Meningeal lymphatic CGRP signaling governs pain via cerebrospinal fluid efflux and neuroinflammation in migraine models

Journal of Clinical Investigation - Cardiology

Recently developed antimigraine therapeutics targeting calcitonin gene–related peptide (CGRP) signaling are effective, though their sites of activity remain elusive. Notably, the lymphatic vasculature is responsive to CGRP signaling, but whether meningeal lymphatic vessels (MLVs) contribute to migraine pathophysiology is unknown. Mice with lymphatic vasculature deficient in the CGRP receptor (CalcrliLEC mice) treated with nitroglycerin-mediated (NTG-mediated) chronic migraine exhibit reduced pai

Androgen aggravates aortic aneurysms via suppression of PD-1 in mice

Journal of Clinical Investigation - Cardiology

Androgen has long been recognized for its pivotal role in the sexual dimorphism of cardiovascular diseases, including aortic aneurysms (AAs), a devastating vascular disease with a higher prevalence and fatality rate in men than in women. However, the mechanism by which androgen mediates AAs is largely unknown. Here, we found that male, not female, mice developed AAs when exposed to aldosterone and high salt (Aldo-salt).

New insights into cellular processes after a stroke

Science Daily - Stroke

Strokes lead to irreversible damage to the brain and are one of the most common causes of dependency or death. As the cellular reactions to a cerebral infarction are not yet fully understood, there is a lack of possible approaches to promote the regeneration of damaged nerve tissue in the brain. A new study closes crucial gaps in our knowledge and paves the way for research into new, targeted therapeutic strategies.

New AI tool simplifies heart monitoring: Fewer leads, same accuracy

Science Daily - Heart Disease

To diagnose heart conditions including heart attacks and heart rhythm disturbances, clinicians typically rely on 12-lead electrocardiograms (ECGs) -- complex arrangements of electrodes and wires placed around the chest and limbs to detect the heart's electrical activity. But these ECGs require specialized equipment and expertise, and not all clinics have the capability to perform them.

Convergent generation of atypical prions in knockin mouse models of genetic prion disease

Journal of Clinical Investigation - Cardiology

Most cases of human prion disease arise due to spontaneous misfolding of WT or mutant prion protein, yet recapitulating this event in animal models has proven challenging. It remains unclear whether spontaneous prion generation can occur within the mouse lifespan in the absence of protein overexpression and how disease-causing mutations affect prion strain properties.

Uncontrolled hypertension: The old 'silent killer' is alive and well

Science Daily - Heart Disease

High blood pressure affects about 45% of U.S. adults. In the 1970s, only about 50% of patients were aware of their hypertension. Today, 54% are aware of their high blood pressure, 40% are actively treated and 21% are actively controlled. As such, researchers alert health care providers that the old 'silent killer' is alive and well. Healthy individuals should have a systolic blood pressure of 130 mmHg or less, and a diastolic blood pressure of 80 mmHg or less.

An attenuated lymphocytic choriomeningitis virus vector enhances tumor control in mice partly via IFN-I

Journal of Clinical Investigation - Cardiology

Viral vectors are being used for the treatment of cancer. Yet, their efficacy varies among tumors and their use poses challenges in immunosuppressed patients, underscoring the need for alternatives. We report striking antitumoral effects by a nonlytic viral vector based on attenuated lymphocytic choriomeningitis virus (r3LCMV). We show in multiple tumor models that injection of tumor-bearing mice with this vector results in improved tumor control and survival.

Aberrant activation of RAS/MAPK signaling is common in cancer, and efforts to inhibit pathway components have yielded drugs with promising clinical activities. Unfortunately, treatment-provoked adaptive resistance mechanisms inevitably develop, limiting their therapeutic potential. As a central node essential for receptor tyrosine kinase–mediated RAS activation, SHP2 has emerged as an attractive cancer target.

Liver cancer initiation requires translational activation by an oncofetal regulon involving LIN28 proteins

Journal of Clinical Investigation - Cardiology

It is unknown which posttranscriptional regulatory mechanisms are required for oncogenic competence. Here, we show that the LIN28 family of RNA-binding proteins (RBPs), which facilitate posttranscriptional RNA metabolism within ribonucleoprotein networks, is essential for the initiation of diverse oncotypes of hepatocellular carcinoma (HCC). In HCC models driven by NRASG12V/Tp53, CTNNB1/YAP/Tp53, or AKT/Tp53, mice without Lin28a and Lin28b were markedly impaired in cancer initiation.
