factors produced by the cells. Recent advances in cellular reprogramming have provided alternative sources of NSC to be investigated, allo...

Sex Differences in Sex Hormone Profiles and Prediction of Consciousness Recovery After Severe Traumatic Brain Injury
Conclusion: These findings indicate that TBI differentially affects the levels of sex-steroid hormones in men and women patients. Plasma levels of testosterone could be a good candidate blood marker to predict recovery from unconsciousness after sTBI for male patients.
Introduction
Traumatic brain injury (TBI) is a major cause of death and disability worldwide and is increasing in incidence (1). Patients with acute severe TBI (sTBI) often develop severe disorders of consciousness, i.e., coma, minimally conscious state or vegetative state. Although many patients may regain consciousness during the 1-month post-TBI p...
