TNFAIP2 confers cisplatin resistance in head and neck squamous cell carcinoma via KEAP1/NRF2 signaling
CONCLUSIONS: Our results reveal the antioxidant and cisplatin resistance-regulating roles of the TNFAIP2/KEAP1/NRF2/JNK axis in HNSCC, suggesting that TNFAIP2 might be a potential target in improving the cisplatin treatment effect, particularly for patients with cisplatin resistance.PMID:37525222 | PMC:PMC10391982 | DOI:10.1186/s13046-023-02775-1

Non-targeting siRNA-mediated responses are associated with apoptosis in chemotherapy-induced senescent skin cancer cells
Chem Biol Interact. 2022 Nov 4:110254. doi: 10.1016/j.cbi.2022.110254. Online ahead of print.ABSTRACTIt is widely accepted that siRNA transfection can promote some off-target effects in the genome; however, little is known about how the cells can respond to the presence of non-viral dsRNA. In the present study, non-targeting control siRNA (NTC-siRNA) was used to evaluate its effects on the activity of pathogen and host-derived nucleic acid-associated signaling pathways such as cGAS-STING, RIG-I, MDA5 and NF-κB in A431 skin cancer cells and BJ fibroblasts. NTC-siRNA treatment promoted cytotoxicity in cancer cells. Furtherm...

Cancers, Vol. 14, Pages 5363: Electroporation in Head-and-Neck Cancer: An Innovative Approach with Immunotherapy and Nanotechnology Combination
i Marco Benazzo Squamous cell carcinoma is the most common malignancy that arises in the head-and-neck district. Traditional treatment could be insufficient in case of recurrent and/or metastatic cancers; for this reason, more selective and enhanced treatments are in evaluation in preclinical and clinical trials to increase in situ concentration of chemotherapy drugs promoting a selectively antineoplastic activity. Among all cancer treatment types (i.e., surgery, chemotherapy, radiotherapy), electroporation (EP) has emerged as a safe, less invasive, and effective approach for cancer treatment. Reversible EP, using an...

Dual inhibition of autophagy and PI3K/mTOR pathway as a potential therapeutic strategy against laryngeal squamous cell carcinoma
CONCLUSIONS: NVP-BEZ235 exerted potent antitumor effects on LSCC, especially when combined with the autophagy inhibitor both in vitro and vivo, providing convincing experimental data for new molecular targeted therapy for LSCC.PMID:35706786 | PMC:PMC9189222 | DOI:10.21037/tcr-21-2325

Cancers, Vol. 14, Pages 2151: Role of Amino Acid Transporter SNAT1/SLC38A1 in Human Melanoma
In this study, we revealed a significant upregulation of SNAT1 expression in human melanoma tissue in comparison to healthy epidermis and an increased SNAT1 expression level in human melanoma cell lines when compared to normal human melanocytes (NHEMs). We demonstrated that functional inhibition of SNAT1 with α-(methylamino) isobutyric acid (MeAIB), as well as siRNA-mediated downregulation reduces cancer cell growth, cellular migration, invasion, and leads to induction of senescence in melanoma cells. Consequently, these results demonstrate that the amino acid transporter SNAT1 is essential for cancer growth,...

Upregulation of OATP1A2 in human oesophageal squamous cell carcinoma cells via the HDAC6-GCN5/PCAF-H3K9Ac axis
In conclusion, this study indicated that suppression of OATP1A2 would inhibit the progression and prognosis in ESCC.PMID:34823432 | DOI:10.1080/00498254.2021.2001076

ACSS2/AMPK/PCNA pathway ‑driven proliferation and chemoresistance of esophageal squamous carcinoma cells under nutrient stress.
This study investigated the functions of nutrient stress (NS)‑mediated acetyl‑CoA synthetase short‑chain family member 2 (ACSS2) in cell proliferation and cisplatin‑resistance and examined its combined effects with proliferating cell nuclear antigen (PCNA), a key regulator of DNA replication and repair. Here, it was demonstrated that under NS, when the AMP‑activated protein kinase (AMPK) pathway was activated, ESCC cells maintained proliferation and chemoresistance was distinctly upregulated as determined by CCK‑8 assay. As determined using immunoblotting and RT‑qPCR, compared with normal esophageal epithelia...

TNF ‑α‑mediated upregulation of SOD‑2 contributes to cell proliferation and cisplatin resistance in esophageal squamous cell carcinoma.
TNF‑α‑mediated upregulation of SOD‑2 contributes to cell proliferation and cisplatin resistance in esophageal squamous cell carcinoma. Oncol Rep. 2019 Jul 26;: Authors: Zuo J, Zhao M, Liu B, Han X, Li Y, Wang W, Zhang Q, Lv P, Xing L, Shen H, Zhang X Abstract Intrinsic and acquired resistance of cancer to radio‑and chemotherapy is one of the major challenges in the treatment of esophageal squamous cell carcinoma (ESCC). Elevated reactive oxygen species (ROS) play an important role in the resistance to cisplatin in ESCCs. Super dismutase [Mn], mitochondrial (SOD‑2), an important primary antio...

Overexpression of CASC11 in ovarian squamous cell carcinoma mediates the development of cancer cell resistance to chemotherapy.
Abstract LncRNA CASC11 promotes gastric cancer and colon cancer. Our study analyzed the role of CASC11 in ovarian squamous cell carcinoma (OSCC). In the present study we showed that plasma CASC11 was upregulated in OSCC, and the upregulation of CASC11 distinguished OSCC patients from control group. Plasma levels of CASC11 were further increased after chemotherapy. Treatment with oxaliplatin, tetraplatin, cisplatin, and carboplatin mediated the upregulation of CASC11 in cells of OSCC cell line. In addition, overexpression of CASC11 led to increased cancer cell viability under oxaliplatin, tetraplatin, cisplatin, an...

Human CAR NK Cells: A New Non-viral Method Allowing High Efficient Transfection and Strong Tumor Cell Killing
In conclusion, the method of NK cell transfection described in our present study is highly efficient, does not require expensive dedicated structures necessary for viral transduction and avoids possible risks associated with the use of viral vectors. Importantly, it may be applied to NK cells or NK-92 cell line, greatly improving their anti-tumor activity and providing a new NK cell-based platform for new protocols of adoptive immuno-therapy of cancer. Ethics Statement The Ethical Committee of IRCCS Bambino Gesù Pediatric Hospital approved the study (825/2014). Author Contributions TI designed and performed res...

Myeloid Derived Suppressor Cells Interactions With Natural Killer Cells and Pro-angiogenic Activities: Roles in Tumor Progression
Conclusions MDSC are major players in the immunosuppressive scenario in cancer, thanks to their phenotype heterogeneity and critical interaction with several innate immune cells, thus representing a crucial target in oncology. Here we reviewed the interactions of MDSCs with NK cells. The contribution of key cytokines, chemokines and mediators active in this process have been discussed. We also described the contribution of MDSC on angiogenesis directly or indirectly through interactions with NK and immunosuppressive activities. A parallel of the cancer associated to the decidual counterpart of these cells is discussed, a...
