The MLL1-H3K4me3 Axis-Mediated PD-L1 Expression and Pancreatic Cancer Immune Evasion
- Chunwan Lu, A. V. Paschall, +6 authors K. Liu
- Biology, Medicine
- Journal of the National Cancer Institute
- 2017
BACKGROUND
Pancreatic cancer is one of the cancers where anti-PD-L1/PD-1 immunotherapy has been unsuccessful. What confers pancreatic cancer resistance to checkpoint immunotherapy is unknown. The aim… Expand
H3K9 Trimethylation Silences Fas Expression To Confer Colon Carcinoma Immune Escape and 5-Fluorouracil Chemoresistance
- A. V. Paschall, D. Yang, +9 authors K. Liu
- Biology, Medicine
- The Journal of Immunology
- 15 August 2015
The Fas–FasL effector mechanism plays a key role in cancer immune surveillance by host T cells, but metastatic human colon carcinoma often uses silencing Fas expression as a mechanism of immune… Expand
An osteopontin/CD44 immune checkpoint controls CD8+ T cell activation and tumor immune evasion
- John D Klement, A. V. Paschall, +7 authors K. Liu
- Biology, Medicine
- The Journal of clinical investigation
- 3 December 2018
Despite breakthroughs in immune checkpoint inhibitor (ICI) immunotherapy, not all human cancers respond to ICI immunotherapy and a large fraction of patients with the responsive types of cancers do… Expand
CD133+CD24lo defines a 5-Fluorouracil-resistant colon cancer stem cell-like phenotype
- A. V. Paschall, D. Yang, +6 authors K. Liu
- Medicine
- Oncotarget
- 21 September 2016
The chemotherapeutic agent 5-Fluorouracil (5-FU) is the most commonly used drug for patients with advanced colon cancer. However, development of resistance to 5-FU is inevitable in almost all… Expand
Ceramide targets xIAP and cIAP1 to sensitize metastatic colon and breast cancer cells to apoptosis induction to suppress tumor progression
- A. V. Paschall, M. Zimmerman, +8 authors K. Liu
- Medicine
- BMC Cancer
- 15 January 2014
BackgroundCeramide is a bioeffector that mediates various cellular processes, including apoptosis. However, the mechanism underlying ceramide function in apoptosis is apparently cell type-dependent… Expand
An Orthotopic Mouse Model of Spontaneous Breast Cancer Metastasis.
- A. V. Paschall, K. Liu
- Medicine
- Journal of visualized experiments : JoVE
- 14 August 2016
Metastasis is the primary cause of mortality of breast cancer patients. The mechanism underlying cancer cell metastasis, including breast cancer metastasis, is largely unknown and is a focus in… Expand
T Cell–Mediated Humoral Immune Responses to Type 3 Capsular Polysaccharide of Streptococcus pneumoniae
- Dustin R Middleton, L. Sun, A. V. Paschall, Fikri Y. Avci
- Biology, Medicine
- The Journal of Immunology
- 15 July 2017
Most pathogenic bacteria express surface carbohydrates called capsular polysaccharides (CPSs). CPSs are important vaccine targets because they are easily accessible and recognizable by the immune… Expand
An essential role of Ffar2 (Gpr43) in dietary fibre-mediated promotion of healthy composition of gut microbiota and suppression of intestinal carcinogenesis
- S. Sivaprakasam, A. Gurav, +20 authors N. Singh
- Biology, Medicine
- Oncogenesis
- 1 June 2016
Composition of the gut microbiota has profound effects on intestinal carcinogenesis. Diet and host genetics play critical roles in shaping the composition of gut microbiota. Whether diet and host… Expand
The NF-κB p65 and p50 homodimer cooperate with IRF8 to activate iNOS transcription
- Priscilla S. Simon, Sarah K. Sharman, +4 authors K. Liu
- Biology, Medicine
- BMC Cancer
- 23 October 2015
BackgroundInducible nitric oxide synthase (iNOS) metabolizes L-arginine to produce nitric oxide (NO) which was originally identified in myeloid cells as a host defense mechanism against pathogens.… Expand
IFNγ Induces DNA Methylation–Silenced GPR109A Expression via pSTAT1/p300 and H3K18 Acetylation in Colon Cancer
- Kankana Bardhan, A. V. Paschall, +11 authors K. Liu
- Biology, Medicine
- Cancer Immunology Research
- 3 March 2015
Bardhan and colleagues show that short-chain fatty acid receptor GPR109A functions as a tumor suppressor that is silenced by DNA methylation in colon cancer, while host immune cytokine IFNγ… Expand
