Diversity of Protists III

Diversity of Protists III

Rhizaria are a diverse group of unicellular protists characterized by their threadlike cytoplasmic extensions known as pseudopodia. These structures aid in both locomotion and feeding, giving Rhizaria an amoeboid appearance. Their amoeboid morphology once led to taxonomic confusion, but molecular phylogenetics has clarified their evolutionary placement and emphasized their shared use of pseudopodia despite divergent lineages.This clade comprises diverse lineages such as Chlorarachniophyta,...

Osmoregulation in Fishes

Osmoregulation in Fishes

When cells are placed in a hypotonic (low-salt) fluid, they can swell and burst. Meanwhile, cells in a hypertonic solution—with a higher salt concentration—can shrivel and die. How do fish cells avoid these gruesome fates in hypotonic freshwater or hypertonic seawater environments?

Multi-species Conserved Sequences

Multi-species Conserved Sequences

Next-generation sequencing technologies have created large genomic databases of a variety of animals and plants. Ever since the human genome project was completed, scientists studied the genome of primates, mammals, and other phylogenetically distant living beings. Such large-scale studies have provided new insights into the evolutionary relationship between organisms.
Although the genome of each species varies greatly from each other, a few sequences are highly conserved. Such conserved...

Multipotency and Niche of Bulge Stem Cell

Multipotency and Niche of Bulge Stem Cell

A hair follicle or HF is a small part of the skin that produces the hair shaft. Paul Gerson Unna was the first to observe a bulge in the human hair follicle's outer root sheath (ORS). The bulge is present between the sebaceous gland and the arrector pili muscle and is the niche for hair follicle stem cells (HFSCs). The bulge is also a niche for melanocyte stem cells, and their loss results in graying of hair. The HFSCs express Sox9 and Lhx2, which help them maintain stemness and prevent...

Multicompartment Models: Overview

Multicompartment Models: Overview

Multicompartment models are mathematical constructs that depict how drugs are distributed and eliminated within the body. They segment the body into several compartments, symbolizing various physiological or anatomical areas connected through drug transfer processes such as absorption, metabolism, distribution, and elimination.
These models offer a more comprehensive representation of drug behavior in the body than one-compartment models. They accommodate the complexity of drug distribution,...

Diversity of Protists IV

Diversity of Protists IV

Amoebozoa represent a diverse group of terrestrial and aquatic protists that utilize lobe-shaped pseudopodia for locomotion and feeding. This characteristic differentiates them from the Rhizaria, which possess threadlike pseudopodia. The primary classifications within Amoebozoa include gymnamoebas, entamoebas, and the plasmodial and cellular slime molds. Phylogenetic evidence indicates that Amoebozoa diverged from a lineage that ultimately gave rise to fungi and animals.Gymnamoebas and...

Area of Science:

Biogerontology
Evolutionary Biology
Genomics

Background:

Annual killifish (Nothobranchius) inhabit African ephemeral water bodies, leading to short lifespans and unique evolutionary pressures.
This lack of lifespan-related natural selection has resulted in a less efficient DNA repair system.
Nothobranchius furzeri is a common model organism for aging studies, but the genus offers broader research potential.

Purpose of the Study:

To review current and emerging research topics concerning the Nothobranchius genus.
To highlight studies on lifespan control, aging mechanisms, and related biological processes.
To explore diverse research areas beyond gerontology within this genus.

Main Methods:

Review of existing scientific literature on Nothobranchius.
Analysis of studies focusing on aging, genetics, evolution, and behavior.
Discussion of methodological challenges in Nothobranchius research.

Main Results:

Nothobranchius species exhibit unique aging characteristics influenced by their environment and genetics.
Research encompasses aging, diapause, systematics, phylogeny, sex determination, genome evolution, and behavior.
Nothobranchius furzeri is a key model, but other species offer expanded research avenues.

Conclusions:

The Nothobranchius genus presents a versatile platform for diverse biological research, extending beyond aging.
Understanding their unique biology, including diapause and genome, provides insights into fundamental life processes.
Further research is needed to address methodological challenges and fully explore the genus's potential.
