The inaugural issue of Biobanking Weekly is coming to you just as the Global Biobank Week is closing providing leaders at the cutting edge of Biobanking to set the agenda for the months ahead. Important developments in biobanking this week include contributions to understanding of type 1 diabetes, the risks of 9/11 responders to fall victim to human papilloma virus (HPV) related head and neck cancers, new targets for osteoporosis treatment, advances in banking prostate cancer samples, the use of cystic fibrosis biobanks, the testing of drones for sample delivery, and the adoption of lean sigma six for efficient management and distribution of samples. Very exciting developments with plenty more forecast for the coming weeks.
Alpinia officinarum or lesser galangal (高良姜), is a member of the ginger family, which originates from China and is now cultivated throughout Southeast Asia (Figure 1). The roots are known as galangal and are used in cooking, perfumes and are also known for their medicinal properties. Alnus japonica or East Asian alder (日本桤木), is a species of tree found in Japan, Korea, and eastern China, stretching to Russia. Diarylheptanoids, the family of which the anti-cancer agent curcumin from turmeric is a member, can be extracted from these plants. Diarylheptanoid compounds from these medicinal plants were found to inhibit the growth of the PANC-1 (KRAS heterozygous G12D, TP53 homozygous P72R and R273H) pancreatic cancer cell line [1, 2]. The mechanism was proposed to derive from inhibiting the FoxM1 transcription factor signalling axis.
FoxM1 is a transcription factor of central importance to pancreatic cancer . It promotes the transcription of genes involved in cell cycle progression and cell survival as well as migration and invasion . FoxM1 transcription has been demonstrated to be promoted by the sonic hedgehog pathway in colorectal cancer and furthermore the hedgehog pathway is almost universally upregulated in pancreatic cancer [5, 6]. Dong et al. proposed that FoxM1 target genes are downregulated in response to the diarylheptanoid compounds due to Gli1/2 protein downregulation. Interestingly Stat3 signalling has been found to be downregulated by other diarylheptanoid compounds such as HO-3867 and Stat3 transcription can be indirectly upregulated by Gli1 via IL-6 [7, 8]. The extent to which different diarylheptanoid compounds could inhibit both FoxM1 and Stat3 axes in pancreatic cancer is an open question.

Paeonol, 1-(2-Hydroxy-4-methoxyphenyl) ethanone (figure 1) is a phenolic compound found in peonies such as Paeonia suffruticosa (moutan cortex), in Arisaema erubescens, and in Dioscorea japonica. It is a component of some traditional Chinese medicines .
|Figure 1: Paeonol, 1-(2-Hydroxy-4-methoxyphenyl) ethanone.
Paeonol has been demonstrated to induce apoptosis in a wide range of cancers including ovarian, gastric, colon, esophageal, hepatocellular, breast, melanoma, prostate and lung [2, 3, 4, 5, 6, 7, 8, 9, 10].
Paeonol appears to have anti-inflammatory and possibly anti-fibrotic capacity. In CW-2 large intestine carcinoma cell line paeonol inhibited tumor necrosis factor alpha (TNFα)-induced transcriptional activity of NF-κB and interferon gamma (IFNγ) induction of STAT1 . It may also have an inhibitory effect on STAT3 . In colon cancer cells paeonol was found to increase RUNX3 expression levels. RUNX3 has a complex role in the fibrosis promoting process of epithelial to mesenchymal transition (EMT), however at least in certain contexts RUNX3 prevents EMT [12, 13]. Drug resistance and immunosuppression are associated with EMT.
Importantly paeonol was found to alleviate drug resistance. It enhanced the efficacy of cisplatin , doxorubicin , and paclitaxel . These effects may be mediated through inhibition of the Akt pathway  in addition to any anti-fibrotic mechanism of action.
Paeonol can potentially “heat up” the immunosuppressive microenvironment of immunotherapy resistant tumours as it has been found to reduce the expression of Cyclooxygenase-2 (COX-2) and therefore reduce the levels of its metabolite prostaglandin E2 (PGE2) . PGE2 is known to promote the presence of active myeloid-derived suppressor cells (MDSC) within the tumour microenvironment which inhibit CD4+ and CD8+ T cells . Paeonol may therefore be synergistic with the new class of cancer immunotherapeutics.

STATs are transcription factors which are normally present in the cytoplasm and activated by inflammatory signalling associated with epithelial to mesenchymal transition (EMT) which leads to their nuclear import . STAT3 expression is maintained and constitutive activation has been reported in at least 30% of pancreatic cancers .
Fatty acid synthase (FASN) is a key enzyme involved in lipogenesis and the production of long-chain fatty acids from acetyl-coenzyme A (CoA) and malonyl-CoA which is crucial for rapidly growing cancer cells including pancreatic . The inhibition of fatty acid synthase is known to increase reactive oxygen species (ROS) levels in cancer which is associated with apoptosis .
Focal Adhesion Kinase (FAK) inhibitors demonstrated in preclinical pancreatic cancer models increased mouse survival time via tumour stasis, reduced collagen deposition and reduced numbers of activated fibroblasts, down-regulated gene expression of fibrosis associated markers, reduced cancer stem-like cell numbers, reduced numbers of immunosuppresive cells within tumours, synergized with gemcitabine treatment, synergized with adoptive T cell transfer to reduce tumour volume and was associated with increased numbers of therapeutic T cell in the tumour and synergised with checkpoint inhibitors under certain circumstances .
|Figure 1: HO-3867 mechanisms of action in cancer cells. HO-3867 down-regulates FASN and FAK protein expression leading to apoptosis and decreased cell migration respectively. HO-3867 also inhibits STAT3 phosphorylation which leads to apoptosis and possibly decreased cell migration.
The curcumin analog HO-3867 has recently been shown to inhibit STAT3 and down-regulate fatty acid synthase in pancreatic cancer cells leading to apoptosis via ROS . In addition in ovarian cancer models HO-3867 down-regulates FAK . The potential to inhibit STAT3, FASN and FAK with a single agent is very promising and warrants further investigation as a potential therapeutic for pancreatic cancer (Figure 1).
