How to survive mild winters: Cold acclimation, deacclimation, and reacclimation in winter wheat and barley.
Plant Physiol Biochem
January 2025
Laboratory of Plant Stress Biology and Biotechnology, Department of Plant Genetics and Crop Breeding, Czech Agrifood Research Center, Drnovská 507, 161 06, Prague 6, Ruzyně, Czech Republic.
Cold acclimation and vernalization represent the major evolutionary adaptive responses to ensure winter survival of temperate plants. Due to climate change, mild winters can paradoxically worsen plant winter survival due to cold deacclimation induced by warm periods during winter. It seems that the ability of cold reacclimation in overwintering Triticeae cereals is limited, especially in vernalized plants.

Gatekeeper or accomplice? That is the paradoxical role of the blood-brain barrier (BBB) in developing brain metastasis (BM). BM occurs when cancerous cells from primary cancer elsewhere in the body gain the ability to metastasize and invade the brain parenchyma despite the formidable defense of the BBB. These metastatic cells manipulate the BBB's components, changing them from gatekeepers of the brain to accomplices that aid in their progression into the brain tissue.

Foramen ovale plays a key role in foetal circulation, however it may remain patent after birth throughout the life. Its patency is so frequent in healthy people (27-35%), such as to be considered a variant of normal. It is at risk of complications, like paradoxical embolism by right to left shunt with stroke, migraine, temporary blindness, as well as aneurysm, thrombosis and endocarditis of the fossa ovalis.

Proc Natl Acad Sci U S A

Department of Psychology, Princeton University, Princeton, NJ 08540.
Traditional gendered arrangements-norms, roles, prejudices, and hierarchies-shape every human life. Associated harms are primarily framed as women's issues due to more severe consequences women face. Yet, gendered arrangements also shape 's relationships, career paths, and health.

Cell Rep
January 2025
MOE Key Laboratory of Biosystems Homeostasis & Protection, and Zhejiang Provincial Key Laboratory of Cancer Molecular Cell Biology, Life Sciences Institute, Zhejiang University, Hangzhou, Zhejiang 310058, China; Center for Life Sciences, Shaoxing Institute, Zhejiang University, Shaoxing, Zhejiang 321000, China; Cancer Center, Zhejiang University, Hangzhou, Zhejiang 310058, China; The Second Affiliated Hospital, Zhejiang University, Hangzhou, Zhejiang 310009, China. Electronic address:
Transforming growth factor β (TGF-β) is well known to play paradoxical roles in tumorigenesis as it has both growth-inhibitory and pro-metastatic effects. However, the underlying mechanisms of how TGF-β drives the opposing responses remain largely unknown. Here, we report that ERBB4, a member of the ERBB receptor tyrosine kinase family, specifically promotes TGF-β's metastatic response but not its anti-growth response.
