In Vitro Live Cell Imaging Reveals Nuclear Dynamics and Role of the Cytoskeleton During Asymmetric Division of Pollen Mitosis I in Nicotiana Benthamiana

Cytoskeleton, EarlyView.
ABSTRACT Pollen is a male gametophyte of angiosperms. Following meiosis, the microspore undergoes an asymmetric division called pollen mitosis I (PMI), which produces two cells of different sizes: a large vegetative cell and a small generative cell. Polarized nuclear migration and positioning during PMI are important for successful pollen development ...

HIV-1 Gag Protein Associates with F-actin Present in Microfilaments

Virology, 1996
Several studies have provided evidence that the cellular cytoskeleton may be involved in the assembly and budding of retroviruses. In fractionation studies of HIV-1-infected CEM cells, the majority of the unprocessed Gag polyprotein cofractionated with the cellular cytoskeleton.

RNA-binding protein conserved in both microtubule- and microfilament-based RNA localization [PDF]

Genes & Development, 1998
Vg1 mRNA translocation to the vegetal cortex ofXenopus oocytes requires intact microtubules, and a 3′ UTRcis-acting element (termed VLE), which also mediates sequence-specific binding of several proteins. One protein, the 69-kD Vg1 RBP, associates Vg1 RNA to microtubules in vitro.

The role of Rho GTPases in facial morphogenesis

Developmental Dynamics, EarlyView.
The role of small GTPases, RHOA, RAC1, and CDC42 and pathway mediators is reviewed in the context of embryonic facial development. Lip fusion requires cytoskeletal remodeling during morphogenesis of the facial processes and during lip fusion. Fnm, frontonasal mass; lnp, lateral nasal process; mnp, medial nasal process; mxp, maxillary process; np, nasal

Dietary and biomarker‐guided strategies as supportive measures in the fragile X syndrome

Food Biomacromolecules, EarlyView.
Abstract The fragile X syndrome (FXS) is an inherited neurodevelopmental disorder that primarily affects males, often resulting in an IQ below 55, while about two‐thirds of females also experience intellectual disability. Physical features may include an elongated face, prominent ears, finger joint laxity, and enlarged testes in males.

Vacuolization as a Novel Approach to Cancer Therapy

Journal of Biochemical and Molecular Toxicology, Volume 40, Issue 6, June 2026.
This review discusses the novel strategy of inducing vacuole formation in cancer cells using small molecules, that induce nonapoptotic cell death mechanisms, such as paraptosis, oncosis, autophagy, and methuosis, and its potential in overcoming resistance to apoptosis‐based cancer therapies.

Identification of genetically predicted protein biomarkers and drug targets for prostate cancer via Mendelian randomization

VIEW, Volume 7, Issue 3, June 2026.
Prostate cancer, a leading cause of cancer in men globally, urgently requires improved diagnostic and treatment strategies. This study analyzed large genetic datasets and identified five key proteins (THBD, DST, IFI27L2, OSBPL10, PPP1R14A) that either increase or decrease cancer risk, while also exploring their roles in immune response and potential ...

The Chromosomal Passenger Protein Birc5b Organizes Microfilaments and Germ Plasm in the Zebrafish Embryo

PLoS Genetics, 2013
Microtubule-microfilament interactions are important for cytokinesis and subcellular localization of proteins and mRNAs. In the early zebrafish embryo, astral microtubule-microfilament interactions also facilitate a stereotypic segregation pattern of germ plasm ribonucleoparticles (GP RNPs), which is critical for their eventual selective inheritance by

Integrated proteomic and metabolomic profiling reveals sex‐stratified biomarkers predicting chronicity in paediatric primary immune thrombocytopenia

British Journal of Haematology, Volume 208, Issue 6, Page 1954-1964, June 2026.
Construction of the immune thrombocytopenia (ITP) chronicity prediction model was based on sex‐stratified multi‐omics analysis, identifying key sex‐specific predictors (intercellular adhesion molecule‐1 [ICAM‐1] and biopterin in males; actin, alpha 2, smooth muscle, aorta [ACTA‐2] and N6‐acetyl‐L‐lysine in females).

Septins in the Middle—Makers and Breakers of Membrane Contact Sites

Journal of Neurochemistry, Volume 170, Issue 6, June 2026.
Septins are a family of GTP‐binding proteins that assemble into heteromeric oligomers and polymers, associating with specific membrane domains and organelles according to their subunit composition. Growing evidence places septins at membrane contact sites (MCS) — key hubs for intracellular communication that mediate exchange of ions, lipids, and ...
