Cytotoxic Activity of Alpinumisoflavone from Erythrina poeppigiana (Leguminosae) Against Colon Cancer (WiDr), Cervical Cancer (Hela), and Hepatoma Cancer (HepG2) Cells

open access: yesHayati Journal of Biosciences, 2019
Cancer is the second cause of death after cardiovascular diseases in the world. Anticancer prevention used can cause undesirable things. Flavonoids are secondary metabolites derived from natural products that are useful for anticancer treatment.

Induction of IL 2 receptor expression and cytotoxicity of thymocytes by stimulation with TCF1 [PDF]

open access: yes, 1985
We investigated the role of T cell cytotoxicity inducing factor 1 (TCF1) in the induction of a cytotoxic T cell response. We found that help-deficient thymocyte cultures supplied with saturating amounts of purified IL 2 did not develop CTL in a 5-day ...

Fusion of Sendai virus with the target cell membrane is required for T cell cytotoxicity [PDF]

open access: yes, 1978
INFECTION of mice with viruses can generate cytotoxic T lymphocytes (CTL) which show restricted specificity for target cell lysis. Specific lysis requires that the virus used to prime the target cells must be of the same type as that used to sensitise ...

Cell‐cycle‐specific lesion evolution rather than inhibition of double‐strand‐break repair underpins cisplatin radiosensitization

open access: yesMolecular Oncology, EarlyView.
We analyze cisplatin–DNA adducts (CDAs) and double‐strand breaks (DSBs) in a cell‐cycle‐dependent manner. We find that CDAs form similarly across all cell cycle phases. DSBs arise only in S‐phase. CDAs might not directly impair DSB repair, but S‐phase DSB lesions evolve in the presence of CDAs and disrupt repair in G2, also causing radiosensitization ...

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer

open access: yesMolecular Oncology, EarlyView.
Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...

Antioxidant and Cytotoxic Activity of Water Ethanol Extracts from the Mycelium of Inonotus rheades (Pers.) Bondartsev & Singer [PDF]

open access: yesJournal of Stress Physiology & Biochemistry, 2016
The important problem of current research is the search for bioactive natural compounds. We have previously demonstrated high in vitro antiradical activity of water ethanol extracts (WEE) from the mycelium species of the genus Inonotus rheades.

Capacity of different cell types to stimulate cytotoxic T lymphocyte precursor cells in the presence of interleukin 2 [PDF]

open access: yes, 1984
Plastic-adherent cells enriched for dendritic cells (AC) were found to be among the most potent stimulator cells for the activation of cytotoxic T lymphocytes (CTL) in vitro in the presence of interleukin 2 (IL 2) and a constant second set of allogeneic ...

Clinical significance of plasmacytoid dendritic cells and myeloid-derived suppressor cells in melanoma [PDF]

open access: yes, 2015
Background: Immune markers in the peripheral blood of melanoma patients could provide prognostic information. However, there is currently no consensus on which circulating cell types have more clinical impact.

Cytotoxicity and antiangiogenic activity of grandisin

open access: yesJournal of Pharmacy and Pharmacology, 2009
Abstract Objectives The antitumoural properties of grandisin, a tetrahydrofuran neolignan from Piper solmsianum, were investigated by in-vitro and in-vivo assays using the Ehrlich ascites tumoural (EAT) model. Methods Viability of the

Proteasome inhibitor, ixazomib prevents topoisomerase‐I degradation and reverses irinotecan resistance in colorectal cancer

open access: yesMolecular Oncology, EarlyView.
Ixazomib inhibits proteasome‐mediated degradation of topoisomerase I induced by irinotecan, thereby restoring drug sensitivity and promoting tumor cell death in colorectal cancer. Irinotecan, a topoisomerase I (topoI) inhibitor, is widely used for colorectal cancer, but resistance remains a major clinical challenge.
