AI Article Synopsis

  • Salivary gland pleomorphic adenomas often show chromosome abnormalities at 8q12, raising questions about their connection to tumor development.
  • DNA from eight adenomas with these abnormalities was analyzed for changes in the proto-oncogene c-mos, which is located near the affected area.
  • The study found no rearranged c-mos alleles in any of the tumors, only the normal germ-line fragments.

Article Abstract

The frequent occurrence of salivary gland pleomorphic adenomas characterized by clonal structural chromosome abnormalities involving 8q12 raises the question as to how the cytogenetic rearrangements correspond to molecular mechanisms of tumor development. Since the proto-oncogene c-mos maps to this breakpoint region, DNA from eight adenomas with these aberrations was isolated and checked for rearrangements of c-mos after digestion by BamHI, EcoRI and HindIII. In none of the tumors was a rearranged allele besides the germ-line fragments found.

Survival benefit of cancer-directed surgery and the role of adjuvant therapy in malignant major salivary gland cancers: a propensity score matched retrospective analysis.

Oral Maxillofac Surg

Background: The primary objective of this study was to assess the benefit of cancer-directed surgery (CDS) on both overall survival (OS) and cancer-specific survival (CSS) of patients with malignant major salivary gland cancers (MMSGCs). The secondary objective was to explore the benefits of adjuvant therapy on the survival outcomes of these patients.

Methods: Patients diagnosed with MMSGC were extracted from the SEER database and subsequently categorized into two cohorts: CDS and non-CDS.

Median mandibular cyst is defined as an odontogenic cyst in a rare midline location. In spite of this definition, there have been two reports of a peculiar lesion, so-called "ciliated" median mandibular cyst associated with vital teeth, the origin of which cannot be explained in terms of odontogenic epithelium multipotentiality. We describe a thorough profile of an additional example.

Ant-eating mammals represent a textbook example of convergent evolution. Among them, anteaters and pangolins exhibit the most extreme convergent phenotypes with complete tooth loss, elongated skulls, protruding tongues, and hypertrophied salivary glands producing large amounts of saliva. However, comparative genomic analyses have shown that anteaters and pangolins differ in their chitinase acidic gene (CHIA) repertoires, which potentially degrade the chitinous exoskeletons of ingested ants and termites.

Background: Endoplasmic reticulum stress (ERS) and the unfolded protein response (UPR) are adaptive mechanisms for conditions of high protein demand, marked by an accumulation of misfolded proteins in the endoplasmic reticulum (ER). Rheumatic autoimmune diseases (RAD) are known to be associated with chronic inflammation and an ERS state. However, the activation of UPR signaling pathways is not completely understood in Sjögren's disease (SD).
