Overview
The exact pathogenesis of [disease name] is not fully understood.
OR
It is thought that [disease name] is the result of / is mediated by / is produced by / is caused by either [hypothesis 1], [hypothesis 2], or [hypothesis 3].
OR
[Pathogen name] is usually transmitted via the [transmission route] route to the human host.
OR
Following transmission/ingestion, the [pathogen] uses the [entry site] to invade the [cell name] cell.
OR
[Disease or malignancy name] arises from [cell name]s, which are [cell type] cells that are normally involved in [function of cells].
OR
The progression to [disease name] usually involves the [molecular pathway].
OR
The pathophysiology of [disease/malignancy] depends on the histological subtype.
Pathophysiology
Physiology
The normal physiology of [name of process] can be understood as follows:
Pathogenesis
- The exact pathogenesis of [disease name] is not completely understood.
OR
- It is understood that [disease name] is the result of / is mediated by / is produced by / is caused by either [hypothesis 1], [hypothesis 2], or [hypothesis 3].
- [Pathogen name] is usually transmitted via the [transmission route] route to the human host.
- Following transmission/ingestion, the [pathogen] uses the [entry site] to invade the [cell name] cell.
- [Disease or malignancy name] arises from [cell name]s, which are [cell type] cells that are normally involved in [function of cells].
- The progression to [disease name] usually involves the [molecular pathway].
- The pathophysiology of [disease/malignancy] depends on the histological subtype.
Genetics
- The recent advancing analyses have made us understand the pathophysiology of some of these tumor subtypes
- Mutations mainly involving DICER1, STK11, and FOXL2 influence the development of some of these neoplasms
- FOXL2 is a tumor suppressor gene
- It is a member of the forkhead box (FOX) family of evolutionarily conserved transcription factors
- It plays a fundamental and essential role in ovarian development
- Almost all adult granulosa cell tumors are characterized by missense somatic point mutations (402 C→G) in FOXL2 gene
- Infact this mutation is a sensitive and specific biomarker for adult granulosa cell tumors
- Importantly this mutation alter's antiproliferative pathways and also limit the apoptosis, as a result contributing to the pathogenesis of adult granulosa cell tumors
Associated Conditions
Conditions associated with [disease name] include:
- [Condition 1]
- [Condition 2]
- [Condition 3]
Gross Pathology
On gross pathology, [feature1], [feature2], and [feature3] are characteristic findings of [disease name].
Microscopic Pathology
On microscopic histopathological analysis, [feature1], [feature2], and [feature3] are characteristic findings of [disease name].
