Early detection of cancer recurrence using specific biomarkers remains a clinically unmet need, although methodologies for monitoring tumor markers, cell-free DNA, and circulating tumor cells have been established for decades. Tumor recurrence develops in metastatic or dormant cancer cells under continuous immune surveillance. Alterations in the population and function of immune cells may contribute to cancer recurrence.

Perineural invasion and neurogenesis are frequently observed in pancreatic ductal adenocarcinoma (PDAC) and link to poor outcome. However, how neural factors affect PDAC prognosis and the underlying mechanism as well as counteracting therapeutic are still unclear. systematic analysis was performed with PROGgene to identify potential neural factor and its receptor in pancreatic cancer.

Perineural invasion and neurogenesis are frequently observed in pancreatic ductal adenocarcinoma (PDAC), and they are associated with a poor prognosis. Axon guidance factor semaphorin 3A (SEMA3A) is upregulated in PDAC. However, it remains unclear whether cancer-derived SEMA3A influences nerve innervation and pancreatic tumorigenesis.

Article Synopsis
  • Tumor progression is influenced by both tumor cells and their surrounding microenvironment, so effective cancer therapies should target cancer cells while also boosting immune cell activity.* -
  • Arginine modulation plays a crucial role in cancer treatment; arginase inhibitors can activate T-cells by increasing arginine levels, while agents like ADI-PEG 20 deplete arginine in certain tumor cells, leading to an anti-tumor effect without harming normal immune cells.* -
  • Combining an arginase inhibitor (L-Norvaline) with ADI-PEG 20 shows promise in enhancing anti-tumor responses, particularly in melanoma, by increasing CD8 T cell infiltration and reducing immunosuppressive cell populations,

Article Synopsis
  • Liposomal irinotecan (nal-IRI) combined with 5-fluorouracil and leucovorin shows improved survival for pancreatic ductal adenocarcinoma (PDAC) patients after they progress from gemcitabine therapy.
  • A study of 667 patients analyzed the effects of starting doses and escalation of nal-IRI on survival and toxicity, categorizing them into standard and reduced doses with or without escalation.
  • Results indicated that patients with reduced doses followed by escalation had the longest treatment cycles and better overall survival compared to those on standard doses or reduced doses without escalation, although standard doses resulted in higher rates of severe side effects.

Article Synopsis
  • Liposomal irinotecan combined with 5-fluorouracil and leucovorin shows survival benefits in pancreatic ductal adenocarcinoma (PDAC) but also presents side effects, especially in patients resistant to gemcitabine.
  • The study examined the albumin and neutrophil-to-lymphocyte ratio score (ANS) as a tool to predict survival and safety in 434 PDAC patients treated with nal-IRI + 5-FU/LV.
  • Results indicated that higher ANS scores correlated with worse survival rates and increased treatment-related adverse events, confirming ANS as a significant predictor of outcomes in these patients.

The impact of spleen volume on the survival of metastatic pancreatic adenocarcinoma patients receiving nanoliposomal irinotecan.

Nanoliposomal irinotecan (nal-IRI) plus 5-fluorouracil and leucovorin (NalFL) comprises the current standard for gemcitabine-failed metastatic pancreatic ductal adenocarcinoma (PDAC). As liposomes generally accumulate in the spleen, we evaluated the impact of spleen volume on prognosis. We enrolled patients with metastatic PDAC who failed gemcitabine-based therapy and were initiated on NalFL between August 2018 and November 2020.

Semaphorins (SEMAs) are membrane-bound or soluble proteins that participate in organ development and cancer progression, however, the detailed role of SEMAs in carcinogenesis is not fully elucidated yet. Our analysis showed among the differentially expressed SEMAs in colon cancer tissues, patients with higher SEMA4C expression tumors had worse survival. The migration and invasion of the HCT116 and CT26 colon cancer cells were significantly suppressed by SEMA4C neutralizing antibody treatment; while enhanced by ectopic expression of SEMA4C.

, a newly described horsehair worm that parasitizes the millipede, is one of the three described horsehair worm species in Taiwan. It is morphologically similar to Schmidt-Rhaesa, 2010 because of the progressively broadening distribution of bristles concentrated on the male tail lobes, but it is distinguishable from because of the stout bristles on the mid-body. In addition, a vertical white stripe on the anterior ventral side and areoles on the inside wall of the cloacal opening are rarely mentioned in other species.

Pancreatic ductal adenocarcinoma (PDAC) is an aggressive disease, which is characterized by its high invasiveness, rapid progression, and profound resistance to therapy. Gemcitabine is the first-line treatment option for pancreatic cancer patients, but the overall survival is quite low. Therefore, it is an urgent issue to identify new molecules for improved therapies, with better efficacy and less toxicity.

MiR-182 promotes proliferation and invasion and elevates the HIF-1α-VEGF-A axis in breast cancer cells by targeting FBXW7.

The feature of imperfect complementary effect of miRNAs to mRNAs implies that miRNAs may simultaneously target different mRNAs to affect multiple aspects of tumorigenesis. In our previous results, we demonstrated that miR-182 was over-expressed in breast cancer cell lines and clinical tumor tissues and its up-regulation increased tumorigenicity and invasiveness by repressing a tumor suppressor RECK. In this study, we showed that overexpression miR-182 regulated actin distribution and filopodia formation to increase invasiveness of breast cancer cells.

Pyruvate kinase is a key enzyme in the glycolytic pathway that converts phosphoenolpyruvate to pyruvate, and the M2 isoform of pyruvate kinase (PKM2) is associated with cancer. PKM2 has been reported to function independently of its pyruvate kinase activity, which is crucial for cancer cell proliferation. Moreover, there is growing evidence indicating that dimeric PKM2 is released from tumor cells into the circulation of cancer patients.

The reversion-inducing cysteine-rich protein with kazal motif (RECK) is an endogenous matrix metalloproteinase (MMP) inhibitor and a tumor suppressor. Its expression is dramatically down-regulated in human cancers. Our recent results suggest a novel MMP-independent anti-cancer activity of RECK by inhibiting the erbB signaling.

Background: By data mining from published transcriptomic databases, we identified RAP2A as a significantly upregulated gene in nasopharyngeal carcinoma (NPC) tissues. RAP2A, a member of the RAS oncogene family, is involved in the process of GTP binding and GTPase activity. The aim of this study was to evaluate the expression of RAP2A and its prognostic impact in patients with early and locoregionally advanced NPC.

Aims: Urothelial carcinoma (UC) is the most common tumor involving upper urinary tract (UTUC) and urinary bladder (UBUC) whose molecular survival determinants remains obscured. By computerizing a public transcriptomic database of UBUCs (GSE32894), we identified cell division cycle associated 5 (CDCA5) as the most significantly upregulated gene among those associated with G1-S transition of the mitotic cell cycle (GO:0000082). We therefore analyzed the clinicoptaological significance of CDCA5 expression in our well-characterized UC cohort.
