SATB1 and p16 Expression and Prognostic Value in Croatian Hodgkin Lymphoma Patients: A Unicentric Study.

Hodgkin lymphoma (HL) is a rare lymphoid neoplasm in which Hodgkin/Reed-Stenberg (HRS) cells are admixed with a population of non-neoplastic inflammatory cells and fibrosis. Dysregulated expressions of cell cycle regulators and transcription factors have been proven as one of the hallmarks of HL. In that context, SATB1 and p16 have been reported as potential regulators of HL progression and survival.

Dietary Habits in Patients with Systemic Lupus Erythematosus.

Patients with systemic lupus erythematosus (SLE) are often interested in which diets to follow. Our aim was to investigate which dietary habits were common among our patients, and which of them were in correlation with laboratory parameters of disease activity, such as complement values and 24-h proteinuria. This study included 76 patients with SLE in clinical remission with a 6-month flare free period.

Higher AURKA and PLK1 expression are associated with inferior overall survival in patients with myelofibrosis.

Aurora-kinase-A (AURKA), BORA and Polo-like-kinase-1 (PLK1) are regulating cell-cycle control and promotion of mitosis entry. AURKA contributes to Janus-kinase-2 (JAK2) activation and increased AURKA protein levels were reported in CD34+ and CD41+ cells of myeloproliferative neoplasm patients, leading to aneuploidy and aberrant megakaryopoiesis. We aimed to investigate AURKA, BORA and PLK1 mRNA expression in unfractionated bone-marrow aspirates of 43 patients with myelofibrosis (28 primary-/PMF, 15 secondary-myelofibrosis/SMF) and 12 controls and to assess their clinical correlations.

Penetrating the air-liquid interface is the key to colonization and wrinkly spreader fitness.

In radiating populations of SBW25, adaptive wrinkly spreader (WS) mutants are able to gain access to the air-liquid (A-L) interface of static liquid microcosms and achieve a significant competitive fitness advantage over other non-biofilm-forming competitors. Aerotaxis and flagella-based swimming allows SBW25 cells to move into the high-O region located at the top of the liquid column and maintain their position by countering the effects of random cell diffusion, convection and disturbance (i.e.

The RNA helicase UPF1 associates with mRNAs co-transcriptionally and is required for the release of mRNAs from gene loci.

UPF1 is an RNA helicase that is required for nonsense-mediated mRNA decay (NMD) in eukaryotes, and the predominant view is that UPF1 mainly operates on the 3'UTRs of mRNAs that are directed for NMD in the cytoplasm. Here we offer evidence, obtained from , that UPF1 constantly moves between the nucleus and cytoplasm by a mechanism that requires its RNA helicase activity. UPF1 is associated, genome-wide, with nascent RNAs at most of the active Pol II transcription sites and at some Pol III-transcribed genes, as demonstrated microscopically on the polytene chromosomes of salivary glands and by ChIP-seq analysis in S2 cells.

A novel form of JARID2 is required for differentiation in lineage-committed cells.

Polycomb repressive complex-2 (PRC2) is a group of proteins that play an important role during development and in cell differentiation. PRC2 is a histone-modifying complex that catalyses methylation of lysine 27 of histone H3 (H3K27me3) at differentiation genes leading to their transcriptional repression. JARID2 is a co-factor of PRC2 and is important for targeting PRC2 to chromatin.

Targeting autophagy to modulate cell survival: a comparative analysis in cancer, normal and embryonic cells.

Autophagy is linked to multiple cancer-related signaling pathways, and represents a defense mechanism for cancer cells under therapeutic stress. The crosstalk between apoptosis and autophagy is essential for both tumorigenesis and embryonic development. We studied the influence of autophagy on cell survival in pro-apoptotic conditions induced by anticancer drugs in three model systems: human cancer cells (NCI-H460, COR-L23 and U87), human normal cells (HaCaT and MRC-5) and zebrafish embryos (Danio rerio).

The Meaning of NMD: Translate or Perish.

Premature translation termination leads to a reduced mRNA level in all types of organisms. In eukaryotes, the phenomenon is known as nonsense-mediated mRNA decay (NMD). This is commonly regarded as the output of a specific surveillance and destruction mechanism that is activated by the presence of a premature translation termination codon (PTC) in an atypical sequence context.

Esterase and peroxidase isoforms in different stages of morphogenesis in Fritillaria meleagris L. in bulb-scale culture.

Morphogenesis in vitro is a complex and still poorly defined process. We investigated esterase and peroxidase isoforms detected in bulb scale, during Fritillaria meleagris morphogenesis. Bulbs were grown either at 4 °C or on a medium with an increased concentration of sucrose (4.

Liver metastases from breast cancer. Results of surgical resection.

Background/aims: Purpose of this study is to define the effectiveness of surgical resection of liver metastases from operated breast cancer.

Methodology: Nineteen patients underwent surgical exploration to resect liver metastases from previously operated breast carcinoma. Seventeen patients were resected: 15 patients had unique metastases and were submitted to a wedge liver resection while 2 had multiple lesions; in these cases a V-VI segmentectomy and a right hepatectomy was required.

[Anatomico-surgical contribution to the knowledge of the lymphatic spread of gastric adenocarcinoma].

Following the researches performed on lymphatic spread of gastric carcinoma, our study aimed to add useful informations to establish the extension of exeresis with radical intent on the basis of recent studies on sentinel node mapping. The study includes 120 consecutive cases of gastric cancer operated between 1996 and 2000. Sixty-nine (57.
