Aim. Cancer continues to pose a serious threat human health. Euphorbia plants are rich in phenolics, aromatic esters, steroids and several bioactive compounds. Studies have shown the presence of large number compounds E. echinus including flavonoids, proanthocyanins. Method. There it was investigated cytotoxic effects methanolic extract on K562, HL60, Ishikawa, Raji SH-SY5Y cells. Results. The ...

We studied the maternally inherited chloroplast DNA polymorphism at three microsatellite loci of 157 Quercus robur trees from 38 native populations in Lithuania. found high diversity eight haplotypes Balkan lineage A (frequency 0.75) and “German” subbranch (freq. 0.12), western eastern Italian lineages C 0.05 0.06, respectively), Iberian B 0.03). The were geographically well structured (among p...

Cancer cell engraftment in the target organ is necessary to establish metastasis. Clinically, lymph node metastasis of single cells has been confirmed using cytokeratin staining. In the current study, a LacZ-labeled cancer cell line was used to visualize intrahepatic metastasis of single cells or liver micrometastasis. KM12SM-lacZ stably expressing LacZ was prepared with a highly metastatic col...

The association of glucokinase with insulin secretory granules has been shown by cell microscopy techniques. We used MIN6 insulin-secretory cells and organelle fractionation to determine the effects of glucose on the subcellular distribution of glucokinase. After permeabilization with digitonin, 50% of total glucokinase remained bound intracellularly, while 30% was associated with the 13,000g p...

Ovarian carcinoma (OC) is the most lethal gynecological malignancy. Despite the advances in the treatment of OC with combinatorial regimens, including surgery and platinum-based chemotherapy, patients generally exhibit poor prognosis due to high chemotherapy resistance. Herein, we tested the hypothesis that DNA damage response (DDR) pathways are involved in resistance of OC patients to platinum...

The higher-order organization of chromatin is well-established, with chromosomes occupying distinct positions within the interphase nucleus. Chromatin is susceptible to, and constantly assaulted by both endogenous and exogenous threats. However, the effects of DNA damage on the spatial topology of chromosomes are hitherto, poorly understood. This study investigates the organization of all 24 hu...

DNA damage triggers a phosphorylation-based signaling cascade known as the DNA damage response. p19INK4d, a member of the INK4 family of CDK4/6 inhibitors, has been reported to participate in the DNA damage response promoting DNA repair and cell survival. Here, we provide mechanistic insight into the activation mechanism of p19INK4d linked to the response to DNA damage. Results showed that p19I...
