Summary
Semaphorins are proteins crucial for development, guiding neural circuits, bone formation, and blood vessel growth. Their signaling pathways fine-tune cell behavior, impacting shape, movement, and survival.
Area of Science:
- Molecular Biology
- Developmental Biology
- Cell Signaling
Background:
- Semaphorins are secreted and membrane-associated proteins.
- They regulate key developmental processes like neural circuit assembly, bone formation, and angiogenesis.
- Semaphorin signaling involves trans and cis interactions with multimeric receptors.
Purpose of the Study:
- To provide an overview of semaphorin signaling molecular biology.
- To contextualize semaphorin signaling within specific cell and developmental processes.
- To highlight mechanisms controlling semaphorin effects.
Main Methods:
- Review of molecular biology principles.
- Analysis of semaphorin signaling pathways.
- Integration of data from accompanying poster.
Main Results:
- Semaphorin-receptor interactions trigger intracellular signal transduction.
- These networks regulate cytoskeletal dynamics.
- Cellular processes influenced include shape, differentiation, motility, and survival.
Conclusions:
- Semaphorin signaling is a complex network essential for development.
- Fine-tuning, diversification, and spatiotemporal control mechanisms modulate semaphorin actions.
- Understanding these mechanisms is key to comprehending developmental processes.

1.8K
Erythropoietin-producing hepatocellular carcinoma receptor (Eph) and its ligand, Eph receptor-interacting protein (Ephrin) were first discovered in the human carcinoma cell line, hence the name. Ephrin-Eph interaction guides cells to reach their appropriate location in adult tissues. They also play an essential role in the immune system by helping in immune cell migration, adhesion, and activation. Based on their structure and function, Eph is divided into two classes — EphA and EphB.

02:33Hedgehog Signaling Pathway
7.1K
The Hedgehog gene (Hh) was first discovered due to its control of the growth of disorganized, hair-like bristles phenotype in Drosophila, much like hedgehog spines. Hh plays a crucial role in the development of organs and the maintenance of homeostasis in both invertebrates and vertebrates. However, while Drosophila has only one Hh protein, mammals have multiple functional Hedgehog proteins - Sonic (Shh), Desert (Dhh), and Indian Hedgehog (Ihh). All of these homologous proteins have adapted to...

01:51Determination
16.3K
During embryogenesis, cells become progressively committed to different fates through a two-step process: specification followed by determination. Specification is demonstrated by removing a segment of an early embryo, “neutrally” culturing the tissue in vitro—for example, in a petri dish with simple medium—and then observing the derivatives. If the cultured region gives rise to cell types that it would normally generate in the embryo, this means that it is specified. In...

03:14Notch Signaling Pathway
4.6K
The Notch signaling pathway is a major intracellular signaling pathway that is highly conserved over a broad spectrum of metazoan species. It stands unique from other intracellular signaling mechanisms in animals because notch protein itself acts as the receptor as well as the primary signaling molecule.
The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not...

01:22Microtubules in Signaling
1.5K
The primary cilium, made up of microtubules, acts as antennae on the cell surfaces for relaying external stimuli into the cells. These fine hair-like structures are present, generally one per cell. These are non-motile cilia in a 9+0 microtubules arrangement, where the central pair of microtubules are absent. The primary cilia arise from the basal body embedded in the cell membrane. Intraflagellar transport (IFT) carries requisite proteins from the cytoplasm to the cilium because the primary...
