Pancreatic cysts are a heterogeneous group of lesions, which can be benign or malignant. Due to improved imaging techniques, physicians are more often confronted with pancreatic cysts. Little is known about the origin of pancreatic cysts in general. Von Hippel-Lindau (VHL) disease is an atypical ciliopathy and inherited tumor syndrome, caused by a mutation in the VHL tumor suppressor gene encoding the VHL protein (pVHL). VHL patients are prone to develop cysts and neuroendocrine tumors in the pancreas in addition to several other benign and malignant neoplasms. Remarkably, pancreatic cysts occur in approximately 70% of VHL patients, making it the only hereditary tumor syndrome with such a discernible expression of pancreatic cysts. Cellular loss of pVHL due to biallelic mutation can model pancreatic cystogenesis in other organisms, suggesting a causal relationship. Here, we give a comprehensive overview of various pVHL functions, focusing on those that can potentially explain pancreatic cyst development in VHL disease. Based on preclinical studies, cilia loss in ductal cells is probably an important early event in pancreatic cyst development.

Pancreatic cysts are frequent, with a prevalence of 2.4 to 13.5% in patients without known pancreatic disease. Due to increased use of cross-sectional imaging techniques, physicians are more frequently confronted with pancreatic cysts . Various types of pancreatic cysts can occur, which can be benign or have malignant potential. An expectative policy is accepted for benign cysts and surgery is indicated for malignant lesions. Currently, accurate diagnostics are not available to identify malignant cysts . Despite the need for mechanistic insight, little is known about the origin and pathophysiology of pancreatic cysts in general.
pNETs are present in 10 to 17% of VHL patients [8, 9] and pancreatic cysts occur in about 70% [10, 11]. Because of this high prevalence, it is worthwhile examining the early cellular events that result in pancreatic cysts in VHL disease, reflecting insight into pancreatic cystic disorders in general. In this review, we conduct a complete overview of pVHL functions to explain cellular events involved in cyst development in the context of VHL. Based on knock-out mouse models, we discuss the consequences of Vhlh loss in the pancreas and the origin of pancreatic cysts.

VHL disease classification
The clearest genotype-phenotype correlation is exemplified by type 2 VHL, typically characterized by a VHL missense mutation and presence of pheochromocytomas [27, 28]. Type 1 VHL is more frequently characterized by a VHL truncating mutation and absence or rare occurrence of pheochromocytomas. Type 2 VHL alleles can be further subdivided based on absence or presence of RCC; called VHL type 2A and type 2B, respectively [28, 29]. A pheochromocytoma-only subtype has also been described: VHL type 2C . Pancreatic involvement occurs in both VHL type 1 and type 2B, although it is unclear whether it occurs in the rare VHL types 2A and 2C .
The VHL gene was identified in 1993  and is a tumor suppressor gene; somatic inactivation of the wild-type allele or loss of heterozygosity (LOH) of the VHL gene is often observed prior to development of VHL-associated lesions [33, 34]. Consisting of three exons, the human VHL gene is located on chromosome 3 (3p26-p25), encoding a 213-amino acid pVHL (30 kDa VHLp30) and a 160-amino acid shorter form (19 kDa VHLp19) [35, 36]. The role of VHL in the oxygen-sensing pathway is its best-characterized function: cellular normoxic conditions enable the pVHL E3 ubiquitin ligase complex to target the α-subunit of hypoxia inducible factor (HIF) for proteosomal degradation. During hypoxia, pVHL is not able to bind HIF-α, resulting in accumulation of un-ubiquitinated HIF-α, which then translocates to the nucleus. This stimulates the transcription of various genes, including VEGF.
Since pVHL is still capable of functioning within the E3 ubiquitin ligase complex in VHL type 2C , other pVHL functions must be present to induce tumorigenesis. Indeed, VHL also regulates the assembly of the extracellular matrix (ECM) [39–45], and recent studies have shown that pVHL regulates the microtubule cytoskeleton, particularly plus-end stability [46–54].
Sporadic pancreatic serous cystadenomas
Data suggest that VHL loss through LOH of chromosome 3p might be a common mechanism initiating cystogenesis in sporadic pancreatic cystadenomas [55, 56]. Recently, whole-exome sequencing was performed in various sporadic pancreatic cysts . Seven out of eight serous cystadenomas lost chromosome 3p alleles, and in four, VHL gene mutations were found. This further supports that VHL loss initiates cystogenesis in pancreatic cystadenomas. Given that loss of the VHL locus was the only recurrent lesion identified, these data indicate that VHL loss alone could be sufficient for this development. Interestingly, in this same study, intraductal papillary mucinous neoplasms, mucinous cystic neoplasms, and solid pseudopapillary neoplasms did not show alterations in 3p alleles. In these lesions other genes encoding E3 ubiquitin ligases were involved, pointing to protein turnover as an underlying mechanistic theme .
pVHL regulates cellular architecture
pVHL and the extracellular matrix
In a xenograft model using RCC cell lines, VHL-ECM, VHL-HIF or both pathways were inactivated. VHL−/− 786–0 cells expressing HIF-2α failed to assemble an ECM. VHL+/+ cells retrovirally infected to produce proteasome-resistant HIF-2α, were still able to assemble an ECM, indicating that it is independent of VHL-HIF regulation. Alternatively in VHL type 2C cells, mutant pVHL regulates HIF normally, but interferes with ECM assembly . Xenograft tumors from VHL type 2C cells were hypervascular and invasive, similar to tumors originating from VHL−/− 786–0 cells. In contrast, xenografts derived from VHL+/+ cells engineered to stabilize HIF-2α resulted in tumors with lower microvessel density and invasiveness, despite higher VEGF expression . Thus, upregulation of VEGF alone is not sufficient for hypervascularization of tumors. Kurban et al. suggested that a strong collagen IV network, dependent on pVHL, naturally suppresses tumorigenesis .
pVHL and cell polarity
Epithelial cells have asymmetric specification of membrane domains. Asymmetry and polarization are regulated by partitioning defective proteins (PAR) and atypical protein kinase C (aPKC). The PAR3-PAR6-aPKC complex is essential for establishing the apical membrane domain and junction structures of epithelial cells . In addition, this complex is involved in formation of the apical lumen in three-dimensional cultures .
The pVHL ubiquitin ligase complex targets the active form of aPKC for degradation, analogous to HIF-α . VHL mutant cells fail to form intercellular junctions, resulting in lost polarity . This may be due to deregulation of active aPKC. Moreover, pVHL associates with the PAR3-PAR6-aPKC complex . In a follicular epithelial model in Drosophila, loss of wild-type vhl resulted in epithelial disorganization, microtubule destabilization and subsequent aPKC mislocalization  (Figure 4). Duchi et al. concluded that loss of VHL in vivo can destabilize strict planar cell polarity control, resulting in architectural changes permissive to cyst development .
pVHL and microtubule dynamics
Microtubules are polymerized filaments composed of α- and β-tubulin monomers. Microtubules continuously shrink at their “minus-ends” and grow at their “plus-ends” . pVHL promotes microtubule stabilization by reducing tubulin turnover [46, 47, 54]; it binds microtubules through kinesin-2 . In vitro inhibition of tubulin GTP-ase activity by pVHL at microtubule plus-ends contributes to this stability, which is compromised by VHL patient-associated mutant alleles . Furthermore, cellular inactivation of pVHL results in spindle misorientation, spindle checkpoint weakening and chromosomal instability attributed to microtubule instability . Interestingly, pVHL directs growth of microtubule orientation towards the outer plasma membrane .
pVHL and cilia
Microtubules form the backbone of cilia, which project from the apical cell surface. Cilia sense outside the cell and are involved in signaling pathways. Intraflagellar transport of ciliary components is required for ciliary functions, which is powered by kinesin-2. The heterotrimeric motor kinesin-2 comprises motor subunits of kinesin superfamily protein 3 (KIF3A, KIF3B) and kinesin-associated protein 3 (KAP3) . pVHL binds KIF3A and KAP3 of kinesin-2 , and in the cell, mobility of pVHL is at least partially regulated by kinesin-2 .
In renal tissue from VHL patients, cilia are lost in cysts, while cilia are still present in normal tissue . Accordingly, RCC cell lines with or without reconstitution of wild-type VHL, show that pVHL contributes to ciliary maintenance and stability [51, 52]. Cilia loss in kidney tubules due to pVHL dysfunction likely results from disoriented microtubule growth and decreased microtubule stability , and is associated with renal cyst development (Figure 4) . It has not been confirmed that pancreatic cysts in VHL patients are the consequence of cilia loss. However, in a pancreatic-specific Kif3a knock-out mouse model, cyst development was attributed to cilia loss (see “Cilia loss in pancreatic cells in vivo”) . Therefore, it is likely that pancreatic cysts in VHL are a result of similar consequences.
Histopathology of the pancreas in VHL
Histology of pancreatic cysts and pNETs
Pancreatic cysts and pNETs in VHL disease have distinct features. pNETs have a solid, trabecular and/or glandular architecture with stromal collagen bands and neurosecretory dense core granules , which are absent in VHL pancreatic cysts . Immunohistochemical staining for chromogranin A, S-100, synaptophysin and neuron-specific enolase showed positive expression in VHL pNETs . Pancreatic cysts stained negative for chromogranin A and S-100 . The histology of 119 pancreatic cysts was examined in detail from nine VHL patients . All demonstrated a mixture of clear and/or amphophilic glycogen-rich epithelial cells, endothelial cells and smooth muscle cells. Cysts contained and were surrounded by fibrous tissue. In both pNETs and pancreatic cysts, LOH of VHL wild-type allele was confirmed [58, 69].
The pancreas in VHL mouse models
Constitutional inactivation of Vhlh results in embryonic lethality at 10.5 to 12.5 days of gestation, due to placental vasculogenesis defects . To investigate the development of VHL-associated pancreatic manifestations, conditional mouse models have been generated using Cre/LoxP technology . In other mouse models Vhlh, Hif-1α or both, were conditionally inactivated in pancreatic β-cells in order to investigate the role of pVHL in glucose metabolism [72–75].
In the first study , the Vhlh gene was inactivated in pancreatic progenitor cells by driving Cre recombinase with the Pdx-1 promoter. Postnatal death was observed in the Pdx1-Cre;Vhlh f/f mice (n = 22), of which 18 were dead within five days. Histological analyses by pathologists blinded for genotypes showed no abnormalities. However, five individual Pdx1-Cre;Vhlh f/f mice survived longer. At 6 to 7 months of age, no pancreatic abnormalities were found in two Pdx1-Cre;Vhlh f/f mice. The remaining three were sacrificed at 16 to 18 months of age. At this time point, pancreatic tissue was replaced by fat deposition and pancreatic cysts, and microcystic adenomas were present. The epithelial lining and endothelial cells of the microcystic adenomas expressed cytokeratin MAK6 and CD31, respectively, comparable to findings of pancreatic cysts in VHL patients . In Pdx1-Cre;Vhlh f/f mice, all pancreatic islets were characterized by complex and dilated hypervascularity. Some islets had a small, abnormally shaped appearance and others were hyperplastic . In another study Pdx1-Cre;Vhlh f/f mice were born in the normal Mendelian frequencies. At 12 months of age no cysts or tumors were seen, but a slightly increased pancreatic vascularization was present, compared to control mice .

Origin of pancreatic lesions in VHL
Whether pNETs originate from exocrine or endocrine cells remains unknown . In pancreatic tissue of 13 VHL patients who underwent surgery because of pNETs, microadenomas were found ranging from 1 to 25 per patient. Expression of cyclin D1, carbonic anhydrase 9 and HIF-1α suggests that these microadenomas occur due to LOH of VHL in clonal lesions, which might be an early stage of pNETs. Most microadenomas were located close to acinar cells, but were also found close to duct or islet cells .
In contrast, evidence exists that pancreatic serous cystadenomas originate from duct cells. In these cysts and duct cells, co-expression of cytokeratin patterns is present, as determined immunohistochemically [77, 78]. Moreover, of 38 serous cysts including two VHL-related, 70% stained positive for mucin 6 , which is also expressed in duct and essentially centro-acinar cells . This suggests a ductal/centro-acinar origin for pancreatic serous cysts .
Cilia loss in pancreatic cells in vivo
A study with conditionally inactivated Kif3a in pancreatic tissue in mice suggests that pancreatic cysts originate from duct cells, as a result of cilia loss . Pdx1-Cre early ;Kif3a f/f mice were sacrificed at different time points: at two days postnatal, loss of acini was observed and enhancement of lumen between acinar cells and interstitial cells in acini; at 15 days progressive lumen between acini and duct dilation were found. These pathologies all progressed with age and led to acinar tissue being replaced by adipose tissue, severe fibroses, fluid-filled cysts and extensive ductal dilation (age 6 to 12 months). Cilia were lacking in all pancreatic cells. To further identify the cells of origin, conditional knock-out mice were developed for Kif3a inactivation in islet cells only, as well as in islet and acinar cells. In mice lacking Kif3a in islet cells, no morphological abnormalities were observed. Cilia were only present in duct and reduced in islet cells, suggesting that pancreatic cysts originate from ductal cells .
We argue that VHL disease can serve as an excellent model to improve the understanding of pathophysiology of pancreatic cysts in general. In vitro studies support a role for pVHL in microtubule stabilization and subsequent cilia maintenance. Loss of cilia is directly related to renal cyst development in VHL and in other renal cystic syndromes . Other cell aspects are also involved; pVHL influences assembly of the extracellular matrix as well as the cytoskeleton, including cell polarity.
In Pdx1-Cre;Vhlh f/f mice with pancreatic-specific loss of Vhlh, pancreatic cysts were observed after 16 to 18 months . Conditional Kif3a knock-out in pancreatic duct cells in mice also resulted in cysts, but changes were already observed after 2 days . Assuming that cysts mainly result from cilia loss, these data suggest that loss of additional alleles might be necessary for Vhlh-driven pancreatic cyst development. In contrast, exome sequencing of sporadic human pancreatic serous cysts only found chromosome 3p loss/VHL mutations as recurrent genetic lesions, suggesting that VHL loss is sufficient for pancreatic cyst development. The high prevalence of pancreatic cysts in patients with VHL disease supports this notion. Differences in findings might be attributed to differences in species, since in general mice seem to be relatively resistant to VHL loss when compared to humans , indicating that in humans VHL loss alone might be sufficient for pancreatic serous cyst development.
Monogenetic diseases like VHL provide insights which can be translated to pancreatic cysts in general. Better understanding and identification of genes regarding pancreatic cyst development will probably provide new directions for diagnostics, follow-up and treatment options. Future studies should focus more on VHL and also other E3 ubiquitin ligase genes, which appear to be involved in pancreatic cysts.
