Canonical Wnt Signaling Pathway

Canonical Wnt Signaling Pathway

The gene encoding the main signaling molecules of the Wnt signaling pathways (the Wnt proteins) was discovered almost four decades ago by Nüsslein-Volhard and Wieschaus. They identified and originally named the gene "wingless" (wg) after a phenotype discovered during their landmark genetic screen in Drosophila for body pattern defects. At around the same time, another researcher named Harold Varmus found that a murine tumor virus activates the mammalian wg homolog, Int-1, which results in tumor...

mTOR Signaling and Cancer Progression

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...

Non-Canonical Wnt Signaling Pathways

Non-Canonical Wnt Signaling Pathways

Wnt is a zygotic effect gene that is expressed during very early embryonic development. It regulates various processes in animals starting from early development through the adult stage, such as organogenesis in the embryo and maintenance of neuronal and blood stem cells. Wnt proteins can induce a wide variety of intracellular pathways depending upon the specific abilities of different Wnt ligands to form a complex with shared and cognate receptors in the presence of different co-receptors. The...

TGF - β Signaling Pathway

TGF - β Signaling Pathway

The TGF-β signaling pathway regulates cell growth, differentiation, adhesion, motility, and development. TGF-β ligands that induce TGF-β signaling are synthesized in their latent form. Several proteases or cell surface receptors such as integrins act upon the latent form, releasing the active ligand. There are three types of mammalian TGF-βs: (TGF-β1, TGF-β2, and TGF-β3) that bind as homodimers or heterodimers to TGF-β receptors. The TGF-β receptors are of three kinds RI, RII, and RIII. The RI...

Background:

The Wilms' tumor 1 (WT1) gene is a known tumor suppressor implicated in Wilms' tumor and other cancers.
WT1 mutations are linked to congenital abnormalities like Denys-Drash and Frasier syndromes.
WT1 plays a vital role in the development of kidneys, gonads, and spleen.

Purpose of the Study:

To review the molecular mechanisms of WT1 isoforms in normal development.
To explore how WT1 alterations contribute to developmental abnormalities and tumorigenesis.

Main Methods:

Literature review of WT1 gene function and mutations.
Analysis of WT1 protein isoforms and their roles.
Examination of WT1's involvement in disease pathogenesis.

Main Results:

WT1 proteins function as transcriptional regulators and in RNA processing.
WT1 isoforms exhibit diverse biological functions dependent on tumor type.
Mutations in WT1 can lead to both tumor suppression and cell survival roles.

Conclusions:

WT1 gene is essential for normal organogenesis.
Dysregulation of WT1 contributes to developmental disorders and various cancers.
Understanding WT1 isoforms is key to deciphering its role in health and disease.
