Single cell mutational analysis of PIK3CA in circulating tumor cells and metastases in breast cancer reveals heterogeneity, discordance, and mutation persistence in cultured disseminated tumor cells from bone marrow

open access: yesBMC Cancer, 2014
BackgroundTherapeutic decisions in cancer are generally guided by molecular biomarkers or, for some newer therapeutics, primary tumor genotype. However, because biomarkers or genotypes may change as new metastases emerge, circulating tumor cells (CTCs ...

Wnt Inhibition Sensitizes PD-L1 Blockade Therapy by Overcoming Bone Marrow-Derived Myofibroblasts-Mediated Immune Resistance in Tumors

open access: yesFrontiers in Immunology, 2021
Cancer-associated fibroblasts (CAFs) has been recognized as one cause of tumor resistance to immune checkpoint blockade therapy, but the underlying mechanisms still remain elusive.

Effect of IL-10-producing B cells in peripheral blood and tumor tissue on gastric cancer

open access: yesCell Communication and Signaling, 2023
Background Interleukin (IL)-10-producing B (B10) cells are generated in response to signals from the tumor microenvironment and promote tumor growth by interacting with B10 cells.

Schwann cells promote the migration and invasion of colorectal cancer cells via the activated NF-κB/IL-8 axis in the tumor microenvironment

open access: yesFrontiers in Oncology, 2022
BackgroundEvidence has shown neurons and glial cells were closely related to tumor progression. As the predominant glial cells in the external innervated nerves of the gastrointestinal, the role of Schwann cells (SCs) in colorectal cancer (CRC) has not ...

Macrophage induces anti-cancer drug resistance in canine mammary gland tumor spheroid

open access: yesScientific Reports, 2023
Tumor-associated macrophages (TAMs) play an important role in the tumor microenvironment by producing cytokines and growth factors. Furthermore, TAMs play multifunctional roles in tumor progression, immune regulation, metastasis, angiogenesis, and ...

Human macrophage-engineered vesicles for utilization in ovarian cancer treatment

open access: yesFrontiers in Oncology, 2023
BackgroundOvarian cancer is a deadly female malignancy with a high rate of recurrent and chemotherapy-resistant disease. Tumor-associated macrophages (TAMs) are a significant component of the tumor microenvironment and include high levels of M2-protumor ...

Effect of Podophyllin on Tumor Cells in Tissue Culture.

open access: yesExperimental Biology and Medicine, 1947
Conclusions1. Podophyllin exerts a selective damaging effect on mouse tumor cells in tissue culture over the concentration range 0.08-20.0 mg/1. 2. This damaging effect is more easilv reversible in normal than in tumor cells. 3. Podophyllotoxin is not as effective as podophyllin in causing selective tumor damage. 4.

Versican modulates tumor-associated macrophage properties to stimulate mesothelioma growth

open access: yesOncoImmunology, 2019
Versican promotes experimental tumor growth through cell- and non cell-autonomous mechanisms. Its role in mesothelioma progression has not been investigated so far.

Selective advantage of trisomic human cells cultured in non-standard conditions

open access: yesScientific Reports, 2016
An abnormal chromosome number, a condition known as aneuploidy, is a ubiquitous feature of cancer cells. A number of studies have shown that aneuploidy impairs cellular fitness.
