The IL-8/NF-κB feedback loop confers a paclitaxel-sensitive/doxorubicin-resistant phenotype in triple-negative breast cancer.

Triple-negative breast cancer (TNBC) is a subtype of breast cancer that is highly metastatic compared with other BC subtypes. Taxane- and anthracycline-based therapies remain the main clinical TNBC regimens. However, TNBC patients usually suffer through chemotherapy owing to the lack of valid biomarkers to predict therapeutic effectiveness.

Mastectomy Alone or with Immediate Breast Reconstruction: Trend, Precipitating Factors, Patients Reported Outcome, and Oncologic Safety Analysis with and without Propensity Score Matching from 3759 Mastectomy Patients.

Background: In the current study, we surveyed the trend of breast cancer operations in the past two decades and compared mastectomy alone or with immediate breast reconstruction (IBR) with the measurement of the outcome reported by patients and oncologic safety evaluation.

Methods: A retrospective study surveyed the trends in breast cancer surgery methods at a single institution between January 2000 and December 2021. Clinical manifestations, outcomes, patient-reported outcome measures, and oncologic safety evaluations between mastectomy alone or with IBR were analyzed, with and without propensity score matching (PSM).

Material surface conjugated with fibroblast growth factor-2 for pluripotent stem cell culture and differentiation.

Fibroblast growth factor-2 (FGF-2) is a critical molecule for sustaining the pluripotency of human pluripotent stem (PS) cells. However, FGF-2 is extremely unstable and cannot be stored long periods at room temperature. Therefore, the following FGF-2-conjugated cell culture materials were developed to stabilize FGF-2: FGF-2-conjugated polyvinyl alcohol (PVAI-C-FGF) hydrogels and FGF-2-conjugated carboxymethyl cellulose-coated (CMC-C-FGF) dishes.

Vedolizumab serum trough concentrations with and without thiopurines in ulcerative colitis: The prospective VIEWS pharmacokinetics study.

Background: Ulcerative colitis (UC) is a chronic inflammatory condition requiring continuous treatment and monitoring. There is limited pharmacokinetic data on vedolizumab during maintenance therapy and the effect of thiopurines on vedolizumab trough concentrations is unknown.

Aim: To investigate the exposure-response relationship of vedolizumab and the impact of thiopurine withdrawal in UC patients who have achieved sustained clinical and endoscopic remission during maintenance therapy.

GRK6 palmitoylation dictates triple-negative breast cancer metastasis via recruiting the β-Arrestin 2/MAPKs/NF-κB signaling axis.

Background: Triple negative breast cancer (TNBC) belongs to the worst prognosis of breast cancer subtype probably because of distant metastasis to other organs, e.g. lungs.

Effects of ECM protein-coated surfaces on the generation of retinal pigment epithelium cells differentiated from human pluripotent stem cells.

Retinal degeneration diseases, such as age-related macular degeneration (AMD) and retinitis pigmentosa (RP), initially manifest as dysfunction or death of the retinal pigment epithelium (RPE). Subretinal transplantation of human pluripotent stem cell (hPSC)-derived RPE cells has emerged as a potential therapy for retinal degeneration. However, RPE cells differentiated from hPSCs using current protocols are xeno-containing and are rarely applied in clinical trials.

Nurses' perspectives on child-friendly care needs in emergency departments: A qualitative study.

Background: Children can become anxious when undergoing emergency medical treatment. Therefore, emergency departments should be child friendly. This study explored emergency nurses' perspectives on children's needs during emergency care.

Next-generation materials for RNA-lipid nanoparticles: lyophilization and targeted transfection.

RNA, including mRNA, siRNA and miRNA, is part of a new class of patient treatments that prevent and treat several diseases. As an alternative to DNA therapy using plasmid DNA, RNA functions in the cellular cytosol, avoiding the potential risks of insertion into patient genomes. RNA drugs, including mRNA vaccines, need carrier materials for delivery into the patient's body.

NEDD8 promotes radioresistance via triggering autophagy formation and serves as a novel prognostic marker in oral squamous cell carcinoma.

Background: Radiotherapy is the first-line regimen for treating oral squamous cell carcinoma (OSCC) in current clinics. However, the development of therapeutic resistance impacts the anticancer efficacy of irradiation in a subpopulation of OSCC patients. As a result, discovering a valuable biomarker to predict radiotherapeutic effectiveness and uncovering the molecular mechanism for radioresistance are clinical issues in OSCC.

Multifactorial Analysis of Clinical Prognosis of Liver Metastasis and Vascular Intervention Combined with Ablation in Colorectal Cancer.

Colorectal cancer is one of the leading causes of deaths in China. The initial stages of colorectal cancer can be treated by surgery, radiation, and chemotherapy. However, in the advanced stages, it warrants an application of multimodality treatment.

Purification of Colon Carcinoma Cells from Primary Colon Tumor Using a Filtration Method via Porous Polymeric Filters.

Cancer stem cells (CSCs) or cancer-initiating cells (CICs) are key factors for tumor generation and metastasis. We investigated a filtration method to enhance CSCs (CICs) from colon carcinoma HT-29 cells and primary colon carcinoma cells derived from patient colon tumors using poly(lactide--glycolic acid)/silk screen (PLGA/SK) filters. The colon carcinoma cell solutions were permeated via porous filters to obtain a permeation solution.

RGL2 Drives the Metastatic Progression of Colorectal Cancer via Preventing the Protein Degradation of β-Catenin and KRAS.

Colorectal cancer (CRC) is one of the most common cancers and results in high mortality worldwide, owing to cancer progression, i.e., metastasis.

Cervical Tuberculosis Combined With Papillary Thyroid Carcinoma With Lateral Neck Metastasis.

Extrapulmonary tuberculosis in the head and neck region accounts for 10% of all tuberculosis cases. Cervical lymph nodes are the most common sites of head and neck tuberculosis and often mimics neck metastasis leading to overstaging and overtreatment. Fine needle aspiration has proven effective in diagnosing cervical tuberculosis.

DNA polymerase theta repression enhances the docetaxel responsiveness in metastatic castration-resistant prostate cancer.

Objective: Docetaxel remains a main treatment for metastatic castration-resistant prostate cancer (mCRPC); however, the development of docetaxel resistance has been found in some mCRPC patients. The aim of this work is to identify an effective biomarker for predicting therapeutic effectiveness of docetaxel in mCRPC patients.

Methods: We examined DNA polymerase theta (POLQ) expression in The Cancer Genome Atlas (TCGA) database and Tissue microarray.

TNFSF13 upregulation confers chemotherapeutic resistance via triggering autophagy initiation in triple-negative breast cancer.

Since chemotherapy is a main strategy to treat triple-negative breast cancer (TNBC) patients currently, identifying a biomarker to predict chemotherapeutic responses is urgently needed for patients to avoid suffering through unnecessary chemotherapeutic treatments. Here, we found that the endogenous expression of TNFSF13 in a panel of TNBC cell lines highly correlates with paclitaxel (PTX) and doxorubicin IC concentrations. Whereas knocking down TNFSF13 enhances PTX effectiveness in PTX-insensitive MDA-MB231 cells, recombinant TNFSF13 (recTNFSF13) desensitizes PTX-sensitive HCC1806 cells to PTX treatment.

The Gαh/phospholipase C-δ1 interaction promotes autophagosome degradation by activating the Akt/mTORC1 pathway in metastatic triple-negative breast cancer.

Lung metastasis (LM) is commonly found in triple-negative breast cancer (TNBC); however, the molecular mechanism underlying TNBC metastasis to lungs remains largely unknown. We thus aimed to uncover a possible mechanism for the LM of TNBC. Here we show that the phosphorylation of Akt and mTORC1 was positively but the autophagy activity was negatively correlated with endogenous Gαh levels and cell invasion ability in TNBC cell lines.

IMPA2 Downregulation Enhances mTORC1 Activity and Restrains Autophagy Initiation in Metastatic Clear Cell Renal Cell Carcinoma.

Although mTOR inhibitors have been approved as first-line therapy for treating metastatic clear cell renal cell carcinoma (ccRCC), the lack of useful markers reduces their therapeutic effectiveness. The objective of this study was to estimate if inositol monophosphatase 2 (IMPA2) downregulation refers to a favorable outcome in metastatic ccRCC receiving mTOR inhibitor treatment. Gene set enrichment analysis predicted a significant activation of mTORC1 in the metastatic ccRCC with IMPA2 downregulation.

Histone 2A Family Member J Drives Mesenchymal Transition and Temozolomide Resistance in Glioblastoma Multiforme.

Glioblastoma multiforme (GBM) is the most aggressive brain tumor and has a poor prognosis and is poorly sensitive to radiotherapy or temozolomide (TMZ) chemotherapy. Therefore, identifying new biomarkers to predict therapeutic responses of GBM is urgently needed. By using The Cancer Genome Atlas (TCGA) database, we found that the upregulation of histone 2A family member J (H2AFJ), but not other H2AFs, is extensively detected in the therapeutic-insensitive mesenchymal, IDH wildtype, MGMT unmethylated, or non-G-CIMP GBM and is associated with poor TMZ responsiveness independent of radiation.

Nicotinic Acetylcholine Receptor Subunit Alpha-5 Promotes Radioresistance via Recruiting E2F Activity in Oral Squamous Cell Carcinoma.

Radiotherapy is commonly used to treat patients with oral squamous cell carcinoma (OSCC), but a subpopulation of OSCC patients shows a poor response to irradiation treatment. Therefore, identifying a biomarker to predict the effectiveness of radiotherapy in OSCC patients is urgently needed. In silico analysis of public databases revealed that upregulation of , the gene encoding nicotinic acetylcholine receptor subunit alpha-5, is extensively detected in primary tumors compared to normal tissues and predicts poor prognosis in OSCC patients.

Upregulation Predicts a Poor Prognosis and Associates with a Possible Mechanism for Paclitaxel Resistance in Ovarian Cancer.

Paclitaxel (PTX) is a common regimen used to treat patients with ovarian cancer. Although approximately 60% of ovarian cancer patients exhibit a pathologic complete response (pCR), approximately 40% of patients appear to be insensitive to PTX adjuvant therapy. Thus, identifying a useful biomarker to predict pCR would be of great help to ovarian cancer patients who decide to receive PTX treatment.

Clinicopathologic factors related to surgical margin involvement, reoperation, and residual cancer in primary operable breast cancer - An analysis of 2050 patients.

Background: To evaluate whether clinicopathologic factors are related to surgical margin involvement, reoperation, and residual cancer in primary operable breast cancer.

Methods: Identification of patients at increased risk for positive surgical margins may enhance clinical preoperative decision-making and lower the reoperation rate. In this retrospective study, we analyzed the factors associated with positive surgical margins, the need for re-excision, and residual cancer detection in re-excised specimens in a cohort of 2050 women who underwent either breast-conserving surgery (BCS) or mastectomy for primary operable breast cancer.

upregulation predicts a poor response to paclitaxel in patients with triple-negative breast cancer.

Paclitaxel is a first-line chemotherapeutic for patients with breast cancer, particularly triple-negative breast cancer (TNBC). Molecular markers for predicting pathologic responses to paclitaxel treatment is thus urgently needed since paclitaxel resistance is still a clinical issue in treating TNBCs. We investigated the transcriptional profiling of consensus genes in HCC38 (paclitaxel-sensitive) and MDA-MB436 (paclitaxel-resistant) TNBC cells post-treatment with paclitaxel.

High-level expression of ARID1A predicts a favourable outcome in triple-negative breast cancer patients receiving paclitaxel-based chemotherapy.

Paclitaxel-based chemotherapy is a common strategy to treat patients with triple-negative breast cancer (TNBC). As paclitaxel resistance is still a clinical issue in treating TNBCs, identifying molecular markers for predicting pathologic responses to paclitaxel treatment is thus urgently needed. Here, we report that an AT-rich interaction domain 1A (ARID1A) transcript is up-regulated in paclitaxel-sensitive TNBC cells but down-regulated in paclitaxel-resistant cells upon paclitaxel treatment.
