We investigated mechanisms of resistance of liver tumors in mice to infiltrating T cells.Mice were given hydrodynamic tail vein injections of clustered regularly interspaced short palindromic repeats-Cas9 (CRISPR-Cas9) and transposon vectors to disrupt Trp53 and overexpress C-Myc (Trp53KO/C-MycOE mice). (stanford.edu)
tumors were analyzed by mass cytometry using markers to detect T cells and other lymphocytes. (stanford.edu)
Tumors from mice given anti-PD1 had larger numbers of memory CD8+ T cells (CD44+CD62L-KLRG1int) and T cells that expressed PD1, lymphocyte activating 3 (LAG3), and TIGIT compared with mice not given the antibody. (stanford.edu)

Head and neck squamous cell carcinoma (HNSCC) is a type of tumor that originates from the squamous epithelium of the head and neck areas, including the mucous membranes of the lips, tongue, pharynx, larynx, and others ( 1 ). (frontiersin.org)

Altogether, our results suggest that MCL1 is a key molecule deciding over the fate of PCa cells upon inactivation of androgen receptor signaling. (oncotarget.com)

Renal cell carcinoma (RCC) incidence has increased over the past two decades. (hindawi.com)
Renal cell carcinoma (RCC) accounts for approximately 3% of human malignancies, and its incidence appears to be increasing globally [ 1 ]. (hindawi.com)

Epidermodysplasia verruciformis (EV) is a rare, inherited disorder that predisposes patients to widespread human papillomavirus (HPV) infection and cutaneous squamous cell carcinomas . (medscape.com)

Increases in the amount of PAPP-A mRNA in granulosa cells during follicular development occurs in some but not all species, indicating that other proteases or protease inhibitors may be involved in IGFBP degradation. (bioone.org)

The TP53 gene is also capable of stimulating apoptosis of cells containing damaged DNA. (medscape.com)

[1] pl. mitochondria ) is an organelle found in the cells of most eukaryotes , such as animals , plants and fungi . (wikipedia.org)
Mitochondria have a double membrane structure and use aerobic respiration to generate adenosine triphosphate (ATP), which is used throughout the cell as a source of chemical energy . (wikipedia.org)
Inside the mitochondria, pyruvate is completely oxidized through the TCA cycle, feeding reductive equivalents to the electron transport chain. (hindawi.com)

Hematopoietic stem cells, which can produce several different types of blood cells, are prime examples of multipotency. (papersowl.com)

A tumour - also known as a neoplasm - is a collection of cells which have grown into a defined shape. (biotopics.co.uk)
In 1995, Campbell and his scientific team used cells grown and differentiated in a laboratory to clone sheep for the first time. (asu.edu)

In this paper, we describe the metabolic changes as well as the mechanisms of resistance to apoptosis occurring in cancer cells and cancer stem cells, underlying the connection between these two processes. (hindawi.com)

Hayflick, L. The limited in vitro lifetime of human diploid cell strains. (nature.com)

Multiple different methods have been demonstrated to selectively kill senescent cells in mice, including the genetic engineering approach used a few years ago and the various senolytic drug candidates discovered more recently. (fightaging.org)
Why is the destruction of senescent cells an important goal? (fightaging.org)
Evolution likes reuse, and senescent cells are also transiently involved in wound healing and structural control over embryonic development . (fightaging.org)
Nonetheless, having too many senescent cells is a bad thing, and that is exactly what happens with advancing age: senescent cells that evade destruction linger indefinitely, and their numbers grow over time, especially once the immune system starts to decline in old age . (fightaging.org)
Periodic removal of senescent cells would solve all of these problems. (fightaging.org)
It is, however, quite possible for a therapy to be too good at killing senescent cells. (fightaging.org)
Approaches that could be this efficient in theory will be diluted or otherwise limited and delivered over a number of spaced treatments, producing a steady or stepped destruction of senescent cells at a safe pace. (fightaging.org)

In 1868, Paul Langerhans discovered the epidermal dendritic cells that now bear his name. (medscape.com)

This is probably a defense against cancer, removing from play those cells most likely to become cancerous. (fightaging.org)
Malignant tumours are cancerous growths and because their cell division is not subject to normal control they may grow quite fast and can sometimes spread to other parts of the body. (biotopics.co.uk)

Lymphoid and myeloid stem cells are ideal examples of oligopotent stem cells. (papersowl.com)

The working group of the Histiocyte Society divided histocytic disorders into three groups: (1) dendritic cell histiocytosis, (2) macrophage-related disorders, and (3) malignant histiocytosis. (medscape.com)

Following a certain cell type-dependent number of mitotic divisions, most cells enter a phase of replicative senescence [1]. (biopaqc.com)

The elimination of P-glycoprotein over-expressing cancer cells by antimicrobial cationic peptide NK-2: the unique way of multi-drug resistance modulation. (ac.rs)

A senescent cell stops replicating and secretes signals that both adjust the behavior of surrounding cells, making them more likely to become senescent, and make the senescent cell itself a target for destruction by the immune system . (fightaging.org)
Signals to trigger apoptosis may come from within the cell or from outside, by stimulating suicide receptors in the cell's external membrane. (agemed.org)

In this review, we consider what is currently known of the genetic landscape of the commonest subtypes of renal cell cancer (RCC). (springer.com)
When the genetic information containing the "blueprint" for these substances is disrupted, cell homeostasis is disrupted, resulting in a wide-range of immediate and/or delayed toxicological effects. (cdc.gov)

This reverses its normal inhibitory action, resulting in the rapid and uncontrollable cell division which is the hallmark of cancer. (biotopics.co.uk)
