The efficacy of combined radiation and fluorouracil as adjuvant therapy for pancreatic cancer is suggested by a prospective randomized study conducted by the Gastrointestinal Tumor Study Group (GITSG). Twenty-two patients randomized to no adjuvant treatment and 21 to combined therapy were analyzed. Neither life-threatening toxic reaction nor death due to toxic effect was encountered. The study was terminated prematurely because of an unacceptably low rate of accrual combined with the observation of increasingly large survival differences between the study arms. Median survival for the treatment group (20 months) was significantly longer than that observed for the control group (11 months). Four patients, three in the treated and one in the control group, have survived five years or longer following surgery. The extent of the tumor and initial performance status were significantly and independently related to survival.

Background: Diabetes mellitus (DM), a chronic metabolic disease, is characterized by long-term hyperglycemia resulting from the defect of insulin production and insulin resistance. The damage and dysfunction of pancreatic β-cells is a main link in DM development.
Methods: In this work, pancreatic β-cell line INS-1E cells were exposed to 30 mM glucose for 48 h to construct an in vitro DM model.

Macrophages play a central role in antitumor immunity, making them an attractive target for gene therapy strategies. However, macrophages are difficult to transfect because of nucleic acid sensors that can trigger the degradation of foreign plasmid DNA. Here, we developed a macrophage-specific editing (MAGE) system by which compact plasmid DNA encoding a CasRx editor can be delivered to macrophages by a poly(β-amino ester) (PBAE) carrier to bypass the DNA sensor and enable RNA editing in vitro and in vivo.

The prevalence of childhood obesity is increasing worldwide, along with the associated common comorbidities of type 2 diabetes and cardiovascular disease in later life. Motivated by evidence for a strong genetic component, our prior genome-wide association study (GWAS) efforts for childhood obesity revealed 19 independent signals for the trait; however, the mechanism of action of these loci remains to be elucidated. To molecularly characterize these childhood obesity loci, we sought to determine the underlying causal variants and the corresponding effector genes within diverse cellular contexts.

Grade progression of well differentiated pancreatic neuroendocrine tumors (panNETs) can occur over time, with G1/2 to G3 the most clinically relevant form. Here we conducted a retrospective cohort study of 66 patients with initially G1/2 panNET (median initial Ki67, 4.6%).
