Summary: In this study, OSBP2 was found to be highly expressed in PDAC and its upregulation promoted the progression of PDAC, including increased cell migration, invasion, proliferation, chemotherapy resistance, and decreased apoptosis. Furthermore, overexpression of OSBP2 resulted in downregulation of the cell adhesion molecule E-cadherin and upregulation of other transcription factors. Therefore, OSBP2 may serve as a potential diagnostic and therapeutic target for PDAC.

Summary: The study found that miR-33a-5p expression is significantly decreased in PDAC tissues and cell lines, and its downregulation is significantly associated with TNM staging and lymph node metastasis. Overexpression of miR-33a-5p inhibits cell proliferation, migration, and invasion in SW1990 and PANC-1 cells, while knockdown of miR-33a-5p promotes these processes in BxPC-3 and ASPC-1 cells. Additionally, RAP2A was identified as a direct target of miR-33a-5p in PDAC cells, and its overexpression reversed the suppressive effects of miR-33a-5p in SW1990 and PANC-1 cells.

Summary: Pancreatic ductal adenocarcinoma (PDAC) is a highly aggressive tumor with a poor prognosis. S100A10, a member of the S100 protein family, has been found to be up-regulated in PDAC and associated with a worse prognosis. This study suggests that S100A10 promotes PDAC cell proliferation, migration, and adhesion through the activation of the JNK/LAMB3-LAMC2 axis, making it a potential therapeutic target for PDAC patients.

Summary: This study explores the relationship between the oral and tumor microbiomes in patients with pancreatic ductal adenocarcinoma (PDAC). It reveals a high prevalence and relative abundance of oral bacteria, particularly Veillonella and Streptococcus, in tumor tissue. The most prevalent and abundant taxon, Veillonella atypica, was cultured from patient saliva, sequenced and annotated, identifying genes that may contribute to tumorigenesis. The sequence similarity between patient matched saliva and tumor tissue suggests that the microbiota in PDAC tumors may originate from the mouth. These findings may have clinical implications for the care and treatment of PDAC patients.

Summary: This study investigated the function and mechanism of ZSWIM1 in lung adenocarcinoma. ZSWIM1 was found to be upregulated in lung adenocarcinoma and correlated with poor prognosis. It promoted cancer cell proliferation, migration, invasion, and epithelial-to-mesenchymal transition. The protein interactome of ZSWIM1 was identified, and its interaction with STK38 was verified. ZSWIM1 antagonized the function of STK38 and activated the MEKK2/ERK1/2 pathway. Overall, ZSWIM1 acts as an oncogene in lung adenocarcinoma and its effects are mediated through the STK38/MEKK2/ERK1/2 axis.

Summary: PKN2 plays a critical role in the differentiation of pancreatic stellate cells into myofibroblast-like cancer-associated fibroblasts. Loss of PKN2 leads to reduced proliferation and contractility of pancreatic stellate cells, as well as a switch from myofibroblast to inflammatory cancer-associated fibroblast phenotype. Furthermore, deletion of PKN2 promotes invasive cancer cell outgrowth and induces more locally invasive pancreatic tumors. The absence of PKN2 in the pancreatic stroma predicts poor outcome in pancreatic and other solid human cancers.

Summary: AHNAK2 is a newly discovered protein with a strong association with oncogenesis in various epithelial cancers. It has a tripartite structure and is believed to be involved in the formation of large multi-protein complexes. High expression of AHNAK2 is found in several cancers, including clear cell renal carcinoma and pancreatic ductal adenocarcinoma, and is associated with poor prognosis. Limited research has been conducted on the function and relation of AHNAK2 with cancer, but early studies suggest its potential as a future biomarker and therapeutic target.

Summary: The dynamical process of cell division that maintains homeostasis in the human body cannot be observed directly. Instead, it is measured through somatic genetic or epigenetic mutations in tissues. Mathematical analysis of somatic clone sizes provides quantitative information on cell birth, death, and replacement rates. This review explores the use of different somatic mutation types for lineage tracing in human tissues, introduces mathematical concepts for inferring dynamic information from clone size data, and discusses the implications of this approach for understanding homeostasis and cancer development.

Summary: The establishment of patient-derived pancreatic cancer organoid culture has provided an important tool to study genomic heterogeneity and stability in cancer cells. Research has shown the presence of clonal populations with similar copy number profiles in pancreatic cancer organoids, and the proportion of these clones changes with extended culture, indicating the growth advantage of certain clones. However, sub-clonal genomic heterogeneity is also observed within each clonal population, suggesting the genomic instability of pancreatic cancer cells. Additionally, gene expression regulation is influenced by copy number alterations.

Summary: Patients with estrogen receptor (ER)-positive breast cancer are at risk of metastatic relapse due to dormant disseminated tumor cells (DTCs) reawakening at secondary sites. Aging or fibrotic microenvironment promotes DTC proliferation and upregulates tumor cell Pdgfc expression, stimulating further stromal activation. This study suggests targeting PDGF-C signaling could limit metastatic relapse in ER+ breast cancer.
