RNF126 suppresses amino acid-mediated mTORC1 signaling pathway by ubiquitinating ILF3 in HEK293T cells.

The mammalian Target of Rapamycin Complex 1 (mTORC1) serves as a metabolic hub that integrates external nutrients to promote cell growth and metabolism, with its activation closely associated with accelerated cancer progression. Interleukin enhancer-binding factor 3 (ILF3) has been identified as a negative regulator of mTORC1 by tethering GATOR1/2 to the lysosomal membrane during amino acid sensing. However, the regulatory mechanisms of the ILF3-mediated mTORC1 signaling pathway remain unclear.

MARCH1 negatively regulates TBK1-mTOR signaling pathway by ubiquitinating TBK1.

Background: TBK1 positively regulates the growth factor-mediated mTOR signaling pathway by phosphorylating mTOR. However, it remains unclear how the TBK1-mTOR signaling pathway is regulated. Considering that STING not only interacts with TBK1 but also with MARCH1, we speculated that MARCH1 might regulate the mTOR signaling pathway by targeting TBK1.

SPOP negatively regulates mTORC1 activity by ubiquitinating Sec13.

The mammalian target of rapamycin complex1 (mTORC1) can response to amino acid to regulate metabolism and cell growth. GATOR2 act as important role in amino acid mediated mTORC1 signaling pathway by repressing GTPase activity (GAP) of GATOR1. However, it is still unclear how GATOR2 regulates mTORC1 signaling pathway.

WFDC21P promotes triple-negative breast cancer proliferation and migration through WFDC21P/miR-628/SMAD3 axis.

Long non-coding RNAs (lncRNAs) modulate cell proliferation, cycle, and apoptosis. However, the role of lncRNA-WFDC21P in the tumorigenesis of triple-negative breast cancer (TNBC) remains unclear. Results of this study demonstrated that WFDC21P levels significantly increased in TNBC, which was associated with the poor survival of patients.

Activation of C3 and C5 May Be Involved in the Inflammatory Progression of PCM and GM.

Plasma cell mastitis (PCM) and granulomatous mastitis (GM) are the most common inflammatory diseases constituting nonbacterial mastitis (NBM). However, the pathogenesis of NBM remains unclear. In this study, risk factors for NBM were assessed, as well as the pathological features of PCM and GM.

Relationship Between Lifestyle Habits and Health-Related Quality of Life of Recently Diagnosed Breast Cancer Patients: A Comparison Between Younger and Older Women in China.

The aim of this study was to evaluate the relationship between lifestyle habits and health-related quality of life (HRQoL) among different ages who were initially diagnosed with breast cancer (within the first 2 weeks) and to determine the contribution of lifestyle habits factors on HRQoL. Patients with breast cancer were recruited from 22 hospitals in 11 provinces or municipalities in northern and eastern China. The Functional Assessment of Cancer Therapy-Breast Cancer (FACT-B) was used to measure HRQoL.

A novel and effective approach to generate germline-like monoclonal antibodies by integration of phage and mammalian cell display platforms.

Phage display technology allows for rapid selection of antibodies from the large repertoire of human antibody fragments displayed on phages. However, antibody fragments should be converted to IgG for biological characterizations and affinity of antibodies obtained from phage display library is frequently not sufficient for efficient use in clinical settings. Here, we describe a new approach that combines phage and mammalian cell display, enabling simultaneous affinity screening of full-length IgG antibodies.

XRCC5/6 polymorphisms and their interactions with smoking, alcohol consumption, and sleep satisfaction in breast cancer risk: A Chinese multi-center study.

Background: X-ray repair cross-complementary 5 (XRCC5) and 6 (XRCC6) are critical for DNA repair. Few studies have assessed their association with breast cancer risk, and related gene-environment interactions remain poorly understood. This study aimed to determine the influence of XRCC5/6 polymorphisms on breast cancer risk, and their interactions with cigarette smoking, alcohol consumption, and sleep satisfaction.

Using KISS Flaps in a Chest Wall Reconstruction After Mastectomy for Locally Advanced Breast Cancer: A New Technique.

This study described a technique for the reconstruction of large lateral thoracic defects after local advanced breast cancer resection that allows for complete cover of the defect and primary closure of the donor site. The authors performed reconstruction using the newly designed KISS flap in 2 women for coverage of their large skin defect (15 × 13 cm each) following mastectomies with extensive tissue resection. The KISS flap consisting of 2 skin islands (marked Flap A and Flap B; 15 × 6 cm each) was designed and transferred to the thoracic defect through the subcutaneous tunnel, and based on the same vessel.

Enhanced nitrogen and carbon removal performance of simultaneous ANAMMOX and denitrification (SAD) process with trehalose addition treating saline wastewater was investigated in a sequencing batch reactor (SBR). The optimal nitrogen removal was achieved at 0.25 mmol·L trehalose, during which NH-N, NO-N, NO-N, and COD could be completely removed.

Single-incision surgery for gynecomastia using TriPort: A case report.

Gynecomastia is a common benign condition of the male breast, frequently observed in newborns, adolescents and the elderly. Surgical excision remains one of the most effective methods for the management of patients with gynecomastia, particularly those with fibrosis or a course of >1 year. The present study describes two cases of patients with gynecomastia and presents a novel method of treatment, combining endoscopic surgery and liposuction using a TriPort, which may effectively remove breast tissue and shorten hospitalization time compared with a direct excision method.

[Enrichment and Nitrogen Removal Characteristics of Marine Anaerobic Ammonium Oxidizing Bacteria].

In this work, enrichment and nitrogen removal characteristics of marine anaerobic ammonium oxidizing bacteria were investigated by seeding sediment sludge from the Jiaozhou bay. Experimental results showed that the whole process could be divided into four phases:bacterial lysis phase (1-15 d), lag phase (16-152 d), exponential growth phase (153-183 d) and stationary phase (184-192 d). Compared to freshwater anaerobic ammonium oxidizing bacteria, the lag phase (137 d) was longer.

A matched case-control study involving 1489 patients with breast cancer and 1489 controls was conducted across 21 hospitals in 11 provinces in China, from April 2012 to April 2013. We developed a structured questionnaire to record information from face-to-face interviews with participants.

Crystal structure-based comparison of two NAMPT inhibitors.

Inhibition of nicotinamide phosphoribosyltransferase (NAMPT) is a novel strategy for cancer therapy, but only two inhibitors of NAMPT (FK866 and CHS828) have progressed into clinical trials. This study seeks to compare a novel potent NAMPT inhibitor, MS0, with a classical inhibitor FK866 in their biological activity and molecular binding mode, thereby contributing to future chemical optimization and a further understanding of the action mode of NAMPT inhibitors. The IC values of MS0 and FK866 in inhibition of recombinant human NAMPT activity were 9.

Circulating High-Molecular-Weight (HMW) Adiponectin Level Is Related with Breast Cancer Risk Better than Total Adiponectin: A Case-Control Study.

The level of total adiponectin, a mixture of different adiponectin forms, has been reported associated with breast cancer risk with inconsistent results. Whether the different forms play different roles in breast cancer risk prediction is unclear. To examine this, we measured total and high molecular weight (HMW) adiponectin in a case-control study (1167 sets).

Effect of bFGF on the MCF-7 Cell Cycle with CD44(+)/CD24(-): Promoting the G0/G1→G2/S Transition.

Purpose: Few cells with stem cell characteristics possess capabilities of self-renewal and differentiation, which leads to high tumorigenesis and resistance to standard chemotherapeutic agents. These cells are mostly quiescent, and arrest occurs at the mitotic G0/G1 phase in mitosis. We explored the effects of basic fibroblast growth factor (bFGF) on the MCF-7 cell cycle with CD44(+)/CD24(-).

Background: Important advances have made within the past few years in the treatment of hepatocellular carcinoma (HCC), however, the long-term prognosis after resection of HCC remains unsatisfactory as a result of a high incidence of recurrence. This study was to investigate immunization with fusions of DCs and HCC cells against HCC tumors transplanted to mice.

Methods: Fusion cells of dendritic cells (DCs) and H22 cells were prepared with polyethylene glycol.

What has luck got to do with economic development? An interpretation of resurgent Asia's growth experience.

This paper critically reexamines the belief, currently gathering strength in the literature, that economic development depends on good luck rather than on good policy, and that Prometheus is "unchained by chance". While it is impossible to disprove the role of luck in growth, we argue that luck is endogenous, and good luck is a function of good policy. Luck favours those who strive.
