Abstract
A large number of studies have investigated possible drug resistance mechanisms of cancer cells and suggested strategies to overcome it. In this review, we outline the role and function of aldehyde dehydrogenase (ALDH) activity in multiple cellular functions and in cancer stem cells (CSCs) and focus on the role of retinoic acid (RA), one of the products of ALDH isozymes. We discuss our observation that ATRA and other RAs can suppress ALDH activity and decrease different ALDH isozyme proteins and result in detrimental effects on cell proliferation, invasion and chemotherapy sensitivity. We review the known uses of different RAs in the treatment of cancers. We review the use of RAs in combination with chemo-/radiotherapy and the major signaling pathways affected in different tumor types. We provide follow-up on studies that may have used our prior observation with the aim of targeting the CSCs. We conclude with summary of the findings and potential impact of published studies on future use of RAs in the targeting of CSCs and drug resistance.

Abstract
We used the morphoproteomic approach to analyze clear cell sarcoma of kidney (CCSK), a rare pediatric renal tumor, for which the exact pathogenesis and reliable diagnostic markers remain inexplicable. The tumor, currently being treated with chemotherapy and radiation therapy before or after radical nephrectomy, has demonstrated improved survival rates after introduction of doxorubicin. Three cases of CCSK were studied. We attempted to decipher the possible pathological mechanisms involved in CCSK and to explore the therapeutic targets and plausible less-toxic chemotherapeutic agents. We propose that cyclin D1 may be a central molecule in the pathogenesis of CCSK, driven mainly by the sonic hedgehog and the nuclear factor-kappa B pathways and secondarily by the mammalian target of rapamycin complex mTORC2/PI3K/Akt pathway, heat shock protein 90, and possibly phospholipase D1. Inclusion of relatively less toxic but effective therapies in the form of statins, 13-cis retinoic acid, curcumin, and 17-AAG in the combinatorial treatment strategies, which can target the involved subcellular pathways, may be considered.

Abstract
13-Cis-retinoic acid (13-cis-RA) causes depression-related behavior in mice. Hypothalamic dysregulation has been implicated in clinical depression. In fact, apoptosis of hypothalamic neurons may lead to depression after myocardial infarction. Our objective was to determine if 13-cis-RA affects cultured hypothalamic cell number. Treatment of GT1-7 hypothalamic cells with 10μM 13-cis-RA for 48h decreased cell growth to 45.6±13% of control. To determine if this decrease in cell number was due to 13-cis-RA acting as an oxidant, cells were treated with 13-cis-RA and ascorbic acid or butylated hydroxyanisole (BHA) for 24 or 48h. Neither antioxidant alleviated the inhibitory affects of 13-cis-RA. In addition, 13-cis-RA treatment did not increase superoxide anion production, indicating 13-cis-RA was not acting as an oxidant. To determine if 13-cis-RA was acting via retinoic acid receptors (RARs) to decrease cell number, GT1-7 cells were treated with 13-cis-RA and the RAR pan-antagonist, AGN 193109. Treatment with the RAR-antagonist blocked the ability of 13-cis-RA to decrease cell number, indicating this phenomenon was a RAR-independent mechanism. We hypothesize that the ability of 13-cis-RA to decrease hypothalamic cell number may contribute to the increased depression-related behaviors observed in mice.

Abstract
All-trans retinoic acid (ATRA) is a natural oxidative metabolite of Vitamin A (retinol) and is known to be a regulator of cell proliferation differentiation, especially in various malignant cells. The cyto-differentiating action of ATRA has led to its usage in the treatment of several malignancies, particularly acute promyelocytic leukemia (APL). There have been many reports regarding the cell biological effects of ATRA on human myeloma cells and a few clinical trials. Most of these reports have revealed growth inhibition by ATRA mediated by down-regulation of the IL-6/IL-6R auto/paracrine loop, and upregulation of p21/Cip1. Here, we review previous reports and introduce experimental results obtained using various myeloma cell lines established in our laboratory.

Abstract
This article emphasizes both the morphologic and phenotypic features of the bone marrow in plasma cell myeloma. It details the morphologic features of both trephine biopsies and marrow aspirations. It emphasizes the salient phenotypic features of marrow myeloma cells, in contrast with normal plasma cells. The myeloma cell phenotype is discussed from the perspective of both tissue section immunohistochemistry (IHC) and flow cytometry (FACS analysis). The specific criteria for myeloma diagnosis are discussed and illustrated in Figures 1-12. Finally, the emphasis is on the key morphologic and phenotypic diagnostic criteria of each of the plasma cell neoplasms.

Abstract
Increased cell volume, accumulation of lipid droplets in the cytoplasm, and nuclear degeneration are phenomena indicating terminal differentiation of human sebocytes followed by holocrine secretion and cell death. The molecular pathways of natural and induced sebocyte elimination are still unknown, however. In this study, SZ95 sebocytes were found to exhibit DNA fragmentation after a 6 h culture followed by increased lactate dehydrogenase release after 24 h, indicating cell damage. With the help of morphologic studies and using Oil Red detection of cellular lipids, cell enlargement, accumulation of lipid droplets in the cytoplasm, and nuclear fragmentation could be observed under treatment with arachidonic acid. Staurosporine, a potent inhibitor of phospholipid Ca2+-dependent protein kinase, increased externalized phosphatidylserine levels on SZ95 sebocytes, detected by annexin V/propidium iodide flow cytometry, as early as after 1 h, whereas dose-dependent reduction of bcl-2 mRNA and protein expression, enhanced DNA fragmentation, and increased caspase 3 levels, detected by caspase 3 inhibitor/propidium iodide flow cytometry, were found after 6 h of treatment. SZ95 sebocyte death was detected as early as after 6 h of SZ95 sebocyte treatment with high staurosporine concentrations (10(-6)-10(-5) M). 5Alpha-dihydrotestosterone (10(-8)-10(-5) M) did not affect externalized phosphatidylserine levels and DNA fragmentation in SZ95 sebocytes but slightly decreased lactate dehydrogenase cell release. Neither acitretin nor 13-cis retinoic acid (10(-8)-10(-5) M) affected externalized phosphatidylserine levels, DNA fragmentation, and lactate dehydrogenase cell release, despite the increased caspase 3 levels under treatment with 13-cis retinoic acid. The combined staurosporine and 13-cis retinoic acid treatment enhanced DNA fragmentation in SZ95 sebocytes to the same magnitude as in cells only treated with staurosporine. In conclusion, SZ95 sebocytes in vitro undergo apoptosis, which can be enhanced by the terminal differentiation inductor arachidonic acid or by staurosporine and leads to cell death. 5Alpha-dihydrotestosterone inhibits SZ95 sebocyte death without involving apoptotic pathways, and retinoids did not affect the programmed death of human sebocytes. The latter result fits well with the currently reported inability of normal skin cells to undergo apoptosis after treatment with retinoids, in contrast to their malignant counterparts.

Abstract
In the present study, the effects of 9-cis retinoic acid (RA) and 13-cis RA on acute myeloblastic leukaemia (AML) cell growth and the induction of apoptosis as well as its relationship with bcl-2 and p53 were compared with those of all-trans RA (ATRA). The study was performed with the subclones of the retinoid-sensitive OCI/AML-2 cell line. The most prominent inhibitory effect on clonogenic cell growth and morphological apoptosis was shown by 9-cis RA. In addition, Western blotting revealed the most obvious translocation of p53 from cytosol to nucleus in the case of 9-cis RA, which was the only retinoid able to change the conformation of p53 from mutational to wild type, as demonstrated by flow cytometry. There was no difference between the retinoids in the downregulation of bcl-2 as analysed by Western blotting and flow cytometry. The RA receptor (RAR)-alpha antagonist had no effect on apoptosis in any of the three retinoids studied using the annexin V method. In conclusion, this study shows that 9-cis RA was a more potent agent than ATRA or 13-cis RA in inducing growth arrest and apoptosis in the OCI/AML-2 subclones. The effect was associated with the downregulation of bcl-2 and was hardly mediated through the RAR-alpha receptor, but might be related to the activation of p53.

Abstract
UNLABELLED We evaluated the in vivo incidence of apoptosis and cell proliferation in multiple myeloma (MM) and investigated the correlation of both cellular events with histological tumour stage and grade, bcl-2 protein expression, serum IL-6 and sIL-6R. MATERIAL AND METHODS The TUNEL method was used to assess apoptosis and immunohistochemistry to assess the expression of proliferating cell nuclear antigen (PCNA) and bcl-2 protein in 30 bone marrow biopsy specimens. The apoptotic index (AI) and proliferative index (PI) were defined as the percentage of TUNEL and PCNA positive plasma cells, respectively. RESULTS The mean AI was 0.162% and the mean PI 27.44%. A positive correlation between AI and PI was found (r = 0.44, P = 0.017). PI was also correlated with tumour grade (P = 0.015). The mean bcl-2 protein expression was 70% and did not correlate with AI or PI, but was higher in specimens taken at first diagnosis than in specimens taken after response to treatment (P = 0.035). The mean serum IL-6 and sIL-6R values were 9.43 pg mL-1 and 47.27 ng mL-1, respectively. These parameters did not correlate with AI or PI. CONCLUSIONS The results indicate that MM might be among the malignancies with very low incidence of apoptosis. Proliferative activity increased in parallel with tumour histological grade. A positive correlation between apoptosis and proliferation was observed, but the incidence of these two cellular events seems not to be related to the bcl-2 protein expression and the serum levels of IL-6 and sIL-6R.

Abstract
Recently, it was disclosed that all-trans retinoic acid (ATRA) inhibits myeloma cell growth by downregulating the interleukin 6 (IL-6)/IL-6 receptor (IL-6R) auto/paracrine loop, and upregulating p21/Cip1 cyclin-dependent kinase inhibitor (CDK-I), thereby inducing apoptosis with a decrease in Bcl-2 protein expression. To elucidate and generalize the effects of ATRA on the proliferation and cellular biology of myeloma cells, 12 human myeloma cell lines established in our laboratory were utilized. Two out of the 12 lines showed enhanced growth on supplementation of ATRA and were characterized by IL-10 production, downregulation of membrane Fas and reduced upregulation of p21/Cip1 CDK-I message. These characteristics may prove important for the clinical use of ATRA and should be considered before starting ATRA therapy for myeloma.

Abstract
Like Bcl-2, peripheral benzodiazepine receptors (pBzRs) reside in mitochondrial pores, are frequently over-expressed in tumor cells, and can protect cells from apoptotic cell death. We now show that the high-affinity, pBzR-specific ligand, PK11195, chemosensitizes AML cells to relevant chemotherapeutics, but is relatively non-toxic as a single agent, and does not chemosensitize normal myeloid cells. PK11195 can block p-glycoprotein efflux in AMLs, contributing to increased daunomycin toxicity in efflux-competent AMLs, but can also sensitize AMLs to cytarabine and DNR-sensitize efflux-incompetent AMLs, presumably via mitochondrial pore effects documented in other models. Therefore, PK11195 might contribute to improved clinical outcomes in AML.

Abstract
Apoptosis of mature T cells may be an important pathophysiologic mechanism in diseases such as AIDS, cancer, and autoimmunity. In this study, in order to selectively protect T cells from dexamethasone (DEX)-induced apoptosis we constructed a fusion protein (anti-CD3sFv-IL-2) in which anti-CD3 single-chain Fv (sFv), the smallest unit of antibody recognizing the CD3 epsilon moiety of the T-cell receptor (TCR), was covalently linked to murine interleukin-2 (IL-2). Recombinant anti-CD3sFv protein was also expressed and used as a control. The purified anti-CD3sFv-IL-2 protein displayed IL-2 bioactivity in an IL-2 proliferation assay, which was inhibited by a neutralizing mIL-2 mAb. The anti-CD3sFv-IL-2 protein protected T lymphoma cells (S49.1) from DEX-induced apoptosis as demonstrated by oligonucleosomal genomic DNA fragmentation assay, and also recovered proliferation capacity of DEX-treated S49.1 cells and increased T cell composition both in DEX-treated spleen cell-populations and in DEX-treated mice, while the anti-CD3sFv protein did not. In addition, the anti-CD3sFv-IL-2 fusion protein was more efficient than a simple mixture of anti-CD3sFv and free rIL-2 in selectively protecting T cells from DEX-induced apoptosis. The levels of bcl-2 gene expression were significantly increased in DEX-treated T cells in the presence of the anti-CD3sFv-IL-2 protein. These studies indicate that the anti-CD3sFv-IL-2 fusion protein can selectively protect T cells from DEX-induced apoptosis and that the covalent linkage of anti-CD3sFv and IL-2 confines the anti-apoptotic effect of IL-2 to T cells.

Abstract
BACKGROUND We have previously demonstrated a decrease in intimal hyperplasia in vein bypass grafts from animals treated with all-trans-retinoic acid (atRA). The purpose of this study was to examine the effect of atRA on proliferation and apoptosis rates in healing vein bypass grafts. METHODS Interposition jugular vein bypass grafts were placed in the carotid artery of 30 New Zealand white rabbits. Animals received either atRA (10 mg/kg/d) or vehicle (corn oil) for a period of 2 weeks. Animals were killed at 3, 7, or 28 days after graft placement after having received 3 doses of 5-bromo-2'-¿Deoxyuridine (BRDU, 35 Mg/KG). Animals Were Perfusion Fixed, And Vein Grafts Were Prepared For Immunohistochemistry By Using Antibodies To Brdu, Proliferating Cell Nuclear Antigen, And Bcl-XL. Apoptosis Was Measured By Using The Tunel Assay. Histologic Sections Were Analyzed By A Pathologist Blinded To The Study, And An Index Of Positively Stained Cells Was Generated For Each Layer Of The Vein Graft Wall. RESULTS All-trans-retinoic acid reduced the proliferation index in the neointima of vein grafts during the first week after surgery. Apoptotic rates were higher in the intima of vein grafts from animals treated with atRA, which could not be explained by changes in bcl-xl expression. No differences were noted in the media or adventitia between the groups. CONCLUSIONS atRA decreased cell proliferation and increased apoptosis in the intima of healing vein bypass grafts. These effects contribute to decreased intimal hyperplasia, which has been previously noted.
