Migrasome formation is initiated preferentially in tubular junctions by membrane tension.

Biophys J

January 2025

Department of Physiology and Pharmacology, Sackler Faculty of Medicine, Tel Aviv University, Tel Aviv, Israel; Center for Physics and Chemistry of Living Systems, Tel Aviv University, Tel Aviv, Israel. Electronic address:

Migrasomes, the vesicle-like membrane micro-structures, arise on the retraction fibers (RFs), the branched nano-tubules pulled out of cell plasma membranes during cell migration and shaped by membrane tension. Migrasomes form in two steps: a local RF bulging is followed by a protein-dependent stabilization of the emerging spherical bulge. Here we addressed theoretically and experimentally the previously unexplored mechanism of bulging of membrane tubular systems.

January 2025

Department of Obstetrics and Gynecology, Zhejiang Key Laboratory of Precise Protection and Promotion of Fertility, Zhejiang Provincial Clinical Research Center for Reproductive Health and Disease, Assisted Reproduction Unit, Sir Run Run Shaw Hospital, School of Medicine, Zhejiang University, Hangzhou, 310016, China.

The developmental competence and epigenetic progression of oocytes gradually become dysregulated with increasing maternal age. However, the mechanisms underlying age-related epigenetic regulation in oocytes remain poorly understood. Zygote arrest proteins 1 and 2 (ZAR1/2) are two maternal factors with partially redundant roles in maintaining oocyte quality, mainly known by regulating mRNA stability.

Weighted Echo State Graph Neural Networks Based on Robust and Epitaxial Film Memristors.

Adv Sci (Weinh)

January 2025

College of Physics Science & Technology, School of Life Sciences, Institute of Life Science and Green Development, Key Laboratory of Brain-Like Neuromorphic Devices and Systems of Hebei Province, Hebei University, Baoding, 071002, China.

Hardware system customized toward the demands of graph neural network learning would promote efficiency and strong temporal processing for graph-structured data. However, most amorphous/polycrystalline oxides-based memristors commonly have unstable conductance regulation due to random growth of conductive filaments. And graph neural networks based on robust and epitaxial film memristors can especially improve energy efficiency due to their high endurance and ultra-low power consumption.

Liver organoids have been increasingly adopted as a critical in vitro model to study liver development and diseases. However, the pre-vascularization of liver organoids without affecting liver parenchymal specification remains a long-lasting challenge, which is essential for their application in regenerative medicine. Here, the large-scale formation of pre-vascularized human hepatobiliary organoids (vhHBOs) is presented without affecting liver epithelial specification via a novel strategy, namely nonparenchymal cell grafting (NCG).

Upregulation of Cyclin E1 and subsequent activation of CDK2 accelerates cell cycle progression from G1 to S phase and is a common oncogenic driver in gynecological malignancies. WEE1 kinase counteracts the effects of Cyclin E1/CDK2 activation by regulating multiple cell cycle checkpoints. Here we characterized the relationship between Cyclin E1/CDK2 activation and sensitivity to the selective WEE1 inhibitor azenosertib.

Parental well-being is linked to the life chances of adult children in later life. Despite accumulated knowledge on the role of children's education on parental longevity in developed contexts, it remains unknown how children's education may influence the trajectories of parental physical well-being over the aging process, particularly in developing contexts. Using a growth curve model and four-wave data from the China Health and Retirement Longitudinal Study, this study examines the association between children's education and parental physical functioning trajectories as parents age.

Susceptibility map-weighted MRI can distinguish tremor-dominant Parkinson's disease from essential tremor.

Sci Rep

January 2025

Department of Neurology, Asan Medical Center, University of Ulsan College of Medicine, 88 Olympic-ro 43-gil, Songpa-gu, Seoul, 05505, Republic of Korea.

Distinguishing between Parkinson's disease (PD) and essential tremor (ET) can be challenging sometimes. Although positron emission tomography can confirm PD diagnosis, its application is limited by high cost and exposure to radioactive isotopes. Patients with PD exhibit loss of the dorsal nigral hyperintensity on brain magnetic resonance imaging (MRI).

Nuclear speckles are membraneless organelles that associate with active transcription sites and participate in post-transcriptional mRNA processing. During the cell cycle, nuclear speckles dissolve following phosphorylation of their protein components. Here, we identify the PP1 family as the phosphatases that counteract kinase-mediated dissolution.

Guangdong Provincial Key Laboratory of Biotechnology for Plant Development, School of Life Science, South China Normal University, Guangzhou 510631, China. Electronic address:

Recently, Torres-Romero et al. identified a novel lipid droplet (LD)-associated protein, α/β-hydrolase domain containing protein 1 (ABHD1), in algae. Structurally, ABHD1 promotes the budding and growth of LDs and, functionally, it hydrolyzes lyso-diacylglyceryl-N,N,N-trimethylhomoserine (lyso-DGTS) to generate glyceryl-N,N,N-trimethylhomoserine (GTS) and free fatty acids (FFAs).

Design and implication of a breast cancer-targeted drug delivery system utilizing the Kisspeptin/GPR54 system.

Int J Pharm

January 2025

Institute of Biochemistry and Molecular Biology, School of Life Sciences, Lanzhou University, Lanzhou, Gansu 730000, China. Electronic address:

Kisspeptins function as endogenous ligands for the G protein-coupled receptor GPR54. While the primary role of the Kisspeptin/GPR54 signaling pathway pertains to reproduction, several studies have shown that GPR54 is highly expressed in breast cancer, and we further confirmed this result that GPR54 expression is significantly upregulated in breast cancer cells. Based on this finding, we developed a liposomal drug delivery system utilizing the Kisspeptin/GPR54 system to treat breast cancer after confirming the safety of Kp-10-228.

Virus-host protein interaction is critical for successful completion of viral replication cycles. As the largest nonstructural protein (NSP) of porcine reproductive and respiratory syndrome virus (PRRSV), NSP2 plays multiple and critical roles in viral replication, antiviral immunity, cellular tropism and virulence. An interactome of this protein with host proteins would be instrumental in full understanding of these multifunctional roles.
