Insights on Microsatellite Characteristics, Evolution, and Function From the Social Amoeba Dictyostelium discoideum

open access: yesFrontiers in Neuroscience, 2022
Microsatellites are repetitive sequences commonly found in the genomes of higher organisms. These repetitive sequences are prone to expansion or contraction, and when microsatellite expansion occurs in the regulatory or coding regions of genes this can ...

Characterisation of Aardvark, a Dictyostelium ß-catenin. [PDF]

open access: yes, 2003
Wnt signalling is active both in development and the progression of certain disease processes, most notably cancer. Glycogen Synthase Kinase-3 (GSK-3) and ß-catenin both define the canonical Wnt pathway, where GSK-3 negatively regulates ß-catenin ...

Digital image processing of optical density wave propagation in Dictyostelium discoideum and analysis of the effects of caffeine and ammonia [PDF]

open access: yes, 1989
Waves of chemotactic movement during the early phase of aggregation in Dictyostelium discoideum were analyzed by digital image processing in a manner that immediately shows the following parameters: wave propagation velocity, period length, wave ...

Helicobacter pylori In Free‐Living Amoebae: A Potential Environmental Reservoir for Persistence and Transmission

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 5, October 2026.
Free‐living amoebae may provide an underrecognised environmental niche for Helicobacter pylori, supporting its intracellular persistence, morphological plasticity, and protection from environmental stress. These interactions could facilitate prolonged survival in aquatic and food‐associated environments and contribute to potential waterborne or ...

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

open access: yesFEBS Letters, Volume 600, Issue 17, Page 2564-2578, September 2026.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

The role of the cortical cytoskeleton [PDF]

open access: yes, 1996
We generated Dictyostelium double mutants lacking the two F-actin crosslinking proteins alpha-actinin and gelation factor by inactivating the corresponding genes via homologous recombination.

Iron metabolism and resistance to infection by invasive bacteria in the social amoeba Dictyostelium discoideum

open access: yesFrontiers in Cellular and Infection Microbiology, 2013
Dictyostelium cells are forest soil amoebae, which feed on bacteria and proliferate as solitary cells until bacteria are consumed. Starvation triggers a change in life style, forcing cells to gather into aggregates to form multicellular organisms ...

CRISPR Toolbox for Genome Editing in Dictyostelium

open access: yesFrontiers in Cell and Developmental Biology, 2021
The development of new techniques to create gene knockouts and knock-ins is essential for successful investigation of gene functions and elucidation of the causes of diseases and their associated fundamental cellular processes.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, Volume 600, Issue 17, Page 2420-2436, September 2026.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Extracellular signaling in Dictyostelium

open access: yesThe International Journal of Developmental Biology, 2019
In the last few decades, we have learned a considerable amount about how eukaryotic cells communicate with each other, and what it is the cells are telling each other. The simplicity of Dictyostelium discoideum, and the wide variety of available tools to study this organism, makes it the equivalent of a hydrogen atom for cell and developmental biology.
