Insights

Anaplastic lymphoma kinase (ALK) is a receptor tyrosine kinase crucial in normal cell functions and cancer development. This review details ALK expression, fusion proteins, activation mechanisms, and targeted therapies for ALK-positive cancers.

Area of Science:

  • Oncology
  • Molecular Biology
  • Biochemistry

Background:

  • Receptor tyrosine kinases (RTKs) regulate vital cellular processes like proliferation, survival, and differentiation.
  • Dysregulation of RTKs is implicated in the pathogenesis of numerous human cancers.
  • The anaplastic lymphoma kinase (ALK) is a transmembrane RTK identified as a key player in various cancers.

Purpose of the Study:

  • To review the expression patterns of ALK-RTK and its associated fusion proteins.
  • To elucidate the molecular mechanisms underlying ALK activation in tumorigenesis.
  • To briefly discuss emerging therapeutic strategies for ALK-driven neoplasms.

Main Methods:

  • Literature review of ALK expression, function, and therapeutic targeting.
  • Analysis of molecular mechanisms of ALK activation and fusion protein formation.
  • Synthesis of current knowledge on ALK-positive cancer pathogenesis.

Main Results:

  • ALK expression and aberrant activation through fusion proteins are critical in several human cancers.
  • Understanding ALK's molecular mechanisms provides insights into its oncogenic potential.
  • Targeted therapies show promise for ALK-positive malignancies.

Conclusions:

  • ALK is a significant oncogenic driver in various cancers.
  • Targeted inhibition of ALK represents a promising therapeutic avenue.
  • Further research into ALK biology and treatment is warranted.

mTOR Signaling and Cancer Progression03:03

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 Intrinsic Apoptotic Pathway01:31

The Intrinsic Apoptotic Pathway

Internal cellular stress, such as cellular injury or hypoxia, triggers intrinsic apoptosis. The B-cell lymphoma 2 (Bcl-2) family of proteins are the primary regulators of the intrinsic apoptotic pathway. For example, during DNA damage, checkpoint proteins, such as Ataxia Telangiectasia Mutated (ATM protein) and Checkpoints Factor-2 (Chk2) proteins, are activated. These proteins phosphorylate p53 which further activates pro-apoptotic proteins, such as Bax, Bak, PUMA, and Noxa, and inhibits...
Abnormal Proliferation02:23

Abnormal Proliferation

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 daughter...
PI3K/mTOR/AKT Signaling Pathway01:22

PI3K/mTOR/AKT Signaling Pathway

The mammalian target of rapamycin  (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1  (mTORC1) and mTOR complex 2  (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast,  mTORC2 consists of a rapamycin-insensitive companion...
lncRNA - Long Non-coding RNAs02:39

lncRNA - Long Non-coding RNAs

In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA (lncRNA)...
Mitogens and the Cell Cycle02:38

Mitogens and the Cell Cycle

Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...
