BACKGROUND Glycosylphosphatidylinositol-specific phospholipase D (GPI-PLD) may play an important role in inflammation, because it can hydrolyze the GPI anchors of several inflammatory membrane proteins (eg, CD106, CD55, and CD59) and its hydrolytic products upregulate macrophage cytokine expression (eg, interleukin-1 and tumor necrosis factor-alpha). Because of its potential regulatory role in ...

OBJECTIVE This study aimed to evaluate the efficacy and safety of pegylated liposomal doxorubicin (PLD) with or without carboplatin in Korean patients with recurrent ovarian cancer (ROC), fallopian tube, or primary peritoneal cancer. METHODS This retrospective study included 52 patients with ROC, fallopian tube, or primary peritoneal cancer who received PLD (50 mg/m2) between 1st December 201...

Phospholipase D (PLD) activity, as measured by the transphosphatidylation of cellular phospholipids, is elevated in BALB/c 3T3 cells transformed by v-Src. Phorbol esters that activate protein kinase C (PKC) also increase PLC activity in BALB/c 3T3 cells. v-Src-induced PLD activity could be distinguished from phorbol ester-induced PLD activity by differential radiolabelling of phospholipids, whi...

BACKGROUND Ovarian cancer (OC) is the sixth most common cancer in women. Currently, carboplatin/paclitaxel ± bevacizumab is the cornerstone of front-line treatment. Conversely, the therapeutic options for recurrent or progressive disease are not well defined. For platinum-sensitive patients the best therapeutic approach is still a re-challenge with a platinum-based regimen. Pegylated liposomal ...

The 5-HT2A receptor (5-HT2AR) is implicated in psychotropic changes within the central nervous system (CNS). A number of polymorphisms have been reported in the 5-HT2AR gene; one of these results in a non-synonymous change, H452Y, in the carboxy-terminal tail of the receptor protein. The minor allele (9% occurrence) has been statistically associated with CNS dysfunction such as impaired memory ...

Membrane disruption has been proposed to be a key event in plant senescence, and phospholipase D (PLD; EC 3.1.4.4) has been thought to play an important role in membrane deterioration. We recently cloned and biochemically characterized three different PLDs from Arabidopsis. In this study, we investigated the role of the most prevalent phospholipid-hydrolyzing enzyme, PLD alpha, in membrane degr...

Phospholipid signaling mediated by lipid-derived second messengers or biologically active lipids is still new and is not well established in plants. We recently have found that lysophosphatidylethanolamine (LPE), a naturally occurring lipid, retards senescence of leaves, flowers, and postharvest fruits. Phospholipase D (PLD) has been suggested as a key enzyme in mediating the degradation of mem...

Drug-induced phospholipidosis (PLD) is a lysosomal storage disorder characterized by the accumulation of phospholipids within the lysosome. This adverse drug effect can occur in various tissues and is suspected to impact cellular viability. Therefore, it is important to test chemical compounds for their potential to induce PLD during the drug design process. PLD has been reported to be a side e...

Phospholipase D (PLD) hydrolyzes membrane lipids to generate phosphatidic acid (PA) and a free-head group (Fig. 1), and this activity is widespread in plants. Recent results indicate that PLD plays multiple regulatory roles in diverse plant processes, including abscisic acid (ABA) signaling, programmed cell death, root hair patterning, root growth, freezing tolerance, and other stress responses...

BACKGROUND We hypothesized that a response to pegylated liposomal doxorubicin (PLD, Caelyx/Doxil) followed by maintenance is beneficial and safe in recurrent ovarian cancer. PATIENTS AND METHODS Sixteen patients have received PLD for more than 1 year for recurrent ovarian (14) or fallopian tube (2) cancer. All had stable disease or better responses to PLD + carboplatin (5) or topotecan (9) do...
