Background: Acute myeloid leukemia (AML) is a type of blood cancer involving numerous aberrant genes and microRNAs. MiRNAs are non-coding sequences that have been proven to be players in the biological processes of various cancers. The present study is designed to illustrate the relationship between miR-155, KRAS, and CREB.
Methods: This case-control study was conducted on 21 patients with AML and 9 healthy individuals. The expressions of miR-155, KRAS, and CREB were measured using RT-PCR. Demographic data were extracted from the documents of individuals. SPSS and GraphPad Prism software were used to analyze the data.
Results: The expression of miR-155 in patients with AML was 35 times higher than in the control group (p < 0.0001). Also, CREB fold change increased by 1.92-fold in patients compared to the controls (p = 0.034), but no difference in KRAS was observed between the control and AML groups (p > 0.05). There was no change in miR-155, CREB, and KRAS expression based on gender, age, and blast percentage (p > 0.5). Nevertheless, there was a direct correlation between CREB and KRAS expressions (p = 0.0002). Our result showed that overexpression of CREB and KRAS would cause an increase in white blood cells (WBCs) (p = 0.001, 0.045 respectively), but there was no correlation between miR-155 with WBCs (p > 0.5).
Conclusions: Our study revealed that miR-155 and CREB had overexpression compared to the control group.

Article Synopsis
- A study explored the characteristics and outcomes of childhood acute lymphoblastic leukemia (ALL) cases with specific gene mutations, involving 14 patients over 7 years.
- The majority of affected children were girls, with a median age of just over 4 years, and they exhibited a high rate of complete remission (79%) after initial treatment but a notable recurrence rate of 21%.
- Despite challenges, many children achieved long-term survival, and the overall 5-year survival rate for the group was an encouraging 92%.
Redox signaling in the pancreas in health and disease.
Physiol Rev

Department of Physiology, Faculty of Pharmacy, University of Valencia, Valencia, Spain.
This review addresses oxidative stress and redox signaling in the pancreas under healthy physiological conditions as well as in acute pancreatitis, chronic pancreatitis, pancreatic cancer, and diabetes. Physiological redox homeodynamics is maintained mainly by NRF2/KEAP1, NF-κB, protein tyrosine phosphatases, peroxisome proliferator-activated receptor-γ coactivator 1α (PGC1α), and normal autophagy. Depletion of reduced glutathione (GSH) in the pancreas is a hallmark of acute pancreatitis and is initially accompanied by disulfide stress, which is characterized by protein cysteinylation without increased glutathione oxidation.

Background: Olanzapine (OLZ) reverses chronic stress-induced anxiety. Chronic stress promotes cancer development via abnormal neuro-endocrine activation. However, how intervention of brain-body interaction reverses chronic stress-induced tumorigenesis remains elusive.

Background And Aims: induction of alcoholic chronic pancreatitis (ACP) causes significant acinar damage, increased fibroinflammatory response, and heightened activation of cyclic response element binding protein 1 (CREB) when compared with alcohol (A) or chronic pancreatitis (CP) mediated pancreatic damage. However, the study elucidating the cooperative interaction between CREB and the oncogenic (*) in promoting pancreatic cancer progression with ACP remains unexplored.
Methods: Experimental ACP induction was established in multiple mouse models, followed by euthanization of the animals at various time intervals during the recovery periods.
