We present the synthesis of a split-intein-mediated protein hydrogel. The building blocks of this hydrogel are two protein copolymers each containing a subunit of a trimeric protein that serves as a crosslinker and one half of a split intein. Mixing of the two protein copolymers triggers an intein trans-splicing reaction, yielding a polypeptide unit that self-assembles into a hydrogel. This hydrogel is highly pH- and temperature-stable, compatible with organic solvents, and easily incorporates...

A two dimensional model material of discotic zirconium phosphate was developed. The inorganic crystal with lamellar structure was synthesized by hydrothermal, reflux, and microwave-assisted methods. On exfoliation with organic molecules, layered crystals can be converted to monolayers, and nematic liquid crystal phase was formed at sufficient concentration of monolayers.

We describe a novel method to perform DNA replication via the polymerase chain reaction (PCR). Thermal convection is harnessed to continuously shuttle reagents between denaturing, annealing, and extension conditions by maintaining opposing surfaces of the reactor at constant temperature. This inherently simple design promises to make rapid PCR more accessible.
FAQs
By binding G-actin, Latrunculin A limits the pool of monomers available for incorporation into F-actin. This reduces filament assembly and the remodeling needed to reorganize cellular structure. In neuronal systems, the resulting shift in actin organization can expose relationships between cytoskeletal dynamics and changes in morphology, signaling, or communication.
Actin remodeling provides structural support for several neuronal processes, including neurite extension, dendritic spine formation, synaptic plasticity, and cell migration. Disrupting that remodeling may therefore influence multiple outcomes at once. Researchers must interpret changes as consequences of altered cytoskeletal dynamics while recognizing that the compound has broad cellular effects rather than a narrowly isolated target process.
Concentration and exposure time determine how strongly and how long actin organization is altered. Because Latrunculin A can produce broad effects, poorly controlled conditions may obscure the relationship between cytoskeletal disruption and the measured neuronal response. Careful control of both variables helps researchers distinguish temporary changes in structure or signaling from broader experimental effects.
Neurite extension, dendritic spine formation, synaptic plasticity, and cell migration provide complementary readouts of actin-dependent function. Neurite and spine analyses emphasize structural changes, whereas synaptic plasticity connects cytoskeletal organization with neuronal communication. Examining these processes helps reveal how actin dynamics contribute to both neuronal morphology and the regulation of signaling.
A supported experimental workflow is to expose neuronal cells or systems to Latrunculin A, control the compound’s concentration and exposure time, and then examine changes in actin-dependent structure or function. Measurements can focus on neurite extension, dendritic spine formation, cell migration, synaptic plasticity, or communication, depending on the biological question.
These experiments can show how reducing actin polymerization and remodeling affects neuronal structural features. Researchers may assess consequences for neurite extension or dendritic spine formation, using the resulting changes to connect cytoskeletal organization with neuronal morphology. Because the compound temporarily alters cytoskeletal dynamics, the observations can also clarify the importance of actin-dependent structural regulation.
Latrunculin A provides a way to examine how actin organization contributes to synaptic plasticity and neuronal communication. Altering actin dynamics allows researchers to relate cytoskeletal changes to changes in these functional processes, rather than studying structure alone. Interpretation requires controlled concentration and exposure time because broad cytoskeletal effects may influence several cellular functions simultaneously.
