Cancer is a disease that affects the majority of metazoan species and, before directly causing host death, is likely to influence the competitive abilities of individuals, their susceptibility to pathogens, their vulnerability to predators, and their ability to disperse. Despite the potential importance of these ecological impacts, cancer is rarely incorporated into model ecosystems. We describe here the diversity of ways in which oncogenic phenomena, from precancerous lesions to generalized metastatic cancers, may affect ecological processes that govern biotic interactions. We argue that oncogenic phenomena, despite their complexity, can have significant and sometimes predictable ecological consequences. Our aim is to provide a new perspective on the ecological and evolutionary significance of cancer in wildlife, and to stimulate research on this topic.

Persistence is a strategy used by many viruses to evade eradication by the immune system, ensuring their permanence and transmission within the host and optimizing viral fitness. During persistence, viruses can trigger various phenomena, including target organ damage, mainly due to an inflammatory state induced by infection, as well as cell proliferation and/or immortalization. In addition to immune evasion and chronic inflammation, factors contributing to viral persistence include low-level viral replication, the accumulation of viral mutants, and, most importantly, maintenance of the viral genome and reliance on viral oncoprotein production.

Article Synopsis
- The study investigates how high glucose levels in diabetes lead to kidney cell damage through the activation of a signaling pathway involving DJ-1 and PTEN.
- DJ-1 is found to be upregulated in kidney cells under high glucose conditions, which triggers the Akt/mTORC1 signaling pathway, resulting in cell growth and fibrosis.
- The research indicates that inhibiting DJ-1 can prevent glucose-induced cell growth and damage, while overexpressing DJ-1 replicates the harmful effects, highlighting its role in renal injury related to diabetes.

Long-term cultured calli may experience a biosynthetic shift due to the IAA-dependent expression of the rolA gene, which also affects ROS metabolism. The "hairy root" syndrome is caused by the root-inducing Ri-plasmid of Rhizobium rhizogenes, also known as Agrobacterium rhizogenes. The Ri-plasmid contains genes known as rol genes or root oncogenic loci, which promote root development.

In cancer research, the term epigenetics was used in the 1970s in its modern sense encompassing non-genetic events modifying the chromatin state, mainly to oppose the emerging oncogene paradigm. However, starting from the establishment of this prominent concept, the importance of these epigenetic phenomena in cancer rarely led to questioning the causal role of genetic alterations. Only in the last 10 years, the accumulation of problematic data, better experimental technologies, and some ambitious models pushed the idea that epigenetics could be at least as important as genetics in early oncogenesis.

Article Synopsis
- Glioma is the most prevalent primary brain tumor, known for its aggressive nature and poor patient outcomes, leading to a need for better prognostic tools.
- Researchers employed machine learning and multi-omics approaches to identify key genes such as CENPA, allowing glioma to be classified into three distinct subtypes based on 14 cancer functional states (CFS).
- CENPA was found to have high expression levels and significant roles in glioma cell functions, influencing tumor behavior and outcomes, while its regulation by EZH2 and interaction with the Wnt pathway were also highlighted.
