The concerted metabolic reprogramming across cancer and normal cellular compartments of the tumor microenvironment can favor tumorigenesis by increasing the survival and proliferating capacities of transformed cells. p62 has emerged as a critical signaling adaptor, beyond its role in autophagy, by playing an intricate context-dependent role in metabolic reprogramming of the cell types of the tumor and stroma, which shapes the tumor microenvironment to control tumor progression. Focusing on metabolic adaptations, we review the cellular processes upstream and downstream of p62 that regulate how distinct cell types adapt to the challenging and evolving environmental conditions during tumor initiation and progression. In addition, we describe partners of p62 that, in a collaborative or independent manner, can also rewire cell metabolism. Finally, we discuss the potential therapeutic implications of targeting p62 in cancer, considering its multifaceted roles in diverse cell types of the tumor microenvironment.

Metabolic reprogramming has now been accepted as a hallmark of cancer. Compared to normal cells, cancer cells exhibit different metabolic features, including increased glucose uptake, aerobic glycolys...
Nutrient-sensing mechanisms ensure that cellular activities are coordinated with nutrient availability. Recent work has established links between metabolite pools and protein post-translational modifi...
While metabolic reprogramming of cancer cells has long been considered from the standpoint of how and why cancer cells preferentially utilize glucose via aerobic glycolysis, the so-called Warburg Effe...
Metabolic reprogramming represents an important hallmark of cancer cells. Besides de novo fatty acid synthesis, it is now clear that cancer cells can acquire fatty acids (FA) from tumor-surrounding ad...
Cancer cells undergo metabolic reprogramming such as enhanced aerobic glycolysis, mutations in the tricarboxylic acid cycle enzymes, and upregulation of de novo lipid synthesis and glutaminolysis. The...
This study investigates the reprogramming of myeloid cells in patients with thyroid carcinoma. The investigators hypothesize that tumor-derived factors change the function of myeloid cells...
Lung cancer is the most common cancer in men and the fourth most common cancer in women worldwide. Until today no effective method permits the early detection of lung cancer. Consequently,...
Genomic alterations have long been recognized as an important factor in tumor formation and drive tumor cell growth. However, the degree of genomic mutation (tumor mutation load, TMB) vari...
Diffuse glioms are primary brain tumors characterized by infiltrative growth and high heterogeneity, which render the disease mostly incurable. Advances in genetic analysis revealed that m...
Over the last 10 years, technological advances in molecular biology enabled a more accurate genomic characterization of tumors. For each tumor location, this led to the identification of s...
Procedures used for the induction of CELLULAR REPROGRAMMING to change the terminal phenotype of a cell, such as the generation of INDUCED PLURIPOTENT STEM CELLS from differentiated adult cells by the forced expression of specific genes.
The milieu surrounding neoplasms consisting of cells, vessels, soluble factors, and molecules, that can influence and be influenced by, the neoplasm's growth.
The process that reverts CELL NUCLEI of fully differentiated somatic cells to a pluripotent or totipotent state. This process can be achieved to a certain extent by NUCLEAR TRANSFER TECHNIQUES, such as fusing somatic cell nuclei with enucleated pluripotent embryonic stem cells or enucleated totipotent oocytes. GENE EXPRESSION PROFILING of the fused hybrid cells is used to determine the degree of reprogramming. Dramatic results of nuclear reprogramming include the generation of cloned mammals, such as Dolly the sheep in 1997.
Subpopulation of heterogeneous fibroblasts within the TUMOR MICROENVIRONMENT that support NEOPLASTIC CELL TRANSFORMATION and NEOPLASTIC PROCESSES.
Disorders that include recurrent, intense sexually arousing fantasies, sexual urges, or behaviors generally involving nonhuman objects, suffering of oneself or partners, or children or other nonconsenting partners. (from DSM-IV, 1994)
Cancer is not just one disease but many diseases. There are more than 100 different types of cancer. Most cancers are named for the organ or type of cell in which they start - for example, cancer that begins in the colon is called colon cancer; cancer th...
