Summary
Lung cancer progenitor cells have distinct kinase profiles. Their kinomes change upon transformation into lung adenocarcinomas and squamous cell carcinomas, revealing lineage-specific reprogramming.
Area of Science:
- Molecular biology
- Cancer research
- Cell biology
Background:
- Mutant tyrosine kinases are key drivers in lung adenocarcinoma development and therapy.
- The kinome of lung cancer progenitor cells and its reprogramming during transformation remain poorly understood.
Purpose of the Study:
- To investigate the kinome differences between lung cancer progenitor cells (alveolar type II cells and basal cells) and their transformed counterparts.
- To determine if kinome reprogramming is lineage-specific during lung cancer development.
Main Methods:
- RNA sequencing was performed on freshly isolated human alveolar type II cells, basal cells, and lung cancer cell lines.
- Comparative analysis of kinome expression in non-transformed progenitor cells and transformed carcinoma cells.
Main Results:
- Distinct kinome profiles were identified for alveolar type II cells and basal cells.
- Significant changes in kinome expression were observed upon transformation of these progenitor cells into their respective carcinomas.
Conclusions:
- Lung cancer progenitor cells possess unique kinomes that are altered during malignant transformation.
- These findings highlight lineage-specific kinome reprogramming in lung cancer, offering potential therapeutic targets.

01:05Type IV Collagen of Basal Lamina
3.0K
Type IV collagen is a 400 nm long, network-forming collagen that acts as a barrier between the epithelial and endothelial cells. Type IV collagen forms the backbone of the basement membrane by scaffolding with laminin, entactin, proteoglycans, and fibronectin. Apart from rendering structural support to the basement membrane, it also helps entail signaling potentials necessary for both pathological and physiological functions.

01:29Somatic to iPS Cell Reprogramming
2.6K
Reprogramming alters the gene expression in somatic cells, transforming them into induced pluripotent stem (iPS) cells over several generations. Scientists can reprogram cells by introducing genes for four transcription factors—Oct4, Sox2, Klf4, and c-Myc (OSKM) by viral or non-viral methods. These factors are also known as Yamanaka factors after Shinya Yamanaka, who first generated iPS cells using mouse skin cells. Yamanaka was awarded the Nobel Prize in Physiology or Medicine in 2012...

01:26Alveoli and Alveolar Ducts
5.6K
The respiratory zone of the human body, which stands in contrast to the conducting zone, comprises the structures that actively participate in the exchange of gases. The initiation of this zone is marked by the terminal bronchioles converging into respiratory bronchioles, the tiniest bronchiole classification. The respiratory bronchioles give way to the alveolar ducts that opens into a congregation of alveoli. Actively involved in gas exchange, alveoli resemble tiny sacs similar to clusters of...

00:55Laminins are the Adhesive Proteins of Basal Lamina
3.1K
Laminins are heterotrimeric proteins with high molecular mass found in the extracellular matrix. Each laminin molecule is composed of three chains, viz. alpha, beta, and gamma, coded by five, four, and three paralogous genes, respectively. Laminins are categories based on the compositions of the three chains.
In humans, the five forms of alpha chains are LAMA 1, LAMA 2, LAMA 3, LAMA 4, and LAMA 5. The four forms of beta chains are LAMB 1, LAMB 2, LAMB 3, and LAMB 4. The three forms of gamma...

01:03Basal Lamina are the Specialized Form of ECM
3.7K
The basal lamina is a thin extracellular layer that lies underneath the cells and separates them from other tissues. The three layers of the basal lamina are lamina lucida, lamina densa and lamina reticularis. The basal lamina, a mixture of glycoproteins and collagen, provides an attachment site for the epithelium, separating it from underlying connective tissue. The framework of basal lamina has other essential proteins such as laminins mesh, perlecan, entactin, and type IV collagen.

56.2K
The air in the lungs is measured in volumes and capacities. Lung volume measures reflect the amount of air taken in, released, or left over after a lung function, like a single inhalation. Lung capacity measures are sums of two or more lung volume measures.
