Summary
Comparing distantly related animal body plans is challenging due to their diverse shapes. Molecular regulation during embryogenesis reveals hidden evolutionary origins of body parts.
Area of Science:
- Developmental biology
- Evolutionary developmental biology
- Comparative anatomy
Background:
- Animals exhibit vast diversity in body plans and shapes, complicating the identification of homologous structures.
- Visual comparison of external morphology is insufficient to determine shared evolutionary origins between distantly related species.
Purpose of the Study:
- To investigate the molecular mechanisms underlying embryonic development to uncover conserved developmental pathways.
- To identify shared evolutionary origins of body parts that are not apparent through morphological analysis.
Main Methods:
- Comparative analysis of gene expression patterns during embryogenesis in distantly related animal taxa.
- Utilizing molecular markers to trace the developmental trajectories of homologous structures.
Main Results:
- Molecular data reveals conserved developmental processes underlying seemingly disparate body parts.
- Identified specific genes and regulatory networks involved in the formation of homologous structures across diverse animal groups.
Conclusions:
- Molecular regulation of embryogenesis provides a powerful tool for understanding deep evolutionary relationships.
- Conserved developmental pathways offer insights into the evolution of animal body plan diversity.

Loss of Tumor Suppressor Gene Functions
6.1K
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...

Muscles that Move the Head
6.0K
The muscles that move the head are a dynamic and complex group of structures that work together to facilitate a wide range of head movements, including rotation, flexion, extension, and lateral bending.
The bilateral sternocleidomastoid, or SCM, and the suprahyoid and infrahyoid muscles are significant head flexors. The SCM muscles originate at the sternum and clavicle and attach to the mastoid process of the temporal bone. The SCM contracts bilaterally to bend the head forward, whereas...

Gene Conversion
10.7K
Other than maintaining genome stability via DNA repair, homologous recombination plays an important role in diversifying the genome. In fact, the recombination of sequences forms the molecular basis of genomic evolution. Random and non-random permutations of genomic sequences create a library of new amalgamated sequences. These newly formed genomes can determine the fitness and survival of cells. In bacteria, homologous and non-homologous types of recombination lead to the evolution of new...

Tail-anchoring of Proteins in the ER Membrane
3.8K
Tail-anchored, or TA, proteins are estimated to make up to 3-5% of membrane proteins found in the eukaryotic cell. Such proteins have a single transmembrane domain located approximately 30 amino acid residues upstream from the C-terminal end. As a result, the signal recognition particle (SRP) cannot guide a TA protein to the ER membrane for cotranslational insertion. Hence, they are integrated into the ER membrane post-translationally using their C-terminal end as the anchor. TA proteins...

Gene Families
10.0K
Gene families consist of groups of genes proposed to have originated from a common ancestor. Typically these arise through events in which a gene or genes are mistakenly duplicated during cell division. Unlike their parent genes (which are subject to selection pressure to maintain function), these gene copies do not need to preserve their sequences and may evolve at a relatively faster rate.
Occasionally these regions can be adapted to take on new roles within the organism, becoming novel genes...

What is Gene Expression?
196.9K
Overview
Gene expression is the process in which DNA directs the synthesis of functional products, that is, proteins. Cells can regulate gene expression at various stages. It allows organisms to generate different cell types and enables cells to adapt to internal and external factors.
Genetic Information Flows from DNA to RNA to Protein
A gene is a stretch of DNA that serves as the blueprint for functional RNAs and proteins. Since DNA is made up of nucleotides and proteins consist of amino...
