Escape from immunotherapy: possible mechanisms that influence tumor regression/progression [PDF]

open access: yes, 2004
Tumor escape is one major obstacle that has to be addressed prior to designing and delivering successful immunotherapy. There is compelling evidence to support the notion that immunogenic tumors, in murine models and cancer patients, can be rejected by ...

Digitonin‐Loaded Nanoscale Metal–Organic Framework for Mitochondria‐Targeted Radiotherapy‐Radiodynamic Therapy and Disulfidptosis

open access: yesAdvanced Materials, EarlyView.
A mitochondria‐targeted cationic nanoscale metal organic framework shows strong radiotherapy‐radiodynamic therapy effects and selectively releases digitonin in acidic tumor microenvironments to induce disulfidptosis of cancer cells and downregulate immune checkpoints in cancer and T cells, thereby eliciting strong antitumor immunity to effectively ...

The nitric oxide response in plant-associated endosymbiotic bacteria [PDF]

open access: yes, 2011
Nitric oxide (NO) is a gaseous signalling molecule which becomes very toxic due to its ability to react with multiple cellular targets in biological systems. Bacterial cells protect against NO through the expression of enzymes that detoxify this molecule

Advancements in Understanding the Physicochemical Properties of Reticular Materials: An In Situ and Operando Spectroscopic Perspective

open access: yesAdvanced Materials, EarlyView.
This review explores how in situ and operando spectroscopic techniques reveal the real‐time behavior of reticular materials, including MOFs and COFs. These methods track material formation and functionalization, structural changes, defect formation, dynamic responses to external triggers, and catalytic processes.

Single Amino Acid Substitution in Homogentisate Dioxygenase Affects Melanin Production in Bacillus thuringiensis

open access: yesFrontiers in Microbiology, 2018
Bacillus thuringiensis formulation losing its activity under field conditions due to UV radiation and photoprotection of B. thuringiensis based on melanin has attracted the attention of researchers for many years.

Copper and Iron‐Based Metal‐Organic Frameworks for Synergistic Cancer Phototherapies: Recent Advances, Challenges, and Future Prospects

open access: yesAdvanced Therapeutics, EarlyView.
The graphical abstract illustrates the combined effect of PTT and PDT using metal‐organic frameworks (MOFs) in a cancer treatment model. Tumor‐bearing mice are irradiated with different laser lights, which activate the MOF nanoparticles within cancer cells. The MOFs produce reactive oxygen species through PDT, while PTT elevates the temperature to kill

Identification of Metabolic Intermediates in Microbial Degradation of Chrysene by Armillaria sp. F022

open access: yesIndonesian Journal of Biotechnology, 2010
To degrade chrysene, a polycyclic aromatic hydrocarbon (PAH), Armillaria sp. F022, a fungus collected from a soil, was used. Maximal degradation (77%) was obtained when Armillaria sp.

The promoter from SlREO, a highly-expressed, root-specific Solanum lycopersicum gene, directs expression to cortex of mature roots [PDF]

open access: yes, 2008
Root-specific promoters are valuable tools for targeting transgene expression, but many of those already described have limitations to their general applicability.

Enhancing the Effectiveness of Chemotherapy in Osteosarcoma by Targeting Tumour‐Associated Macrophages (TAMs) through STING Activation

open access: yesAdvanced Therapeutics, EarlyView.
Osteosarcoma isa highly aggressive bone cancer with an immunosuppressive tumor microenvironment that limits immunotherapy. This study explores STING pathway activation to reprogram tumor‐associated macrophages into a tumoricidal M1‐like phenotype and enhance doxorubicin efficacy. Results show that doxorubicin alone failed to activate the STING pathway,

Characterization and evaluation of catechol oxygenases by twelve bacteria, isolated from oil contaminated soils in Malaysia [PDF]

open access: yesBiological Journal of Microorganism, 2017
Introduction: Catechol is a common intermediate compound in aromatic degradation process. Some microorganisms have this potentiality to degrade aromatic hydrocarbons by catechol dioxygenases to less toxic compounds with ability of entering the ...
