Vav1-dependent Rac1 activation mediates hypoxia-induced gemcitabine resistance in pancreatic ductal adenocarcinoma cells through upregulation of HIF-1α expression.

Hypoxia has been shown to induce gemcitabine (GEM) resistance in pancreatic ductal adenocarcinoma (PDAC) cells, however, the underlying mechanisms remain to be clarified. In the present study, we investigated whether activation of Vav1/Rac1/HIF-1α axis is responsible for hypoxia-induced GEM resistance in PDAC cells. Our results showed that Rac1 activation contributed to hypoxia-induced GEM resistance in PANC-1 cells.

Linc00662 mA promotes the progression and metastasis of pancreatic cancer by activating focal adhesion through the GTF2B-ITGA1-FAK pathway.

Recurrence and metastasis are major factors associated with the poor prognosis of pancreatic cancer (PC). Previous studies have indicated that METTL3-mediated N6-methyladenosine (mA) modification is closely associated with PC progression and prognosis. However, its underlying regulatory mechanisms remain unclear.

ACTR3 promotes cell migration and invasion by inducing epithelial mesenchymal transition in pancreatic ductal adenocarcinoma.

Background: Recurrence and metastasis are the major causes of pancreatic ductal adenocarcinoma (PDAC) mortality after treatment. The underlying molecular mechanism is poorly understood. Actin-related protein 3 (ACTR3) is an important component of the actin-related protein 2/3 complex, which is involved in the regulation of cell motility and epithelial mesenchymal transition (EMT) process.

A Consortium Blockchain-Based Agricultural Machinery Scheduling System.

The introduction of a consortium blockchain-based agricultural machinery scheduling system will help improve the transparency and efficiency of the data flow within the sector. Currently, the traditional agricultural machinery centralized scheduling systems suffer when there is a failure of the single point control system, and it also comes with high cost managing with little transparency, not leaving out the wastage of resources. This paper proposes a consortium blockchain-based agricultural machinery scheduling system for solving the problems of single point of failure, high-cost, low transparency, and waste of resources.

Using Machine Learning Methods to Provision Virtual Sensors in Sensor-Cloud.

The advent of sensor-cloud technology alleviates the limitations of traditional wireless sensor networks (WSNs) in terms of energy, storage, and computing, which has tremendous potential in various agricultural internet of things (IoT) applications. In the sensor-cloud environment, virtual sensor provisioning is an essential task. It chooses physical sensors to create virtual sensors in response to the users' requests.

Dendritic cell vaccine for the effective immunotherapy of breast cancer.

Cancer vaccine is widely considered as a powerful tool in immunotherapy. In particular, the effective antigen processing and presentation natures of dendritic cell (DC) have made it a promising target for the development of therapeutic vaccine for cancer treatment. Here in our study, a versatile cancer cell membrane (CCM) coated calcium carbonate (CC) nanoparticles (MC) that capable of generating in situ tumor-associated antigens (TAAs) for DC vaccination is developed.

Downregulation of SLC5A8 inhibits hepatocellular carcinoma progression through regulation of Wnt/β-catenin signaling.

SLC5A8 has been shown to be associated with a large number of cancer progressions. However, the biological functions of SLC5A8 in hepatocellular carcinoma (HCC) remain largely unclear. Therefore, we performed this research to explore the functions of SLC5A8 in HCC progression.
