Insights

Ras association domain family 7 (RASSF7) is implicated in various cancers. This review explores RASSF7

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • Ras association domain family 7 (RASSF7), also known as HRC1, is located on human chromosome 11p15.
  • RASSF7 is a key member of the N-terminal RASSF family with a potential role in tumorigenesis.
  • The precise molecular mechanisms of RASSF7 in cancer development require further elucidation.

Purpose of the Study:

  • To systematically review the literature on RASSF7's role in tumorigenesis.
  • To elaborate on RASSF7's structure, biomechanisms, and signaling pathways.
  • To assess RASSF7 as a potential therapeutic target for human malignancies.

Main Methods:

  • Systematic literature review of PUBMED and MEDLINE databases.
  • Assessment of existing research on RASSF7's biological functions and involvement in cancer.
  • Analysis of RASSF7's regulatory roles in key cellular processes and signaling pathways.

Main Results:

  • RASSF7 significantly influences mitosis, microtubule growth, apoptosis, proliferation, and differentiation.
  • RASSF7 can promote tumor development by regulating pathways involving Aurora B, MKK4/7, JNK, YAP, MEK, and ERK.
  • RASSF7 may inhibit tumorigenesis by suppressing c-Myc, and its dysregulation is observed in lung, breast, and gastric cancers, among others.
  • RASSF7 expression correlates positively with tumor TNM stage.

Conclusions:

  • RASSF7 plays a multifaceted role in cancer, potentially acting as both an oncogene and a tumor suppressor depending on the context.
  • Understanding RASSF7's complex regulatory networks is crucial for developing targeted cancer therapies.
  • RASSF7 represents a promising therapeutic target for various human malignancies.

The Ras Gene02:38

The Ras Gene

The Ras-gene-encoded proteins are regulators of signaling pathways controlling cell proliferation, differentiation, or cell survival. The Ras-gene family in humans constitutes three primary members—the HRas, NRas, and KRas. These genes code for four functionally distinct yet closely related proteins—the HRas, NRas, KRas4A, and KRas4B. The involvement of mutant Ras genes in human cancer was first discovered in 1982 and is among the most common causes of human tumorigenesis.

Rab Cascades01:25

Rab Cascades

Rab GTPases act in a regulated cascade during membrane fusion, helping the lipid bilayers mix. The Rab family of proteins are active when bound to GTP, and inactive when bound to GDP. Hence, they act as guanine nucleotide-dependent molecular switches. Rab-GTP recognizes and binds to long or short-range tethering proteins to capture the target vesicle. These tethers coordinate with SNAREs on the vesicle and the target membrane to assemble the trans SNARE complex that locks the mixing bilayers.

MAPK Signaling Cascades01:07

MAPK Signaling Cascades

Mitogen-activated protein kinase, or MAPK pathway, activates three sequential kinases to regulate cellular responses such as proliferation, differentiation, survival, and apoptosis. The canonical MAPK pathway starts with a mitogen or growth factor binding to an RTK. The activated RTKs stimulate Ras, which recruits Raf or MAP3 Kinase (MAPKKK), the first kinase of the MAPK signaling cascade. Raf further phosphorylates and activates MEK or MAP2 Kinases (MAPKK), which in turn phosphorylates MAP...

Small GTPases - Ras and Rho01:24

Small GTPases - Ras and Rho

Ras and Rho are small monomeric GTPases that act downstream of receptor tyrosine kinase (RTK) and regulate various cellular processes. These GTPases switch between active and inactive states by binding to guanine nucleotides.
Three regulatory proteins control their activity:

Rab Proteins01:14

Rab Proteins

Rab proteins constitute the largest family of monomeric GTPases, of which 70 members are present in humans. Rab proteins and their effectors regulate consecutive stages of vesicle transport such as vesicle transport, docking, and fusion to the correct recipient membrane.
Rab proteins switch between a cytosolic, GDP-bound inactive state and a membrane-anchored, GTP-bound active state. By themselves, Rabs show slow rates of GDP/GTP exchange and GTP hydrolysis. Thus, Rab proteins are considered...

Rous Sarcoma Virus (RSV) and Cancer01:03

Rous Sarcoma Virus (RSV) and Cancer

Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand  RNA genome. Its genome consists of four main open...
