Research Progress of Metformin in the Treatment of Oral Squamous Cell Carcinoma
Endocrinology. 2023 Sep 20:bqad139. doi: 10.1210/endocr/bqad139. Online ahead of print.ABSTRACTOral squamous cell carcinoma (OSCC) is one of the most common malignancies with high mortality, posing a great threat to both human physical and mental health. With the advancement of scientific research, a variety of cancer therapies have been used for OSCC treatment. However, the prognosis of OSCC shows no significant improvement. Metformin has been recognized as the first-line drug for the treatment of diabetes, and recent studies have shown that metformin has a remarkable suppressive effect on tumor progression. Metformin can...

STAT3-EphA7 axis contributes to the progression of esophageal squamous cell carcinoma
CONCLUSION: Our results showed that the transcriptional expression of EphA7 was increased by activated STAT3, and the STAT3 signaling may act through EphA7 to promote the development of ESCC.PMID:37738252 | DOI:10.1080/0284186X.2023.2259601

Extended duration of treatment using reduced-frequency dosing of anti-PD-1 therapy in patients with advanced melanoma and Merkel cell carcinoma
CONCLUSIONS: ICI administration at RFD can allow extension of treatment duration, while preserving efficacy and reducing logistical and financial burden. RFD approach deserves further exploration in prospective clinical trials.PMID:37733060 | DOI:10.1007/s00262-023-03539-8

Boiling histotripsy induces dendritic cell activation and acquisition of antigen in tumor draining lymph nodes
bioRxiv. 2023 Sep 6:2023.09.02.552844. doi: 10.1101/2023.09.02.552844. Preprint.ABSTRACTBoiling histotripsy (BH), a mechanical focused ultrasound ablation strategy, can elicit intriguing signatures of anti-tumor immunity. However, the influence of BH on dendritic cell function is unknown, compromising our ability to optimally combine BH with immunotherapies to control metastatic disease. Here, by applying BH to B16F10 melanoma expressing a ZsGreen antigen in a monotherapy protocol that elicits abscopal tumor control, we observed a marked increase in antigen acquisition by multiple phagocytic immune cells, including convent...

Indoloquinazoline alkaloids suppress angiogenesis and inhibit metastasis of melanoma cells
Bioorg Chem. 2023 Sep 18;141:106873. doi: 10.1016/j.bioorg.2023.106873. Online ahead of print.ABSTRACTMetastasis is the leading cause of cancer-related mortality, targeting angiogenesis emerges as a therapeutic strategy for the treatment of melanoma metastasis. Discovery of new antiangiogenic compounds with specific mechanism of action is still desired. In present study, a bioassay-guidance uncovers the EtOAc extract of a marine-derived fungus Aspergillus clavutus LZD32-24 with significant inhibitory activity against the angiogenesis in Tg (fli1a: EGFP) zebrafish model. Extensive chromatographic fractionation led to the is...

Topical Calcipotriol Plus Imiquimod Immunotherapy for Nonkeratinocyte Skin Cancers
In this study, we demonstrate that topical TSLP cytokine inducers-calcipotriol and retinoic acid-synergize with IMQ to activate CD4+ T-cell immunity against nonkeratinocyte cutaneous malignancies. Topical calcipotriol plus IMQ treatment reduced breast tumor growth compared with calcipotriol or IMQ alone (P < 0.0001). Calcipotriol plus IMQ-mediated tumor suppression was associated with significant infiltration of CD4+ effector T cells in the tumor microenvironment. Notably, topical calcipotriol plus IMQ immunotherapy enabled immune checkpoint blockade therapy to effectively control immunologically cold breast tumors, whi...

Role of tissue markers associated with tumor microenvironment in the progression and immune suppression of oral squamous cell carcinoma
Med Oncol. 2023 Sep 20;40(10):303. doi: 10.1007/s12032-023-02169-5.ABSTRACTHead and neck cancers (HNC) continues to dominate major cancers contributing to mortality worldwide. Squamous cell carcinoma is the major type of HNC. Oral Squamous Cell Carcinoma grouped under HNC is a malignant tumor occurring in the oral cavity. The primary risk factors of OSCC are tobacco, alcohol consumption, etc. This review focuses on modulations, mechanisms, growth and differentiation of oral squamous cell carcinoma. Cancer cell surrounds itself with a group of elements forming a favorable environment known as tumor microenvironment (TME). I...

Durable complete response to early immunotherapy discontinuation in a kidney transplant recipient with advanced cutaneous squamous cell carcinoma: A case report and review of literature
CONCLUSION: Organ transplant recipients with complete response to immunotherapy for cutaneous squamous cell carcinoma may continue to respond despite early treatment cessation. This may reduce the risks of late immune-related adverse events and acute graft rejection.PMID:37734447 | DOI:10.1016/j.trim.2023.101932

Different mechanisms of CD200-CD200R induce diverse outcomes in cancer treatment
Math Biosci. 2023 Sep 19:109072. doi: 10.1016/j.mbs.2023.109072. Online ahead of print.ABSTRACTThe CD200 is a cell membrane protein expressed by tumor cells, and its receptor CD200 receptor (CD200R) is expressed by immune cells including macrophages and dendritic cells. The formation of CD200-CD200R inhibits the cellular functions of the targeted immune cells, so CD200 is one type of the immune checkpoint and blockade CD200-CD200R formation is a potential cancer treatment. However, the CD200 blockade has opposite treatment outcomes in different types of cancers. For instance, the CD200R deficient mice have a higher tumor l...
