Methods: Seven databases were searched from the time of database establishment to 31 March 2022. Randomized Controlled Trials (RCTs) on acupuncture intervention for CRI were collected.

Immediate surgical mesh-free implant-based breast reconstruction with fascial flap in breast cancer patients after mastectomy.

Purpose: Surgical meshes are often used in retro-pectoral implant-based breast reconstruction (IBBR) to improve lower pole expansion. However, using of surgical meshes is associated with increased complications and costs. To solve this problem, we have adopted a modified fascia-based IBBR technique using fasciae of pectoral major, serratus anterior, and external oblique muscles to form a sling covering the lower pole of prosthesis since 2014.

Toll-like receptor 3 -926T>A increased the risk of breast cancer through decreased transcriptional activity.

Toll-like receptor 3 (TLR3) is a viral sensor that induces apoptosis in response to double-stranded RNA (dsRNA). Common genetic changes in the TLR3 gene may influence breast cancer susceptibility and development. However, all of the polymorphisms in the previous study were only markers of the TLR3 gene, not causative polymorphisms.

Identification of core genes and clinical roles in pregnancy-associated breast cancer based on integrated analysis of different microarray profile datasets.

More women are delaying child-birth. Thus, the diagnosis of pregnancy-associated breast cancer (PABC) will continue to increase. The aim of this study was to identify core candidate genes of PABC, and the relevance of the genes on the prognosis of PABC.

Toll-like receptor 3 acts as a suppressor gene in breast cancer initiation and progression: a two-stage association study and functional investigation.

Toll-like receptor 3 (TLR3) is a receptor recognizing double-stranded RNA (dsRNA) from viruses as well as from lytic mammalian cells. In the present study, we performed a two-stage association study (n = 3,551) and found that the minor alleles of two SNPs (the T-allele of rs5743312 and the T-allele of rs3775296) conferred increased risks of breast cancer incidence. The adjusted odds ratios (ORs) were 2.

Estrogen receptor-α-miR-1271-SNAI2 feedback loop regulates transforming growth factor-β-induced breast cancer progression.

Background: Breast cancer is the most common cancer among women worldwide, and approximately 70% of breast cancers are hormone receptor-positive and express estrogen receptor-α (ERα) or/and progesterone receptor. ERα has been identified to promote the growth of primary breast cancer, however, it can also antagonize signaling pathways that lead to epithelial-mesenchymal transition (EMT), including transforming growth factor-β (TGF-β) signaling. miRNA alteration or dysfunction is involved in cancer development and progression.

Effect of genetic variants in two chemokine decoy receptor genes, DARC and CCBP2, on metastatic potential of breast cancer.

The inhibitory effect of two chemokine decoy receptors (CDRs), DARC and D6, on breast cancer metastasis is mainly due to their ability to sequester pro-malignant chemokines. We hypothesized that genetic variants in the DARC and CCBP2 (encoding D6) genes may be associated with breast cancer progression. In the present study, we evaluated the genetic contributions of DARC and CCBP2 to metastatic potential, indicated by lymph node metastasis (LNM).

Germline genetic variants disturbing the Let-7/LIN28 double-negative feedback loop alter breast cancer susceptibility.

Previous studies have shown that let-7 can repress the post-transcriptional translation of LIN28, and LIN28 in turn could block the maturation of let-7, forming a double-negative feedback loop. In this study, we investigated the effect of germline genetic variants on regulation of the homeostasis of the let-7/LIN28 loop and breast cancer risk. We initially demonstrated that the T/C variants of rs3811463, a single nucleotide polymorphism (SNP) located near the let-7 binding site in LIN28, could lead to differential regulation of LIN28 by let-7.

The chemokine receptor CCR4 promotes tumor growth and lung metastasis in breast cancer.

Increasing evidence has shown that chemokines and chemokine receptors are associated with tumor growth and metastasis. CCR4, an important chemokine receptor for regulating immune homeostasis, is thought to be involved in hematologic malignancies and has also recently implicated in some solid tumors, such as gastric cancer. The possible role of CCR4 in breast cancer has not been well elucidated.

The associations between two polymorphisms in the interleukin-10 gene promoter and breast cancer risk.

The association between single-nucleotide polymorphisms (SNPs) in the interleukin-10 (IL-10) gene promoter and breast cancer risk is still ambiguous. We here performed a meta-analysis based on the evidence currently available from the literature to make a more precise estimation of the relationship between two genetic variants in the IL-10 gene promoter, -1082A > G (rs1800896) and -592C > A (rs1800872), and breast cancer. Odds ratios (ORs) with 95% confidence intervals (CIs) were used to assess the corresponding strengths of association under the codominant, dominant, and recessive models.

RAD51 135G>C does not modify breast cancer risk in non-BRCA1/2 mutation carriers: evidence from a meta-analysis of 12 studies.

A single-nucleotide polymorphism (SNP) in the 5'-untranslated region (UTR) of RAD51, 135G>C (rs1801320), was reported to be associated with an increased risk of breast cancer among BRCA2 as well as BRCA1 carriers. A few studies have also investigated the genetic contribution of RAD51 135G>C to the risk of sporadic breast cancers or breast cancer in non-BRCA1/2 carriers, though the results are yet controversial and inconclusive. We, in this study, performed a more precise estimation of the relationship between 135G>C and breast cancer among non-BRCA1/2 mutation carriers by meta-analyzing the currently available evidence from the literature.

A systematic review of the relationship between polymorphic sites in the estrogen receptor-beta (ESR2) gene and breast cancer risk.

The estrogen signal is mediated by the estrogen receptor (ER). The specific role of ER-beta, a second ER, in breast carcinogenesis is not known. A number of association studies have been carried out to investigate the relationship between polymorphic sites in the ESR2 gene and breast cancer risk, however, the results are inconsistent.

XRCC2 Arg188His polymorphism is not directly associated with breast cancer risk: evidence from 37,369 subjects.

Several common single-nucleotide polymorphisms (SNPs) within the XRCC2 gene have been identified as potential breast cancer susceptibility loci and a coding SNP in exon 3 (Arg188His, rs3218536) has been extensively studied, though the results were inconclusive. We, in this study, performed a more convincing and precise estimation of the relationship between Arg188His and breast cancer by meta-analyzing the currently available evidence from literature. A total of 16 studies involving 18,341 cases and 19,028 controls (37,369 subjects) were identified for meta-analysis.

No association between a progesterone receptor gene promoter polymorphism (+331G>A) and breast cancer risk in Caucasian women: evidence from a literature-based meta-analysis.

Sex steroid hormones and their receptors such as estrogen receptor (ER) and progesterone receptor (PgR) have been widely studied for their roles in the etiology of breast cancer. To date, many studies have evaluated the association between a functional polymorphism in the PgR gene promoter (+331G>A, rs10895068) and breast cancer risk; however, the result is still ambiguous and inconclusive. In order to derive a more precise estimation of the association, a meta-analysis was performed in this study.

Lack of an association between a functional polymorphism in the interleukin-6 gene promoter and breast cancer risk: a meta-analysis involving 25,703 subjects.

The association between a single-nucleotide polymorphism (SNP) -174G > C (rs1800795) located in the IL-6 gene promoter and breast cancer risk is still controversial and ambiguous. We performed in this study a more precise estimation of the relationship by meta-analyzing the currently available evidence from literature. A total of 11 publications containing 12 studies including 10,137 cases and 15,566 controls were identified.

Current evidence on the relationship between polymorphisms in the COX-2 gene and breast cancer risk: a meta-analysis.

The association between single-nucleotide polymorphisms (SNPs) in the COX-2 gene and breast cancer risk is still ambiguous. We here try to derive a more precise estimation of the relationship by performing a meta-analysis based on currently available evidence from literature. More than 15 SNPs have been studied, and the most studied genetic variants were rs5275, rs5277, and rs20417.
