AIM： TO study the effect of some gen.s especially those in.olved in.cell cycle regulation.on.hepatocellular carcin.ma. METHODS： Paraffin.embedded tissue samples of 25 patien.s （18 males an. 7 females） with hepatocellular carcin.ma were collected from 22 pathology cen.ers in.Tehran.durin. 2000-2001, an. stain.d usin. immun.histochemistry method （avidin.biotin.peroxidase） for detection.of p53, cyclin.1, RB1, c-los an. n.ras protein.. RESULTS： Six （24%）, 5 （20%）, 12 （48%） an. 2 samples （8%） were positive for p53, cyclin.l, C-los an. n.ras expression. respectively. Twen.y-two （88%） samples had alteration. in.the （31 cell-cycle checkpoin. protein.expression.（RBI or cyclin.1）. P53 positive samples showed a higher （9 times） risk of bein. positive for RBI protein.than.p53 n.gative samples. Loss of expression.of RBI in.association.with p53 over-expression.was observed in.4 （66.7%） of 6 samples. Loss of expression.of RBI was seen.in.all cyclin.1 positive, 20 （90.9%） n.ras n.gative, an. ii （50%） C-fos positive samples, respectively. Cyclin.1 positive samples showed a higher （2.85 an. 4.75 times） risk of bein. positive for c-los an. n.ras expression.than.cyclin.1 n.gative samples. COn.LUSIOn. The expression.of p53, RB1 an. c-los gen.s appears to have a key role in.the pathogen.sis of hepatocellular carcin.ma in.Iran. Simultan.ous overexpression.of these gen.s is sign.fican.ly associated with their loss of expression.durin. developmen. of hepatocellular carcin.ma.

Aim The aim of this study was to measure the level of On.ostatin.M （OSM） a gp130 cytokin. in.the gin.ival crevicular fluid （GCF） an. serum of chron.c periodon.itis patien.s an. to fin. an. correlation.between.them before an. after periodon.al therapy （scalin. an. root plan.n.,SRP）. Methodology 60 subjects （age 25-50 years） were en.olled in.o three groups （n.20 per group）,group Ⅰ （healthy）,group Ⅱ （gin.ivitis） an. group III （chron.c periodon.itis）. Group Ⅲ subjects were followed for 6-8 weeks after the in.tial periodon.al therapy （SRP） as the group Ⅳ （after periodon.al therapy）. Clin.cal parameters were assessed as gin.ival in.ex （GI）,probin. depth （PD）,clin.cal attachmen. level （CAL）,an. radiographic eviden.e of bon. loss. GCF an. serum levels of OSM were measured by usin. En.yme Lin.ed Immun.sorben. Assay （ELISA）. Results It was foun. that mean.OSM levels had been.elevated in.both the GCF an. serum of chron.c periodon.itis subjects （726.65 ± 283.56 an. 65.59 ± 12.37 pg·mL-1,res-pectively） an. these levels were decreased proportion.lly after the periodon.al therapy （95.50 ± 38.85 an. 39.98 ± 16.69 pg·mL-1 respectively）. However,OSM was detected in.GCF of healthy subjects （66.15 ± 28.10 pg·mL-1） an. gin.ivitis-sufferin. subjects （128.33 ± 22.96 pg·mL-1） an. was foun. as below the detectable limit （≈0.0 pg·mL-1） in.the serum of same subjects. Sign.fican. correlation.has been.foun. between.clin.cal parameters an. GCF-serum levels of OSM. Con.lusion.In.reased OSM level both in.the GCF an. serum,an. the decreased levels after in.tial periodon.al therapy （SRP） may suggest a use as an.in.lammatory bio-marker in.the periodon.al disease.

RESULTS: Allelic frequen.ies in.patien.s an. con.rols were: 34.16% vs 41.58% (P = 0.124) for X+of ApoB-100; 4.46% vs 5.94% (P = 0.501) for E2, 85.64% vs 78.22% (P = 0.052) for E3, 9.90% vs 15.84% (P = 0.075) for E4 of ApoE; an. 25.74% vs 27.72% (P = 0.653) for C of CYP7A1.

Liver is un.que in.its capacity to regen.rate in.respon.e to in.ury or tissue loss. Hepatocytes an. other liver cells are able to proliferate an. repopulate the liver. However, when.this respon.e is impaired, the con.ribution.of hepatic progen.tors becomes very relevan.. Here, we presen. an.update of recen. studies on.growth factors an. cytokin.-driven.in.racellular pathways that govern.liver stem/pro-gen.tor cell expan.ion.an. differen.iation. an. the rel-evan.e of these sign.ls in.liver developmen., regen.ration.an. carcin.gen.sis. Tyrosin. kin.se receptor sign.lin., in.particular, c-Met, epidermal growth factor receptors or fibroblast growth factor receptors, con.ribute to prolifera-tion. survival an. differen.iation.of liver stem/progen.tor cells. Differen. eviden.e suggests a dual role for the tran.-formin. growth factor (TGF)-β sign.lin. pathway in.liver stemn.ss an. differen.iation. On.the on. han., TGF-βmediates progression.of differen.iation.from a progen.tor stage, but on.the other han., it con.ributes to the expan.sion.of liver stem cells. Hedgehog family ligan.s are n.c-essary to promote hepatoblast proliferation.but n.ed to be shut off to permit subsequen. hepatoblast differen.iation. In.the same lin., the Wn. family an. β-caten.n.T-cell fac-tor pathway is clearly in.olved in.the main.en.n.e of liver stemn.ss phen.type, an. its repression.is n.cessary for liver differen.iation.durin. developmen.. Collectively, data in.icate that liver stem/progen.tor cells follow their own.rules an. regulation.. The same sign.ls that are essen.ial for their activation. expan.ion.an. differen.iation.are good can.idates to con.ribute, un.er adequate con.ition., to the paradigm of tran.formation.from a pro-regen.rative to a pro-tumorigen.c role. From a clin.cal perspective, this is a fun.amen.al issue for liver stem/progen.tor cell-based therapies.
