Summary
This summary is machine-generated.Cellular plasticity in pancreatic cancer involves cell identity changes. The receptor tyrosine kinase ROR2 drives aggressive pancreatic ductal adenocarcinoma (PDAC) and resistance to KRAS inhibitors.
Area Of Science
- Oncology
- Cell Biology
- Molecular Biology
Background
- Cellular plasticity is crucial in pancreatic ductal adenocarcinoma (PDAC) development and progression.
- Normal acinar cell differentiation, regulated by PDX1, normally suppresses a gastric cell identity.
Purpose Of The Study
- To investigate the role of cellular identity in PDAC.
- To identify regulators of cell plasticity and therapeutic targets in PDAC.
Main Methods
- Analysis of mouse and human pancreatic cancer samples.
- Genetic manipulation (ablation of Ror2) in mouse models.
- Investigation of receptor tyrosine kinase ROR2 function.
Main Results
- A gastric cell identity is present in PDAC precursors and the classical PDAC subtype.
- ROR2 marks a gastric metaplasia-like identity and antagonizes gastric pit cell identity.
- ROR2 ablation promotes gastric pit cell identity and alters PDAC progression.
- ROR2 promotes epithelial to mesenchymal transition, KRAS inhibitor resistance, and AKT inhibitor vulnerability.
Conclusions
- ROR2 is a key regulator of cellular identity in pancreatic precancerous lesions and PDAC.
- ROR2 drives aggressive PDAC phenotypes and confers resistance to KRAS inhibitors.
- Targeting ROR2 may enhance sensitivity to KRAS-targeted therapies.

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...
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...
Positive regulators allow a cell to advance through cell cycle checkpoints. Negative regulators have an equally important role as they terminate a cell’s progression through the cell cycle—or pause it—until the cell meets specific criteria.
Three of the best-understood negative regulators are p53, p21, and retinoblastoma protein (Rb). The regulatory roles of each of these proteins were discovered after faulty copies were found in cells with uncontrolled replication (i.e.,...
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,...
The mammalian target of rapamycin (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1 (mTORC1) and mTOR complex 2 (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast, mTORC2 consists of a...
The Ras-gene-encoded proteins are regulators of signaling pathways controlling cell proliferation, differentiation, or cell survival. The Ras-gene family in humans constitutes three primary members—the HRas, NRas, and KRas. These genes code for four functionally distinct yet closely related proteins—the HRas, NRas, KRas4A, and KRas4B. The involvement of mutant Ras genes in human cancer was first discovered in 1982 and is among the most common causes of human tumorigenesis.
Ras is a...
