Adrenergic Receptors: ɑ Subtype01:31

Adrenergic Receptors: ɑ Subtype

2.3K
Adrenoceptors are classified into α and ꞵ classes based on their potencies to catecholamine agonists. α-adrenoceptors show the following order of catecholamine potency:
Adrenaline ≥ Noradrenaline >> Isoprenaline
α-adrenoceptors are further divided into α1 and α2-adrenoceptors.
α1-Adrenoceptors: These receptors are located postsynaptically on the effector organs and cause constriction of smooth muscle mediated by activation of phospholipase...

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

4.0K
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...

Abnormal Proliferation02:23

Abnormal Proliferation

4.8K
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

The Ras Gene02:38

The Ras Gene

6.6K
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.
Ras is a...

Assembly of Signaling Complexes01:30

Assembly of Signaling Complexes

6.1K
Multiprotein signaling complexes are formed in a dynamic process involving protein-protein interactions at the cytoplasmic domain of transmembrane receptors or enzymatic and non-enzymatic proteins associated with the receptor. These complexes ensure the activation and propagation of intracellular signals that regulate cell functions.
Interaction domains in cell signaling
Interaction domains recognize exposed features of their binding partners containing post-translationally modified sequences,...

  • Meta-analysis of independent primary PCa genomic databases.
  • Examination of co-occurring alterations and their combinatorial effects on the AR axis.

Main Results:

  • Identified common genomic alterations in primary PCa influencing AR axis.
  • Discovered distinct subtypes of co-occurring genomic alterations.
  • Demonstrated varied effects of these subtypes on AR activity and potential for therapy resistance.

Conclusions:

  • Primary PCa genomic alterations significantly impact AR signaling pathways.
  • Specific genomic subtypes may predict response or resistance to AR-targeted therapies.
  • Patient tumor genetics could be a key factor in stratifying treatment for advanced PCa.
