Mitophagy: insights into its signaling molecules, biological functions, and therapeutic potential in breast cancer.

Mitophagy, a form of selective autophagy that removes damaged or dysfunctional mitochondria, plays a crucial role in maintaining mitochondrial and cellular homeostasis. Recent findings suggest that defective mitophagy is closely associated with various diseases, including breast cancer. Moreover, a better understanding of the multifaceted roles of mitophagy in breast cancer progression is crucial for the treatment of this disease.

Patient-Reported Outcomes and Complication Profiles of Implant-Based Breast Reconstruction in Patients With Postmastectomy Radiation Therapy.

Objective: This study aims to investigate the patient-reported outcomes (PROs) and complications of distinct implant-based breast reconstruction modality for patients with postmastectomy radiation therapy (PMRT).

Methods: A retrospective review was conducted on breast cancer patients with stage II-III disease who performed implant-based breast reconstruction following with PMRT between September 2016 and April 2022. The patients were categorized into two matched groups: (1) patients receiving prepectoral breast reconstruction (PBR) or (2) subpectoral breast reconstruction (SBR) followed by PMRT.

Crosstalk between cancer-associated fibroblasts and regulated cell death in tumors: insights into apoptosis, autophagy, ferroptosis, and pyroptosis.

Cancer-associated fibroblasts (CAFs), the main stromal component of the tumor microenvironment (TME), play multifaceted roles in cancer progression through paracrine signaling, exosome transfer, and cell interactions. Attractively, recent evidence indicates that CAFs can modulate various forms of regulated cell death (RCD) in adjacent tumor cells, thus involving cancer proliferation, therapy resistance, and immune exclusion. Here, we present a brief introduction to CAFs and basic knowledge of RCD, including apoptosis, autophagy, ferroptosis, and pyroptosis.

Targeting pyroptosis in breast cancer: biological functions and therapeutic potentials on It.

Pyroptosis is a lytic and inflammatory type of programmed cell death that is mediated by Gasdermin proteins (GSDMs). Attractively, recent evidence indicates that pyroptosis involves in the development of tumors and can serve as a new strategy for cancer treatment. Here, we present a basic knowledge of pyroptosis, and an overview of the expression patterns and roles of GSDMs in breast cancer.

Neobavaisoflavone inhibits antitumor immunosuppression via myeloid-derived suppressor cells.

Neobavaisoflavone (Neo), as a traditional Chinese medicine, is the active ingredient in the herb Psoralea corylifolial and has antitumor activity. Myeloid-derived suppressor cells (MDSCs), which are a heterogeneous population of haematopoietic cells of the myeloid lineage, have been reported to be closely related to the pathogenesis of tumour progression, but whether Neo can regulate MDSC expansion and function remains unclear. Here, we found that Neo could inhibit the expansion and suppressive function of MDSCs by targeting STAT3.

Neobavaisoflavone-mediated T9 cell differentiation ameliorates bowel inflammation.

Neobavaisoflavone (Neo), is the active constituent of the herb Psoralea corylifolial, used in the traditional Chinese medicine, and has anti-inflammatory activity, but whether Neo could regulate colitis remains unclear. T helper 9 (T9) cells, a subset of CD4 T helper cells characterized by secretion of IL-9, have been reported to be involved in the pathogenesis of many autoimmune and inflammatory diseases, but whether Neo could control T9 cell differentiation also remains unclear. Here, we found that Neo could decrease IL-9 production of CD4 T cells by targeting PU.

Exosomes Derived from Mouse Adipose-Derived Mesenchymal Stem Cells Alleviate Benzalkonium Chloride-Induced Mouse Dry Eye Model via Inhibiting NLRP3 Inflammasome.

Purpose: The objective of the study was to investigate efficacy and mechanisms of mouse adipose-derived mesenchymal stem cell-derived exosomes (mADSC-Exos) in the benzalkonium chloride (BAC)-induced mouse dry eye model.

Methods: Exosomes in the mADSC culture supernatant were isolated by ultracentrifugation. Western blotting, nanoparticle tracking analysis, and transmission electron microscopy were used to characterize mADSC-Exos.

Exenatide Twice Daily Plus Glargine Versus Aspart 70/30 Twice Daily in Patients With Type 2 Diabetes With Inadequate Glycemic Control on Premixed Human Insulin and Metformin.

Objective: Many patients with type 2 diabetes treated with premixed insulin gradually have inadequate glycemic control and switch to a basal-bolus regimen, which raises some concerns for weight gain and increased hypoglycemic risk. Switching to combination use of glp-1 agonist and basal insulin may be an alternative option.

Methods: After a 12-week premixed human insulin 70/30 dosage optimization period, 200 patients with HbA1c of 7.

Schisandrin B-mediated TH17 cell differentiation attenuates bowel inflammation.

Schisandrin B (Sch B) is the major active constituent of the traditional Chinese medicine Schisandra chinensis and has anti-inflammatory activity, but the target of Sch B remains unclear. T helper 17 (T17) cells have been involved in the pathogenesis of many autoimmune and inflammatory diseases. Here, we showed that Sch B could decrease IL-17A production of CD4 T cells by targeting STAT3 in vitro.

Astragaloside IV inhibits cell proliferation and metastasis of breast cancer via promoting the long noncoding RNA TRHDE-AS1.

Astragaloside IV (ASV), which has several pharmacological abilities, shows potential therapeutic effects on certain cancers by regulating the expression of long noncoding RNA (lncRNA). However, the anticancer role that ASV plays by regulating lncRNAs in breast cancer remains unknown. In this study, we first demonstrated that the lncRNA of TRHDE antisense RNA 1 (TRHDE-AS1) was downregulated in breast cancer tissues and cells.

Paclitaxel Promotes Tumor-Infiltrating Macrophages in Breast Cancer.

Objective: Breast cancer remains the most threatening triggers of cancer death in women. Drug resistance inevitably leads to the weakness of treatment for breast cancer. Macrophages, as one of the most abundant immune cells in tumor immune-infiltrating microenvironment, involves in cell survival, migration, and invasion of breast cancer.

A Unique Four-Point Approach for Removal of Giant Breast Fibroadenoma With Marked Asymmetry: A Modified Round Block Technique.

The removal of the giant breast fibroadenoma (GFA) with esthetic repair of the severe deformed breast is a surgical challenge. This was a retrospective study of data of 10 patients with GFAs who treated with a modified round block technique at the Department of Breast Surgery, Hangzhou First People's Hospital (Hangzhou, Zhejiang province, China) from March 2014 to June 2017. Preoperatively, according to the degree of excess skin and asymmetry, a four-point approach was designed.
