Efficacy and safety of a "sandwich therapy" based on staged stereotactic radiosurgery and bevacizumab for large brainstem metastases.

Objective: Gamma Knife stereotactic radiosurgery (SRS) is an effective therapeutic option for unresectable brainstem metastases. Currently, staged stereotactic radiosurgery (SSRS) has become available for large brainstem metastases（≥ 1 cm） despite the limitation of peritumoral edema. The authors developed the so-called "sandwich therapy" which integrated 2-stage stereotactic radiosurgery (2-SSRS) with bevacizumab for peritumoral edema reduction and local control of large brainstem metastases.

N7-methylguanosine modification: from regulatory roles to therapeutic implications in cancer.

N7-methylguanosine (m7G) is one of the most common post-transcriptional epigenetic modifications. Different m7G methyltransferases (writers) load the m7G-cap at the 5'-terminal or inside the RNAs. For example, writers such as methyltransferase-like 1 (METTL1)/WD repeat domain 4 (WDR4) and Williams-Beuren syndrome chromosome region 22 (WBSCR22) have been reported in mammals to promote cell proliferation, EMT, and chemoresistance in massive quantities of cancers.

An immunogenic cell death-related classification predicts response to immunotherapy and prognosis in triple-negative breast cancer.

Objective: Immunogenic cell death (ICD) of tumor cells is characterized by the induction of adaptive and innate immune responses, which in turn activates the immune surveillance and improves the efficacy of immunotherapy. In this study, we aimed to investigate the effect of ICD on the prognosis and the efficacy of immunotherapy in patients with triple-negative breast cancer (TNBC).

Methods: TNBC samples from The Cancer Genome Atlas-Breast Cancer (TCGA-BRCA) dataset were divided into two subtypes (ICD-high and ICD-low) based on the ICD status by using the consensus clustering method, and their genomic landscape and immune landscape were delineated.

BRAF mutation promoted the growth and chemoresistance of colorectal cancer.

BRAF mutation occurs frequently in colorectal cancer (CRC), which is associated with poor prognosis. Numerous clinical studies have indicated the undesirable effect of BRAF mutation in CRC patients; however, in vitro studies on the role and functional mechanism of BRAF mutation in CRC are limited. Here, we analyzed the association between BRAF mutation and the clinical features of CRC by using data deposited in the TCGA database.

Hepcidin as a prognostic biomarker in clear cell renal cell carcinoma.

Clear cell renal cell carcinoma (ccRCC) is a common malignancy of urologic neoplasms. Hepcidin is a pivotal modulator of iron metabolism involved in human cancers; however, the biological significance of hepcidin in ccRCC remains to be fully understood. Therefore, in this study, we evaluated the expression profiles of hepcidin in ccRCC from several public databases and found that hepcidin expression was upregulated in ccRCC, which was further validated in ccRCC cell lines, clinical samples, and tissue microarray (TMA) quantitative real-time PCR and immunohistochemistry.

PYCR1 regulates glutamine metabolism to construct an immunosuppressive microenvironment for the progression of clear cell renal cell carcinoma.

Metabolic reprogramming is critical for the setup of the tumor microenvironment (TME). Glutamine has slipped into the focus of research of cancer metabolism, but its role in clear cell renal cell carcinoma (ccRCC) remains vague. Our study aimed to investigate the regulatory mechanism of glutamine in ccRCC and its prognostic value.

Immunotherapy and immunobiomarker in breast cancer: current practice and future perspectives.

Among the new cancer cases and resulting deaths among women worldwide, breast cancer is the most significant threat to women's health. In recent years, immunotherapy was initially used to treat patients with metastatic breast cancer, where it demonstrated its unique value by providing a novel way to improve therapeutic effects and prolong survival time. With the development of clinical trials related to immunotherapy for breast cancer, tumour vaccines, such as DNA vaccines, have been observed to improve the disease-free survival (DFS) and overall survival (OS) of patients.

Impact of exogenous metal ions on peri-implant bone metabolism: a review.

The development of effective methods to promote the osseointegration of dental implants by surface modification is an area of intense research in dental materials science. Exogenous metal ions present in the implant and surface modifications are closely related to the bone metabolism around the implant. In the complex oral microenvironment, the release of metal ions caused by continuous corrosion of dental implants has an unfavorable impact on the surrounding tissue, and then affects osseointegration, leading to bad results such as loosening and falling off in the late stage of the implant.

Methods: The clinicopathological data of 54 patients with CD hospitalized in the First Affiliated Hospital of Nanjing Medical University were retrospectively analyzed.

Pyrroloquinoline quinone inhibits ligature-induced alveolar bone loss through regulation of redox balance and cell senescence.

It has been demonstrated that oxidative stress is related to periodontitis, and that pyrroloquinoline quinine (PQQ) acts as a powerful antioxidant. This study aimed to explore the effect of PQQ on ligature-induced alveolar bone loss in experimental periodontitis (EP) mice with/without PQQ in the diet. EP mice received a diet supplemented with PQQ for 2 weeks and were compared with sham (control) mice as well as untreated EP mice.

Exosomal circRNAs: a new communication method in cancer.

Exosomes are extracellular vesicles with unique membrane markers and components that participate in cellular communication. The contents of exosomes, including growth factors, microRNAs, long noncoding RNAs, and circular RNAs (circRNAs), have been recognized as prognostic biomarkers and promote cancer progression through cancer cell growth, metastasis, angiogenesis, and cancer development. One of the components of exosomes, circRNAs, are covalently closed and prevented from degrading, which results in their continually accumulating in exosomes.

The roles of AMPK-mediated autophagy and mitochondrial autophagy in a mouse model of imiquimod-induced psoriasis.

Background: Psoriasis is a systemic inflammatory disease characterized by epidermal hyperplasia and skin inflammatory infiltrates. Inactivation of AMPK has been shown to decrease autophagy, thereby inhibiting elimination of inflammatory factors and harmful substances, and aggravating psoriasis. However, the molecular mechanism through which AMPK affects psoriasis remains to be further explored.
