AI Article Synopsis

  • The study examined how keratin proteins change during tumor progression in the hamster cheek pouch, using DMBA as a carcinogen.
  • It found a notable decrease in 67 K keratins and an increase in 46 K keratins in hyperplastic and well-developed tumors compared to control samples.
  • The findings indicate a connection between low molecular weight keratins, increased tonofilament bundles, and the undifferentiated characteristic of oral tumors.

Article Abstract

The altered pattern in the expression of keratin proteins as a function of tumour progression was studied in the hamster cheek pouch and compared the changes with electron microscopic observations using DMBA as a carcinogen. In the case of hyperplasia and well developed tumours a conspicuous loss of 67 K and an increase in 46 K was observed compared to the controls. The increased expression of low molecular weight keratins during tumour growth is well supported by the enhanced expression of tonofilament bundles, electron microscopically. This study suggests a triangular relationship between the presence of low molecular weight keratins-enhanced expression of tonofilament bundles and the undifferentiated nature of the oral tumours.

Background/objectives: KRT23 was recently discovered as an epithelial-specific intermediate filament protein in the type I keratin family. Many studies have underlined keratin's involvement in several biological processes as well as in the pathogenesis of different diseases. Specifically, KRT23 was reported to affect the structural integrity of epithelial cells and to trigger cellular signaling leading to the onset of cancer.

The epithelial-mesenchymal transition (EMT) program is critical to metastatic cancer progression. EMT results in the expression of mesenchymal proteins and enhances migratory and invasive capabilities. In a small percentage of cells, EMT results in the expression of stemness-associated genes that provide a metastatic advantage.

Neural precursor cells contain two types of intermediate filaments (IFs): neurofilaments consisting of three IV type proteins and vimentin belonging to the type III IF proteins that disappear at the later stages of differentiation. The involvement of vimentin in neurogenesis was demonstrated earlier; however, the role of its temporary expression in neurons is not clear. We showed that the vimentin IFs that interacted with mitochondria maintained their membrane potential at the appropriate level, and thus, ensured their proper function.

Cellular distribution of some intermediate filaments in the rat mammary gland during pregnancy, lactation and involution.

Intermediate filaments (IFs) play a major role in determining and maintaining cell shape and anchoring intracellular organelles in place, in the tissues and organs of several species, starting from the early stages of development. This study was aimed at the immunohistochemical investigation of the presence, cellular localization and temporal distribution of the intermediate filaments keratin 8 (CK8), keratin 18 (CK18), keratin 19 (CK19), vimentin, desmin and laminin, all of which contribute to the formation of the cytoskeleton in the rat mammary gland during pregnancy, lactation and involution. On days 7, 14 and 21 of pregnancy (pregnancy period), on day 7 post-delivery (lactation period) and on day 7 post-weaning (involution period), under ketamine hydrochloride (Ketalar-Pfizer) (90 mg/kg) anesthesia, two mammary glands were fully excised from the abdominal region.

Article Synopsis
  • Cytoplasmic intermediate filaments (cIFs) play a crucial role in cell function and tissue homeostasis, yet their disturbances and effects are not well understood.
  • Using RNA interference (RNAi), researchers linked disruptions in cIFs to alterations in cellular processes like proliferation and differentiation, particularly in oral epithelium derived from alcohol-treated keratinocytes.
  • The study revealed that impairments in specific keratins and vimentin affect cellular behavior and nuclear integrity, suggesting a complex regulatory relationship between cIFs and keratinocyte differentiation markers, which could offer insights into maintaining tissue health.
