“In this research perspective, we discuss recent work from our lab describing an active role of HSPCs in AML and the potential implications.”

BUFFALO, NY- September 5, 2024 – A new research perspective was published in Oncotarget's Volume 15 on September 4, 2024, entitled, “Trained and ready - the case for an inflammatory memory for hematopoietic stem and progenitor cells in the AML niche.”

As noted in the abstract of this paper, lifelong hematopoiesis is sustained by the crosstalk between hematopoietic stem and progenitor cells (HSPCs) and specialized bone marrow niches. Acute myeloid leukemia (AML) disrupts this balance, as leukemic blasts secrete factors that remodel the bone marrow into a self-reinforcing leukemic niche. Additionally, HSPCs are key components of the innate immune system. Over the past decade, elegant studies of infection and experimental inflammation have demonstrated the generation of an adoptively transferable, innate immune memory.

In their research perspective, Ding-Wen Chen, Eric K. Wafula, and Peter Kurre from the Department of Pediatrics, Comprehensive Bone Marrow Failure Center, Division of Hematology and the Department of Biomedical and Health Informatics at the Children’s Hospital of Philadelphia, and the Perelman School of Medicine at the University of Pennsylvania, discuss recent findings from their lab on the active role of HSPCs in AML and its potential implications.

“Considering the abundant evidence for AML associated inflammation, and the involvement of healthy HSPCs discussed in our study, the question arises whether sterile cancer-associated inflammation also has long-term functional consequences.”

For many animals sleep is a social activity, but it’s usually studied as an individual process

2024-09-05
Group sleeping can impact when animals sleep, how long they sleep for, and how deeply they sleep. For example, groups of meerkats time their sleep according to “sleep traditions”; olive baboons sleep less when their group size increases; bumblebees suppress sleep in the presence of offspring; and co-sleeping mice can experience synchronized REM sleep. To fully understand both sleep and animal social structures, we need to pay more attention to the “social side” of sleep, animal behaviorists argue in an opinion paper publishing September 5 in the Cell Press journal ...

Human brain cancers fire electrical impulses – researchers reveal unexpected hybrid cell spiking the signals

2024-09-05
Researchers at Baylor College of Medicine and the Jan and Dan Duncan Neurological Research Institute at Texas Children’s Hospital have uncovered a new cell type in the human brain. The study published in Cancer Cell reveals that a third of the cells in glioma, a type of brain tumor, fire electrical impulses. Interestingly, the impulses, also called action potentials, originate from tumor cells that are part neuron and part glia, supporting the groundbreaking idea that neurons are not the only cells that can generate electric signals in the brain. The scientists also discovered ...

Pancreatic cancer: study finds most early staging inaccurate

2024-09-05
Staging of patients with early pancreatic cancer is inaccurate as much as 80% of the time, according to a new Cedars-Sinai Cancer study published in the peer-reviewed journal JAMA. The finding underscores the urgent need for advancements in diagnostic technology and staging, which could significantly alter early pancreatic cancer treatment and research. In this study, investigators looked at data from more than 48,000 patients in the National Cancer Database. Based on preoperative imaging, all of the patients in the study had either stage 1 or stage 2 pancreatic cancer. Following surgery to remove their tumors, more than 78% of stage ...

Study shows fentanyl’s role in Oregon overdose spike after policy decriminalizing drug possession

2024-09-05
PROVIDENCE, R.I. [Brown University] — When overdose rates spiked in Oregon in 2021 after the state decriminalized low-level drug possession, blame quickly turned to the new state law. But a new study by researchers at the Brown University School of Public Health implicates another factor: the introduction of fentanyl into Oregon’s unregulated drug market. “What's compelling about this analysis is that it follows the path of fentanyl across the country and offers testament to the ...

Vision impairment and the population attributable fraction of dementia in older adults

2024-09-05
About The Study: The population attributable fraction of dementia from vision impairments ranged from 4.9%-19.0%. While not proving a cause-and-effect relationship, these findings support inclusion of multiple objective measures of vision impairments, including contrast sensitivity and visual acuity, to capture the total potential impact of addressing vision impairment on dementia.  Corresponding Author: To contact the corresponding author, Jason R. Smith, ScM, email jsmit491@jhu.edu. To access the embargoed study: Visit our For The Media website at this link https://media.jamanetwork.com/ (doi:10.1001/jamaophthalmol.2024.3131) Editor’s ...

Balloon angioplasty vs medical management for intracranial artery stenosis

2024-09-05
About The Study: In patients with symptomatic intracranial atherosclerotic stenosis, balloon angioplasty plus aggressive medical management, compared with aggressive medical management alone, statistically significantly lowered the risk of a composite outcome of any stroke or death within 30 days or an ischemic stroke or revascularization of the qualifying artery after 30 days through 12 months. The findings suggest that balloon angioplasty plus aggressive medical management may be an effective treatment for symptomatic intracranial atherosclerotic stenosis, although the risk of stroke or ...

Cannabis laws and utilization of medications for the treatment of mental health disorders

2024-09-05
About The Study: This cross-sectional study of commercially insured patients suggests that there may have been meaningful heterogeneous associations between cannabis policy and state and between cannabis policy and drug class (e.g., decreases in dispensing of benzodiazepines but increases in dispensing of antidepressants and antipsychotics). This finding suggests additional clinical research is needed to understand the association between cannabis use and mental health. The results have implications for patient substance use and mental health–related outcomes.  Corresponding Author: To ...

2024-09-05
Researchers from Tokyo Medical and Dental University (TMDU) identify Mst1–FoxO1–C/EBP-ß signaling pathway that promotes heart cell survival Tokyo, Japan – Understanding the mechanisms behind cell death and survival is crucial when it comes to conditions like heart failure, which affects millions of people worldwide. Now, researchers from Japan have identified a mechanism which protects cardiac myocytes against ischemia, or a lack of blood supply. In this study published online on 25 July 2024 in Nature Communications, researchers from the Tokyo Medical and Dental ...

Shedding light on how oral bacteria can aggravate rheumatoid arthritis

Shedding light on how oral bacteria can aggravate rheumatoid arthritis
2024-09-05
Tokyo Medical and Dental University (TMDU) researchers investigate the molecular mechanisms that link periodontal disease to rheumatoid arthritis Tokyo, Japan – Periodontal disease, which affects the gums and tissues that surround the teeth, is one of the most prevalent dental conditions worldwide. Most often caused by the formation and accumulation of bacterial biofilm around the teeth, periodontal disease can ultimately lead to tooth loss if left unattended. Interestingly, the inflammatory effects of periodontal bacteria can go well beyond the mouth, leading to systemic effects. Over the past few decades, clinical studies have revealed that the periodontal ...
