A forensic genetic investigation reveals a captive origin for a wild alien population of raccoons in Italy.

Invasive alien species have extensively impacted the ecosystems, where they may affect the native biodiversity. The North American raccoon Procyon lotor is one of the most successful invaders in Europe since its introduction in the early twentieth century. In Italy, a wild population was first established in the North at the beginning of the 2000s following a local introduction event.

Decoding the role of microRNA dysregulation in the interplay of pancreatic cancer and type 2 diabetes.

This study examines the complex relationship between pancreatic cancer (PC) and type 2 diabetes (T2D) by focusing on the role of microRNAs (miRNAs). miRNAs are small non-coding RNAs that regulate gene expression and have been implicated in many diseases, including T2D and cancer. To begin, we conducted a literature review to identify miRNAs associated with the PC-T2D link.

How to Choose? Comparing Different Methods to Count Wolf Packs in a Protected Area of the Northern Apennines.

Despite a natural rewilding process that caused wolf populations in Europe to increase and expand in the last years, human-wolf conflicts still persist, threatening the long-term wolf presence in both anthropic and natural areas. Conservation management strategies should be carefully designed on updated population data and planned on a wide scale. Unfortunately, reliable ecological data are difficult and expensive to obtain and often hardly comparable through time or among different areas, especially because of different sampling designs.

Integrative transcriptomic analysis of pancreatic islets from patients with prediabetes/type 2 diabetes.

Aim: To identify new transcriptomic alterations in pancreatic islets associated with metabolic dysfunctions in people with prediabetes (PD)/type 2 diabetes (T2D).

Materials And Methods: We collected information from public data repositories T2D related microarray datasets from pancreatic islets. We identified Differential Expressed Genes (DEGs) in non-diabetic (ND) vs people with T2D in each study.

Ephrin-B1 Is a Novel Biomarker of Bladder Cancer Aggressiveness. Studies in Murine Models and in Human Samples.

Bladder cancer (BC) is the ninth most common cancer worldwide, but molecular changes are still under study. During tumor progression, Epithelial cadherin (E-cadherin) expression is altered and β-catenin may be translocated to the nucleus, where it acts as co-transcription factor of tumor invasion associated genes. This investigation further characterizes E-cadherin and β-catenin associated changes in BC, by combining bioinformatics, an experimental murine cell model (MB49/MB49-I) and human BC samples.

Increasing DNA Isolation Performance from Blood Cells Using a Modified Commercial Low-Cost Reagent.

Background: Genomic studies facilitate comprehension of the pathophysiology, diagnosis, and treatment of chronic diseases. Such studies require sufficient and good quality DNA isolated from a large number of blood samples. This study attempts to obtain a high-quality genomic DNA isolated from a large number of blood samples using a simple and cheap method.

Effects of islet neogenesis associated protein depend on vascular endothelial growth factor gene expression modulated by hypoxia-inducible factor 1-alpha.

Background: Pharmacology has provided efficient tools to improve insulin effect/secretion but the decrease in β-cell mass remains elusive. INGAP-PP could provide a therapeutic alternative to meet that challenge.

Aim: To further understand the mechanism that links INGAP-PP effects upon β-cell mass and function with islet angiogenesis.

Identification of a Novel Human E-Cadherin Splice Variant and Assessment of Its Effects Upon EMT-Related Events.

Epithelial Cadherin (E-cadherin) is involved in calcium-dependent cell-cell adhesion and signal transduction. The E-cadherin decrease/loss is a hallmark of Epithelial to Mesenchymal Transition (EMT), a key event in tumor progression. The underlying molecular mechanisms that trigger E-cadherin loss and consequent EMT have not been completely elucidated.

CDH1/E-cadherin and solid tumors. An updated gene-disease association analysis using bioinformatics tools.

Cancer is a group of diseases that causes millions of deaths worldwide. Among cancers, Solid Tumors (ST) stand-out due to their high incidence and mortality rates. Disruption of cell-cell adhesion is highly relevant during tumor progression.

Streptonigrin induces delayed chromosomal instability involving interstitial telomeric sequences in Chinese hamster ovary cells.

We analyzed the induction of chromosomal aberrations in Chinese hamster ovary (CHO) cells exposed to the radiomimetic compound streptonigrin (SN), in order to determine whether interstitial telomeric sequences (ITSs) are involved in the long-term clastogenic effect of this antibiotic. CHO cells were treated with a single concentration of SN (100ng/ml), and the frequency of unstable chromosomal aberrations was determined at three times after treatment (18h, and 6 and 15 days) by using PNA-FISH with a pan-telomeric probe. Cytogenetic analysis revealed a higher frequency of aberrations at 18h and 6 days after treatment in SN-exposed cultures vs.
