The interaction between aflatoxin and malaria was tested for its usefulness as a model for hepatic tumor induction in rats. Male Buffalo rats which received aflatoxin B1 (AFB1) followed by Plasmodium berghei infection developed more preneoplastic lesions in the liver compared to those given AFB1 alone. No preneoplastic lesions were found in the liver of control and malarial-treated animals. These findings suggest that the malarial parasite facilitates liver tumor development initiated by AFB1 in rats.

Aberrant FGF signaling promotes granule neuron precursor expansion in SHH subgroup infantile medulloblastoma.
Elife

Department of Neurology, Weill Institute for Neuroscience, University of California San Francisco, San Francisco, United States.
Mutations in Sonic Hedgehog (SHH) signaling pathway genes, for example, (SUFU), drive granule neuron precursors (GNP) to form medulloblastomas (MB). However, how different molecular lesions in the Shh pathway drive transformation is frequently unclear, and mutations in the cerebellum seem distinct. In this study, we show that fibroblast growth factor 5 (FGF5) signaling is integral for many infantile MB cases and that expression is uniquely upregulated in infantile MB tumors.

Background/objectives: Gastric intestinal metaplasia (GIM) is considered an irreversible preneoplastic precursor for gastric adenocarcinoma in adults. However, its significance in children and the long-term outcome remain poorly understood.
Methods: All children diagnosed with GIM between 2000 and 2020 were identified at a large tertiary referral centre.
Papillomaviruses and Papillomaviral Disease in Dogs and Cats: A Comprehensive Review.

Faculty of Veterinary Medicine, University of Calgary, Calgary, AB T3R 1J3, Canada.
Papillomaviruses (PVs) frequently infect humans as well as non-human species. While most PV infections are asymptomatic, PVs can also cause hyperplastic papillomas (warts) as well as pre-neoplastic and neoplastic lesions. In this review, the life cycle of PVs is discussed, along with the mechanisms by which PVs cause hyperplastic and neoplastic diseases.

The present investigation explores into the influence of dietary nutrients, particularly alpha-linolenic acid (ALA), a plant-derived omega-3 fatty acid abundant in perilla seed oil (PSO), on the development of colitis-associated colorectal cancer (CRC). The study employs a mouse model to scrutinize the effects of ALA-rich PSO in the context of inflammation-driven CRC. Perilla seeds were subjected to oil extraction, and the nutritional composition of the obtained oil was analysed.

Objective: We aimed to investigate the epidemiology of human papilloma virus (HPV)-related preneoplastic and neoplastic vulvar lesions in a large cohort of women living with HIV (WLWH).
Materials And Methods: We retrospectively selected 1,796 WLWH who had a gynecological examination, cervical cytology, high-risk (HR-) HPV test, vulvoscopy, and colposcopy with targeted biopsies when necessary between 1987 and 2020 at 2 Italian institutions. Univariable and multivariable regression analyses were carried out to test the association of the anamnestic and clinical data with the development of precancerous and cancerous lesions.
