Inhibition of metabotropic glutamate receptor III facilitates sensitization to alkylating chemotherapeutics in glioblastoma

open access: yesCell Death and Disease, 2021
Glioblastoma (GBM), the most malignant tumor of the central nervous system, is marked by its dynamic response to microenvironmental niches. In particular, this cellular plasticity contributes to the development of an immediate resistance during tumor ...

Identification of the PA1113 Gene Product as an ABC Transporter Involved in the Uptake of Carbenicillin in Pseudomonas aeruginosa PAO1

open access: yesAntibiotics, 2020
The resistance of Pseudomonas aeruginosa to antibiotics is multi factorial and complex. Whereas efflux pumps such as MexAB-OprM have been thought to predominate, here we show that a novel ATP Binding Cassette (ABC) transporter that mediates influx of ...

Role of mTOR signaling in tumor microenvironment. An overview [PDF]

open access: yes, 2018
The mammalian target of rapamycin (mTOR) pathway regulates major processes by integrating a variety of exogenous cues, including diverse environmental inputs in the tumor microenvironment (TME).

Pancreatic cancer microenvironment [PDF]

open access: yesInternational Journal of Cancer, 2007
AbstractPancreatic ductal adenocarcinoma remains an extremely aggressive malignancy that is virtually therapy‐resistant and has therefore one of the worst prognoses of all human cancers. The focus of research, which had been placed mostly on genetic and epigenetic alterations of the cancer cells themselves, has shifted gradually towards the ...

Metabolism within the tumor microenvironment and its implication on cancer progression: an ongoing therapeutic target [PDF]

open access: yes, 2018
Since reprogramming energy metabolism is considered a new hallmark of cancer, tumor metabolism is again in the spotlight of cancer research. Many studies have been carried out and many possible therapies have been developed in the last years.

Plastic hepatocyte states limit liver cancer development

open access: yesNature Communications
The liver has remarkable regenerative capacity owing to the boundless proliferative potential of hepatocytes. During liver injury, sustained regeneration must be balanced by mechanisms limiting overgrowth and tumorigenesis.

The tumour microenvironment links complement system dysregulation and hypoxic signalling. [PDF]

open access: yes, 2018
The complement system is an innate immune pathway typically thought of as part of the first line of defence against "non-self" species. In the context of cancer, complement has been described to have an active role in facilitating cancer-associated ...

Frequency over function : raised levels of CD127low/- regulatory T cells in the tumour microenvironment compared with the periphery of head and neck cancer patients [PDF]

open access: yes, 2014
Objective: Regulatory T cells (Tregs) are known to infiltrate the tumour microenvironment of many cancers, including head and neck malignancies, and are thought to contribute to the host's impaired anti-tumour immune response.

N-cadherin crosstalk with integrin weakens the molecular clutch in response to surface viscosity

open access: yesNature Communications
Mesenchymal stem cells (MSCs) interact with their surroundings via integrins, which link to the actin cytoskeleton and translate physical cues into biochemical signals through mechanotransduction.

Structural basis of human 20S proteasome biogenesis

open access: yesNature Communications
New proteasomes are produced to accommodate increases in cellular catabolic demand and prevent the accumulation of cytotoxic proteins. Formation of the proteasomal 20S core complex relies on the function of the five chaperones PAC1-4 and POMP.
