Hypoxia-Induced Signaling in Gut and Liver Pathobiology
Annu Rev Pathol. 2023 Oct 13. doi: 10.1146/annurev-pathmechdis-051122-094743. Online ahead of print.ABSTRACTOxygen (O2) is essential for cellular metabolism and biochemical reactions. When the demand for O2 exceeds the supply, hypoxia occurs. Hypoxia-inducible factors (HIFs) are essential to activate adaptive and survival responses following hypoxic stress. In the gut (intestines) and liver, oxygen gradients or physiologic hypoxia are necessary to maintain normal homeostasis. While physiologic hypoxia is beneficial and aids in normal functions, pathological hypoxia is harmful as it exacerbates inflammatory responses and ti...

Role of the Microenvironment in Glioma Pathogenesis
Annu Rev Pathol. 2023 Oct 13. doi: 10.1146/annurev-pathmechdis-051122-110348. Online ahead of print.ABSTRACTGliomas are a diverse group of primary central nervous system tumors that affect both children and adults. Recent studies have revealed a dynamic cross talk that occurs between glioma cells and components of their microenvironment, including neurons, astrocytes, immune cells, and the extracellular matrix. This cross talk regulates fundamental aspects of glioma development and growth. In this review, we discuss recent discoveries about the impact of these interactions on gliomas and highlight how tumor cells actively ...

Cancer as a Disease of Development Gone Awry
Annu Rev Pathol. 2023 Oct 13. doi: 10.1146/annurev-pathmechdis-031621-025610. Online ahead of print.ABSTRACTIn the 160 years since Rudolf Virchow first postulated that neoplasia arises by the same law that regulated the embryonic development, scientists have come to recognize the striking overlap between the molecular and cellular programs used by cancers and embryos. Advances in cancer biology and molecular techniques have further highlighted the similarities between carcinogenesis and embryogenesis, where cellular growth, differentiation, motility, and intercellular cross talk are mediated by common drivers and regulator...

Comparative Pathogenesis of Severe Acute Respiratory Syndrome Coronaviruses
Annu Rev Pathol. 2023 Oct 13. doi: 10.1146/annurev-pathol-052620-121224. Online ahead of print.ABSTRACTOver the last two decades the world has witnessed the global spread of two genetically related highly pathogenic coronaviruses, severe acute respiratory syndrome coronavirus (SARS-CoV) and SARS-CoV-2. However, the impact of these outbreaks differed significantly with respect to the hospitalizations and fatalities seen worldwide. While many studies have been performed recently on SARS-CoV-2, a comparative pathogenesis analysis with SARS-CoV may further provide critical insights into the mechanisms of disease that drive cor...

Genome Instability and DNA Repair in Somatic and Reproductive Aging
Annu Rev Pathol. 2023 Oct 13. doi: 10.1146/annurev-pathmechdis-051122-093128. Online ahead of print.ABSTRACTGenetic material is constantly subjected to genotoxic insults and is critically dependent on DNA repair. Genome maintenance mechanisms differ in somatic and germ cells as the soma only requires maintenance during an individual's lifespan, while the germline indefinitely perpetuates its genetic information. DNA lesions are recognized and repaired by mechanistically highly diverse repair machineries. The DNA damage response impinges on a vast array of homeostatic processes and can ultimately result in cell fate changes...

Clonal Hematopoiesis, Inflammation, and Hematologic Malignancy
Annu Rev Pathol. 2023 Oct 13. doi: 10.1146/annurev-pathmechdis-051222-122724. Online ahead of print.ABSTRACTSomatic or acquired mutations are postzygotic genetic variations that can occur within any tissue. These mutations accumulate during aging and have classically been linked to malignant processes. Tremendous advancements over the past years have led to a deeper understanding of the role of somatic mutations in benign and malignant age-related diseases. Here, we review the somatic mutations that accumulate in the blood and their connection to disease states, with a particular focus on inflammatory diseases and myelodys...

Within-Host Evolution of Bacterial Pathogens in Acute and Chronic Infection
Annu Rev Pathol. 2023 Oct 13. doi: 10.1146/annurev-pathmechdis-051122-111408. Online ahead of print.ABSTRACTBacterial pathogens undergo remarkable adaptive change in response to the selective forces they encounter during host colonization and infection. Studies performed over the past few decades have demonstrated that many general evolutionary processes can be discerned during the course of host adaptation, including genetic diversification of lineages, clonal succession events, convergent evolution, and balanced fitness trade-offs. In some cases, elevated mutation rates resulting from mismatch repair or proofreading defi...

Neurodegenerative Disease Tauopathies
Annu Rev Pathol. 2023 Oct 13. doi: 10.1146/annurev-pathmechdis-051222-120750. Online ahead of print.ABSTRACTTauopathies are a diverse group of progressive and fatal neurodegenerative diseases characterized by aberrant tau inclusions in the central nervous system. Tau protein forms pathologic fibrillar aggregates that are typically closely associated with neuronal cell death, leading to varied clinical phenotypes including dementia, movement disorders, and motor neuron disease. In this review, we describe the clinicopathologic features of tauopathies and highlight recent advances in understanding the mechanisms that lead to...

Epigenomic Characterization of Lymphoid Neoplasms
Annu Rev Pathol. 2023 Oct 13. doi: 10.1146/annurev-pathmechdis-051122-100856. Online ahead of print.ABSTRACTLymphoid neoplasms represent a heterogenous group of disease entities and subtypes with markedly different molecular and clinical features. Beyond genetic alterations, lymphoid tumors also show widespread epigenomic changes. These severely affect the levels and distribution of DNA methylation, histone modifications, chromatin accessibility, and three-dimensional genome interactions. DNA methylation stands out as tracer of cell identity and memory, as B cell neoplasms show epigenetic imprints of their cellular origin ...
