The Retinoblastoma Gene01:20

The Retinoblastoma Gene

4.0K
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

Abnormal Proliferation02:23

Abnormal Proliferation

4.4K
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...

mTOR Signaling and Cancer Progression

3.7K
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...

Area of Science:

  • Urology
  • Oncology
  • Pathology

Background:

  • Oncocytic papillary renal cell carcinoma (OPRCC) is a rare subtype of papillary renal cell carcinoma (PRCC), newly recognized in the 2016 WHO Classification.
  • The distinct morphological, immunophenotypic, genetic, and prognostic features of OPRCC remain largely uncertain, complicating diagnosis and management.
  • Papillary renal cell carcinoma (PRCC) encompasses various subtypes, necessitating precise differentiation for effective patient care.

Observation:

  • Two cases of OPRCC treated surgically at the authors' institution are presented.
  • The clinical information, treatment course, and outcomes for these two patients are detailed.
  • A comprehensive literature review on OPRCC diagnosis and post-operative research progress is included.

Findings:

  • The study aims to delineate OPRCC as a distinct entity within the broader PRCC classification.
  • Current diagnostic and treatment strategies for OPRCC are reviewed based on case experience and literature.
  • Post-operative research advancements relevant to OPRCC are discussed.

Implications:

  • Enhanced understanding and precise diagnosis of OPRCC can lead to optimized, individualized patient management.
  • Clarifying the characteristics of OPRCC may improve treatment strategies and patient outcomes.
  • This review contributes to the growing body of knowledge on rare renal cell carcinoma subtypes.
