Tumor infiltrating neutrophil might play a major role in predicting the clinical outcome of breast cancer patients treated with neoadjuvant chemotherapy.

Background: This study was aimed to explore the predictive ability of tumor infiltrating neutrophil (TIN) in patients with breast cancer treated with neoadjuvant chemotherapy (NACT). Furthermore, the significance of TIN's dynamic change before and after NACT was investigated.

Methods: Between January 2004 and December 2017, a total of 133 patients with breast cancer who underwent NACT before surgery were enrolled in this retrospective cohort.

Developing new targeting strategy for androgen receptor variants in castration resistant prostate cancer.

The presence of androgen receptor variant 7 (AR-V7) variants becomes a significant hallmark of castration-resistant prostate cancer (CRPC) relapsed from hormonal therapy and is associated with poor survival of CRPC patients because of lacking a ligand-binding domain. Currently, it still lacks an effective agent to target AR-V7 or AR-Vs in general. Here, we showed that a novel class of agents (thailanstatins, TSTs and spliceostatin A analogs) can significantly suppress the expression of AR-V7 mRNA and protein but in a less extent on the full-length AR expression.

The ubiquitin ligase TRIM25 targets ERG for degradation in prostate cancer.

Ets related gene (ERG) is a transcription factor that is overexpressed in 40% of prostate tumors due to a gene fusion between ERG and TMPRSS2. Because ERG functions as a driver of prostate carcinogenesis, understanding the mechanisms that influence its turnover may provide new molecular handles to target the protein. Previously, we found that ERG undergoes ubiquitination and then is deubiquitinated by USP9X in prostate cancer cells to prevent its proteasomal degradation.

Breast Tumor Kinase (Brk/PTK6) Is Induced by HIF, Glucocorticoid Receptor, and PELP1-Mediated Stress Signaling in Triple-Negative Breast Cancer.

Cancer cells use stress response pathways to sustain their pathogenic behavior. In breast cancer, stress response-associated phenotypes are mediated by the breast tumor kinase, Brk (PTK6), via the hypoxia-inducible factors HIF-1α and HIF-2α. Given that glucocorticoid receptor (GR) is highly expressed in triple-negative breast cancer (TNBC), we investigated cross-talk between stress hormone-driven GR signaling and HIF-regulated physiologic stress.

KDM4/JMJD2 Histone Demethylase Inhibitors Block Prostate Tumor Growth by Suppressing the Expression of AR and BMYB-Regulated Genes.

Histone lysine demethylase KDM4/JMJD2s are overexpressed in many human tumors including prostate cancer (PCa). KDM4s are co-activators of androgen receptor (AR) and are thus potential therapeutic targets. Yet to date few KDM4 inhibitors that have anti-prostate tumor activity in vivo have been developed.

Alternative surgical strategies in patients with sporadic medullary thyroid carcinoma: Long-term follow-up.

The extent of surgical resection in patients with sporadic medullary thyroid carcinoma (SMTC) remains controversial. The aim of the present study was to discuss the prognosis of sporadic medullary thyroid carcinoma with different surgical treatments. Of 73 patients with SMTC (mean age of 43.

[Diagnosis and surgical treatment of Castleman's disease].

Objective: To explore the clinical features and surgical treatment of tumors associated with Castleman's disease (CD).

Methods: The clinical profiles of 19 patients with neck giant lymph node hyperplasia were analyzed retrospectively. There were 8 males and 11 females with a median age of 40 years old (range: 7 - 74).

Susceptibility of Hep3B cells in different phases of cell cycle to tBid.

tBid is a pro-apoptotic molecule. Apoptosis inducers usually act in a cell cycle-specific fashion. The aim of this study was to elucidate whether effect of tBid on hepatocellular carcinoma (HCC) Hep3B cells was cell cycle phase specific.

[Clinical analysis on giant lymph node hyperplasia on neck].

Objective: To improve the diagnosis and management level of giant lymph node hyperplasia (Castleman's disease).

Methods: To retrospective analyze 10 misdiagnosed cases with Castleman's disease in order to give some suggestions for clinical diagnosis and differential diagnosis.

Results: Ten patients with neck giant lymph node hyperplasia underwent surgical treatment after misdiagnosis.

[Correlation of bacteria in the contaminated drug and the environmental microbes in the clean room for pharmaceutical microbial test investigated by FTIR].

The FTIR method was used to investigate the correlation of bacteria in the contaminated drug and the environmental microbes in the clean room for pharmaceutical microbial test. The similarity of bacteria in the contaminated drug and environmental microbes was compared by critical hit value method and cluster analysis method. This constructed the FTIR spectra library of clean room environmental microbe, and determined the criterion to promptly judge if the bacteria isolated from pharmaceuticals were contaminated by environment or not, hence the exactness of "one-off report" of sterile test result can be guaranteed, and can be used for the dynamic monitoring of environmental bacteria of clean room.

Plasmodium yoelii: influence of antimalarial treatment on acquisition of immunity in BALB/c and DBA/2 mice.

The effect of antimalarial drugs on immune responses to the malaria infection is evaluated in vivo using two experimental self-cured rodent models. BALB/c and DBA/2 mice were infected by Plasmodium yoelii 17XNL and 17XL strains, respectively, and then treated with different doses of antimalarial drugs: chloroquine (228mg/kg or 114mg/kg of the body weight) or artesunate (78mg/kg or 39mg/kg). The effect of antimalarial drugs on host immune responses was evaluated by parasitemia, splenocyte IFN-gamma production level, and parasite-specific IgG level in the serum, however, no significant differences were observed between drug-treated and untreated groups.

Plasmodium yoelii: distinct CD4(+)CD25(+) regulatory T cell responses during the early stages of infection in susceptible and resistant mice.

The outcome of experimental murine infection with different strains of malaria parasites, ranging from spontaneous cure to death, depends largely on the establishment of effective Th1 responses during the early stages of infection. Here we describe the disparity in CD4(+)CD25(+) regulatory T cell (Treg) responses during the early stages of infection with the highly virulent Plasmodium yoelii 17XL strain in susceptible (BALB/c) and resistant (DBA/2) mice. An increased proportion of Tregs 3-4 days post inoculation, co-occurring with elevated IL-10 levels, is observed in BALB/c but not in DBA/2 mice.
