Pancreatic ductal adenocarcinoma (PDAC) is considered one most aggressive and lethal cancer types worldwide. While its underlying mechanisms are still poorly understood. CircRNAs play essential roles in various biological progression, including PDAC.

Some individuals develop prediabetes and/or diabetes following acute pancreatitis (AP). AP-induced beta-cell injury and the limited regenerative capacity of beta cells might account for pancreatic endocrine insufficiency. Previously, we found that only a few pancreatic cytokeratin 5 positive (Krt5) cells differentiated into beta cells in the murine AP model, which was insufficient to maintain glucose homeostasis.

Aim: Given the fact that tumor-associated macrophage-derived extracellular vesicles (EVs) are attributable to tumor aggressiveness, this research intends to decode the mechanism of M2 macrophage-derived EVs in the differentiation and activities of pancreatic cancer (PaCa) stem cells via delivering microRNA (miR)-21-5p.

Methods: Polarized M2 macrophages were induced, from which EVs were collected and identified. miR-21-5p expression in M2 macrophage-derived EVs was tested.

Background: Pancreatic cancer (PC), characterized with high growth rate and metastatic rate. It's urgently necessary to explore new mechanism of PC. Circular RNA/miRNA/mRNA network was widely reported to participate in the cancer progression.

Background: While CAR-T therapy has successfully treated haematological malignancies, it has proved sub-optimal for solid tumours. The main limitation is the inability of CAR-T cells to infiltrate and then proliferate within tumours.

Method: We co-expressed IL-7 and PH20, a type of hyaluronidase, with CAR targeting GPC3 (G3CAR-7 × 20).

Objective: Diabetes is common in COVID-19 patients and associated with unfavorable outcomes. We aimed to describe the characteristics and outcomes and to analyze the risk factors for in-hospital mortality of COVID-19 patients with diabetes.

Research Design And Methods: This two-center retrospective study was performed at two tertiary hospitals in Wuhan, China.

For colorectal cancer (CRC) patients, local and systemic inflammatory responses have been extensively reported to closely associate with patient survival. However, the specific signaling pathways responsible for carcinogenic responses are unclear. Phosphatase and tensin homolog deleted on chromosome 10 (PTEN) is a negative regulator of PI3K/AKT pathway that is gradually inactivated in cancers through mutation, loss of heterozygosity and others epigenetic mechanisms.

Clinical studies have revealed that some patients will develop glucose tolerance dysfunction after recovering from acute pancreatitis (AP), which indicated the importance of investigating the potential therapies for restoration of islet β cell function. Cytokeratin 5 (Krt5)-positive cells are considered to function as stem or progenitor cells in the regeneration of lung and salivary gland following injury. In the present study, AP was induced by six hourly intraperitoneal injections of 100 μg/kg cerulein for 4 consecutive days in adult mice, in order to determine the role of Krt5-positive cells in pancreatic regeneration, especially in the restoration of β cell function and the underlying mechanisms.

Objectives: The aim of our present study was to investigate the efficacy of poly(adenosine diphosphate-ribose) polymerase (PARP) inhibition in the development of acute kidney injury in an experimental model of severe acute pancreatitis induced by retrograde infusion of sodium taurocholate into the bile-pancreatic duct.

Methods: Severity of pancreatitis was evaluated by serum amylase, lipase, tumor necrosis factor α, interleukin-1β, interleukin-6, and histological grading. The following markers of renal dysfunction and injury were measured: serum creatinine level, urea nitrogen level, myeloperoxidase activity, and histology.
