The Prevalence of HIV Infection in Minority Indigenous Populations of the South-East Asia and Western Pacific Regions: A Systematic Review and Meta-analysis. AIDS Behav 2022; 27:2226-2242. [PMID: 36543946 PMCID: PMC9771782 DOI: 10.1007/s10461-022-03954-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 12/06/2022] [Indexed: 12/24/2022]
Abstract
A random effects meta-analysis was used to estimate the pooled prevalence of HIV infection within minority indigenous populations of the South-East Asia (SEAR) and Western Pacific Regions (WPR). Sub-group analyses were conducted, and the sources of heterogeneity explored through meta-regression. The majority of studies were undertaken in high HIV risk subpopulations. There was a paucity of data for many countries with data from China representing 70% of the comparative studies. Within minority indigenous populations the pooled prevalence of HIV infection was 13.7% (95% CI 8.9, 19) and 8.4% (95% CI 6.3, 10.7) among other populations. The prevalence differential between populations was significant in the WPR (adjusted odds ratio 1.1, 95% CI 1.0, 1.2). Across both regions, in contrast to other populations, minority indigenous did not experience any significant reduction in HIV prevalence over the years of data collection. There was large heterogeneity in the prevalence of HIV across studies.

Abstract
Background Epidemiological data on Treponema pallidum infection are scarce from the southwestern region of China. The purpose of this study was to determine the distribution and determinants of T. pallidum infection in the region. Methods A community-based cross-sectional study of 2608 participants aged ≥14 years was conducted in a rural area of southwestern China in 2014–15. A pretested questionnaire was used to collect sociodemographic characteristics and other factors associated with T. pallidum infection. The diagnoses of T. pallidum, human immunodeficiency virus (HIV), hepatitis B virus (HBV) and hepatitis C virus (HCV) infections were determined by commercial test kits. Logistic regression analysis was used to determine the correlates for T. pallidum infection, and adjusted odds ratios (aORs) and 95% confidence intervals (CIs) were calculated. Results The prevalence of T. pallidum infection was 1.2% (95% CI 0.8 to 1.7%). Risk factors varied by gender. In the male group, T. pallidum infection was significantly associated with ever injection drug use (aOR = 9.42, 95% CI 2.47 to 35.87) and HCV infection (aOR = 13.28, 95% CI 3.20 to 51.70). In the female group, correlates for T. pallidum infection included spouse having syphilis (aOR = 126.66, 95% CI 7.58 to 2122.94), ever having blood transfusion (aOR = 10.51, 95% CI 1.58 to 41.21) and HBV infection (aOR = 4.19, 95% CI 1.35 to 10.93). Conclusions The prevalence of T. pallidum infection was high in the rural area of southwestern China. Correlates for T. pallidum infection varied with sex specific. Intervention should be developed for the prevention and control of T. pallidum infection.

Abstract
We aimed to analyze factors related to human immunodeficiency virus (HIV) infection among 15 to 25-year-old rural unmarried Yi adolescents in Liangshan Yi Autonomous Prefecture from 2011 to 2016, and to investigate the relationship among the HIV-related risk factors.Three sites (Butuo, Zhaojue, and Ganluo counties) with a Yi population were selected from 2011 to 2016 in Liangshan prefecture. We used questionnaires to investigate demographic and behavioral characteristics and performed HIV testing. Logistic regression analysis and multiple correspondence analysis (MCA) were used to analyze the data.A total of 6311 qualified rural unmarried Yi adolescents were involved in this study, with an HIV infection rate of 4.18% (264/6311). Logistic regression analysis indicated that males (OR = 1.56, 95% CI = 1.17-2.08), illiteracy (OR = 2.70, 95% CI = 1.79-4.08), primary school education or below (OR = 1.62, 95% CI = 1.12-2.36), history of out-migrating for work (OR = 1.58, 95% CI = 1.18-2.13), and injecting drug user (IDU) (OR = 6.42, 95% CI = 3.06-13.46) contributed to the risk of HIV infection. MCA revealed a strong interrelationship between the following risk factors and HIV infection: aged 23 to 25 years, IDU, history of out-migrating for work, and ever having sexual behaviors.HIV infection among 15 to 25-year-old rural unmarried Yi adolescents in Liangshan is a serious issue. MCA and logistic regression analysis can be used to assess the relationship between risk factors for HIV infection.

Abstract
Xishuangbanna is a popular tourist destination in southern Yunnan Province, bordering with Vietnam and Laos, and Myanmar. There are more than 2 million cross-border travelers annually entering China at two land ports, Daluo and Mohan. To clarify the characteristics of HIV-1 prevalence among entry travelers, a retrospective epidemic investigation was conducted. Between 2003 and 2012, 196 among 91 432 entry travelers were detected to be HIV-1-positive, accounting for infection rate of 0.21%. Eighty-one gag-pol gene sequences were obtained for phylogenetic analyses and subsequent recombination analysis. It was shown that the most prevalent HIV-1 subtype in this population was circulating recombinant form (CRF) 01_AE (42, 51.86%), followed by CRF08_BC (17, 20.99%), CRF07_BC (4, 4.94%), B' (2, 2.47%), C (2, 2.47%), other recombinants (9, 11.11%), and undefined subtype (5, 6.17%). HIV-1 genotype distribution among travelers entering at two land ports is different, CRF01_AE and CRF08_BC accounted for a larger percentage among individuals from Daluo, whereas the proportions of subtype C and undefined URFs were larger among individuals from Mohan. The undefined subtype indicates the occurrence of novel HIV-1 subtype or CRF. This finding is useful for developing of AIDS prevention strategies.

Sustained high prevalence of viral hepatitis and sexually transmissible infections among female sex workers in China: a systematic review and meta-analysis. BMC Infect Dis 2016; 16:2. [PMID: 26732281 PMCID: PMC4702370 DOI: 10.1186/s12879-015-1322-0] [Citation(s) in RCA: 30] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2015] [Accepted: 12/12/2015] [Indexed: 02/06/2023] Open
Abstract
Background The 1980’s economic boom has been associated with a rapid expansion of China’s sex industry over the past three decades. Consequently, the spread of sexually transmitted infections (STIs) and hepatitis infections among female sex workers (FSW) has become an important public health issue in China. This study identifies prevalence and risks of hepatitis and STIs in Chinese FSWs. Method Four electronic databases were searched for Chinese and English language peer-reviewed studies conducted between 01/2000-12/2011 that reported prevalence of hepatitis and STIs (excluding HIV) among Chinese FSW. Following the PRISMA guidelines, meta-analysis was used to estimate pooled prevalence and 95 % confidence intervals for each infection. Result Three hundred and thirty nine articles (34 in English and 305 in Chinese) investigating 603,647 FSWs in 29 Chinese provinces were included in this review. Over the period 2000–2011, the seroprevalence of active hepatitis B and hepatitis C among FSW were 10.7 % (7.3–15.5 %) and 1.0 % (0.7–1.3 %), respectively. The most prevalent STI was human papillomavirus (HPV, 27.0 % [10.1–55.1 %]), followed by herpes simplex virus-2 (HSV-2, 15.8 % [11.7–20.9 %]), chlamydia (13.7 % [12.1–15.4 %]), gonorrhoea (6.1 % [5.3–7.0 %]), syphilis (5.2 % [4.8–5.7 %]), genital warts (3.3 % [2.5–4.2 %]) and Trichomonas vaginitis (2.1 % [1.5–24.2 %]). Disease burden of both hepatitis and STI among FSW were concentrated in South Central and Southwest China. In particular, chlamydia and syphilis demonstrated a significant declining trend during the studied period (P < 0.05). Compared with the general Chinese population, FSW had significantly higher prevalence of all STIs except Trichomonas vaginitis. Further, compared to the general FSW population, HIV-positive FSW had significantly higher prevalence of syphilis, chlamydia, HSV-2 and Trichomonas vaginitis. Conclusion Prevalence of hepatitis and STIs remained high and mostly stable among Chinese FSW over the period of 2000–2011. Targeted STI and hepatitis surveillance and interventions should be strengthened among Chinese FSWs, especially those who are HIV-positive.

Abstract
Background HIV prevalence is high in Liangshan, China (1.1 %). In 2012, people who inject drugs (PWID) in Xichang, the capital city, contributed to 60.0 % of the HIV infections. The goal of the current study was to examine the feasibility of implementing pharmacy-delivered harm reduction services (PDHRS) for PWID. Methods Face-to-face structured interviews with 403 PWID included questions on PWID’s experiences of syringe services and their specific experiences, acceptance, and potential usage of PDHRS. Results There were some reports of harassment/bad treatment from pharmacists (12.2 %) and police (17.6 %). Non-prescription syringe sales (NPSS) from pharmacies in single piece were the main source (82.1 %) of syringes. 72.5 % of PWID reported visiting 31.5 % of the identified pharmacies. Most (74.7 %) PWID disposed of their used syringes by throwing them away. Only one PWID brought used syringes back to a pharmacy in the past 30 days. Half of the PDHRS, such as printed materials about HIV, Hepatitis C and STIs; risk reduction services; (16.9 %) and sharps container to dispose of syringes (0.2 %) were offered by a few pharmacies (<20 % for each service). The acceptance rates among PWID toward currently offered services were high (≥91.1 %). All potential PDHRS were acceptable by most (68–95.3 %) PWID, and correspondingly 67–94.5 % of PWID reported they would use each service if offered. Conclusions NPSS from pharmacies provided many PWID in Liangshan with new syringes. However, disposal of used syringes was problematic. At the time of investigation, half of 16 assessed PDHRS were already available in pharmacies in Xichang. PWID were ready to use all the potential PDHRS and14 of 16 PDHRS were feasible to provide. HIV testing kits may be available in pharmacies in the future. Many pharmacy-delivered harm reduction services are feasible and acceptable among PWID in Xichang, China.

Reality and feasibility for pharmacy-delivered services for people who inject drugs in Xichang, China: Comparisons between pharmacy staff and people who inject drugs. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2015; 27:113-20. [PMID: 26123897 DOI: 10.1016/j.drugpo.2015.05.015] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2014] [Revised: 03/06/2015] [Accepted: 05/28/2015] [Indexed: 11/16/2022]
Abstract
BACKGROUND In 2010, the reported overall HIV prevalence in Liangshan China (1.14%) was 19.7 times of the overall estimated prevalence in China (0.058%), and injection drug use contributed to 60.0% of overall HIV infections in Xichang, the Capital city of Liangshan. With one national methadone clinic and three outpatient service sites, and three NEP sites, the HIV prevalence among people who inject drugs (PWID) in Xichang was estimated as 18.0% (2.8 times of national HIV prevalence among PWID) in 2012. METHODS Face-to-face questionnaire interviews were used in a cross-sectional study to assess experience, attitudes, possibility and acceptability of implementing 8 pharmacy-delivered services among PWID (n=403). The concordance of attitudes, possibility and acceptability between PWID and pharmacy staff (n=50) was examined. RESULTS Rather than medical facility (23.1%), and NEP (8.9%), pharmacies were the main source of syringes for PWID in the last 12 months (82.1%), PWID (63.5%) reported syringes could be bought in single piece and at the price of $0.16 USD (59.3%). In the last 30 days, only 1 PWID brought used syringes back to a pharmacy. Pharmacy staff's attitudes were generally negative but nearly neutral (average score -0.18), discrimination/business concerns against pharmacy-delivered services existed, and 4 of 5 compared attitude questions between PWID and pharmacy staff were statistically different (p<0.01). 5 of 8 pharmacy-delivered services were available for PWID at low level (≤16.9%). Pharmacy staff's supportive perception for pharmacy-delivered services focused on pharmacies' initiate roles targeting on general population more than on PWID. PWID were more supportive and optimistic than pharmacy staff toward potential usage of pharmacy-delivered services (p<0.05). CONCLUSION Pharmacy-delivered services for PWID in Xichang were partly in reality, and could be feasible. It is urgently needed to address the legal requirements and remuneration for pharmacies. Pharmacy staff should receive additional training on services related knowledge and skills, cultural sensitivity toward PWID. Successful pharmacy-delivered services would benefit from identifying mutual interest and benefit between pharmacies and PWID.

Abstract
Limited information is available on the prevalence of hepatitis C virus (HCV) in the general population in China. A community-based epidemiological study was conducted in three counties in eastern China. A total of 149 175 individuals were investigated in 60 communities in three counties in Jiangsu province, eastern China, of whom 1175 subjects [0·79%, 95% confidence interval (CI) 0·74-0·83] were HCV antibody positive. The prevalence was low in children (0·09%, 95% CI 0·04-0·17), but increased progressively from adolescents (0·20%, 95% CI 0·15-0·28) to adults aged ⩾21 years (95% CI 0·15-1·64). Women had a higher prevalence of HCV infection than men in most age groups. In a multilevel regression analysis, age, sex, education, occupation, blood transfusion [odds ratio (OR) 2·91, 95% CI 1·09-5·37], invasive testing (OR 1·28, 95% CI 1·14-1·61), and dental therapy (OR 2·27, 95% CI 1·41-3·42) were associated with HCV infection. In conclusion, although the prevalence of HCV in this population was lower than reported from national levels, the total reservoir of infection is significant and warrants public health measures, such as health education to limit the magnitude of the problem.

A randomized controlled trial evaluating the efficacy of a theory-based intervention promoting condom use among Chinese monogamous female sexually transmitted infection patients. Int J Behav Med 2014; 21:719-29.

Abstract
BACKGROUND Chinese monogamous women may contract sexually transmitted diseases (STD) from their sole male sex partner, but these women do not have high self-efficacy in negotiating about condom use with their regular sex partners. PURPOSE We aim to investigate the relative efficacy of a theory-based and clinic-based cognitive behavioral intervention versus a control intervention in increasing prevalence of condom use with their male sex partner among Chinese monogamous female sexually transmitted disease patients. METHODS A randomized controlled trial (RCT) was conducted. Participants were randomly allocated into the intervention group (n = 88) or the control group (n = 88). All participants were phone interviewed at baseline and at 2 and 3 months after completion of the baseline survey. The three-session group intervention was based on the information-motivation-behavioral skills (IMB) model. Participants of the control group were provided with educational pamphlets. The primary outcome was consistent condom use in the last month. Relative risks were calculated, and multiple logistic regression models were fit. RESULTS As compared to the control group, the intervention group reported higher prevalence of consistent condom use with the sole male sex partner in the last month at month 2 (75.3 versus 59.8%, RR = 1.26, 95% CI = 1.01, 1.57) and month 3 (77.8 versus 54.6%, RR = 1.42, 95% CI = 1.13, 1.80), whilst the baseline between-group difference was statistically non-significant. Some other secondary outcomes such as "intention to request condom use in the next month even if the sexual partner dislikes using condoms" were also statistically significant. Furthermore, the majority (94%) of the intervention group members were satisfied with the intervention. CONCLUSIONS The theory-based intervention is potentially efficacious, but the follow-up period was relatively short. Large-scale randomized clinical trials and subsequent translational research are greatly warranted in the future.

Abstract
The treatment of chronic hepatitis C virus (HCV) infection has the potential to change significantly over the next few years as therapeutic regimens are rapidly evolving. However, the burden of chronic infection has not been quantified at the global level using the most recent data. Updated estimates of HCV prevalence, viremia and genotypes are critical for developing strategies to manage or eliminate HCV infection. To achieve this, a comprehensive literature search was conducted for anti-HCV prevalence, viraemic prevalence and genotypes for all countries. Studies were included based on how well they could be extrapolated to the general population, sample size and the age of the study. Available country estimates were used to develop regional and global estimates. Eighty-seven countries reported anti-HCV prevalence, while HCV viraemic rates were available for fifty-four countries. Total global viraemic HCV infections were estimated at 80 (64-103) million infections. Genotype distribution was available for ninety-eight countries. Globally, genotype 1 (G1) was the most common (46%), followed by G3 (22%), G2 (13%), and G4 (13%). In conclusion, the total number of HCV infections reported here are lower than previous estimates. The exclusion of data from earlier studies conducted at the peak of the HCV epidemic, along with adjustments for reduced prevalence among children, are likely contributors. The results highlight the need for more robust surveillance studies to quantify the HCV disease burden more accurately.

Abstract
Background While many human immunodeficiency virus (HIV) studies have been performed in Liangshan, most were focused only on HIV infection and based on a sampling survey. In order to fully understand HIV and hepatitis C virus (HCV) prevalence and related risk factors in this region, this study implemented in 2009, included a survey, physical examination, HIV and HCV test in two towns. Methods All residents in two towns of the Butuo county were provided a physical examination and blood tests for HIV and HCV, and then followed by an interview for questionnaire. Results In total, 10,104 residents (92.4%) were enrolled and 9,179 blood samples were collected for HIV and HCV testing, 6,072 were from individuals >14 years old. The rates of HIV, HCV, and HIV/HCV co-infection were 11.4%, 14.0%, and 7.7%, respectively for >14-year-old residents. The 25–34 yr age group had the highest prevalence of HIV, HCV, and HIV/HCV co-infections, reaching 24.4%, 26.2% and 16.0%, respectively. Overall, males had a much higher prevalence of all infections than females (HIV: 16.3% vs. 6.8%, HCV: 24.6% vs. 3.9%, HIV/HCV co-infected: 14.7% vs. 1.1%, respectively; P = 0.000). Approximately half of intravenous drug users tested positive for HIV (48.7%) and 68.4% tested positive for HCV. Logistic regression analysis showed that five factors were significantly associated with HIV and HCV infection: gender (odds ratio [OR] = 5.8), education (OR = 2.29); occupation (student as reference; farmer: OR = 5.02, migrant worker: OR = 6.12); drug abuse (OR = 18.0); and multiple sexual partners (OR = 2.92). Knowledge of HIV was not associated with infection. Conclusion HIV and HCV prevalence in the Liangshan region is very serious and drug use, multiple sexual partners, and low education levels were the three main risk factors. The government should focus on improving education and personal health awareness while enhancing drug control programs.

Abstract
BACKGROUND The human immunodeficiency virus (HIV) and hepatitis C virus (HCV) are major public health problems. Many studies have been performed to investigate the association between demographic and behavioral factors and HIV or HCV infection. However, some of the results of these studies have been in conflict. METHODOLOGY/PRINCIPAL FINDINGS The data of all entrants in the 11 national methadone clinics in the Yi Autonomous Prefecture from March 2004 to December 2012 were collected from the national database. Several spatial regression models were used to analyze specific community characteristics associated with the prevalence of HIV and HCV infection at the township level. The study enrolled 6,417 adult patients. The prevalence of HIV infection, HCV infection and co-infection was 25.4%, 30.9%, and 11.0%, respectively. Prevalence exhibited stark geographical variations in the area studied. The four regression models showed Yi ethnicity to be associated with both the prevalence of HIV and of HIV/HCV co-infection. The male drug users in some northwestern counties had greater odds of being infected with HIV than female drug users, but the opposite was observed in some eastern counties. The 'being in drug rehabilitation variable was found to be positively associated with prevalence of HCV infection in some southern townships, however, it was found to be negatively associated with it in some northern townships. CONCLUSIONS/SIGNIFICANCE The spatial modeling creates better representations of data such that public health interventions must focus on areas with high frequency of HIV/HCV to prevent further transmission of both HIV and HCV.

The geographic distribution patterns of HIV-, HCV- and co-infections among drug users in a national methadone maintenance treatment program in Southwest China. BMC Infect Dis 2014; 14:134. [PMID: 24612875 PMCID: PMC3975583 DOI: 10.1186/1471-2334-14-134] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2013] [Accepted: 03/04/2014] [Indexed: 11/26/2022] Open
Abstract
Background HIV-, HCV- and HIV/HCV co-infections among drug users have become a rapidly emerging global public health problem. In order to constrain the dual epidemics of HIV/AIDS and drug use, China has adopted a methadone maintenance treatment program (MMTP) since 2004. Studies of the geographic heterogeneity of HIV and HCV infections at a local scale are sparse, which has critical implications for future MMTP implementation and health policies covering both HIV and HCV prevention among drug users in China. This study aimed to characterize geographic patterns of HIV and HCV prevalence at the township level among drug users in a Yi Autonomous Prefecture, Southwest of China. Methods Data on demographic and clinical characteristics of all clients in the 11 MMTP clinics of the Yi Autonomous Prefecture from March 2004 to December 2012 were collected. A GIS-based geographic analysis involving geographic autocorrelation analysis and geographic scan statistics were employed to identify the geographic distribution pattern of HIV-, HCV- and co-infections among drug users. Results A total of 6690 MMTP clients was analyzed. The prevalence of HIV-, HCV- and co-infections were 25.2%, 30.8%, and 10.9% respectively. There were significant global and local geographic autocorrelations for HIV-, HCV-, and co-infection. The Moran’s I was 0.3015, 0.3449, and 0.3155, respectively (P < 0.0001). Both the geographic autocorrelation analysis and the geographic scan statistical analysis showed that HIV-, HCV-, and co-infections in the prefecture exhibited significant geographic clustering at the township level. The geographic distribution pattern of each infection group was different. Conclusion HIV-, HCV-, and co-infections among drug users in the Yi Autonomous Prefecture all exhibited substantial geographic heterogeneity at the township level. The geographic distribution patterns of the three groups were different. These findings imply that it may be necessary to inform or invent site-specific intervention strategies to better devote currently limited resource to combat these two viruses.

Abstract
Background Sexually transmitted infections (STIs), including Hepatitis B and C virus, are emerging public health risks in China, especially among men who have sex with men (MSM). This study aims to assess the magnitude and risks of STIs among Chinese MSM. Methods Chinese and English peer-reviewed articles were searched in five electronic databases from January 2000 to February 2013. Pooled prevalence estimates for each STI infection were calculated using meta-analysis. Infection risks of STIs in MSM, HIV-positive MSM and male sex workers (MSW) were obtained. This review followed the PRISMA guidelines and was registered in PROSPERO. Results Eighty-eight articles (11 in English and 77 in Chinese) investigating 35,203 MSM in 28 provinces were included in this review. The prevalence levels of STIs among MSM were 6.3% (95% CI: 3.5–11.0%) for chlamydia, 1.5% (0.7–2.9%) for genital wart, 1.9% (1.3–2.7%) for gonorrhoea, 8.9% (7.8–10.2%) for hepatitis B (HBV), 1.2% (1.0–1.6%) for hepatitis C (HCV), 66.3% (57.4–74.1%) for human papillomavirus (HPV), 10.6% (6.2–17.6%) for herpes simplex virus (HSV-2) and 4.3% (3.2–5.8%) for Ureaplasma urealyticum. HIV-positive MSM have consistently higher odds of all these infections than the broader MSM population. As a subgroup of MSM, MSW were 2.5 (1.4–4.7), 5.7 (2.7–12.3), and 2.2 (1.4–3.7) times more likely to be infected with chlamydia, gonorrhoea and HCV than the broader MSM population, respectively. Conclusion Prevalence levels of STIs among MSW were significantly higher than the broader MSM population. Co-infection of HIV and STIs were prevalent among Chinese MSM. Integration of HIV and STIs healthcare and surveillance systems is essential in providing effective HIV/STIs preventive measures and treatments. Trial Registration PROSPERO No: CRD42013003721

Abstract
Piperlongumine (PL), isolated from the fruit of Long pepper, Piper longum, is a cancer-inhibiting compound that selectively kills tumor cells while sparing their normal counterparts. Here we evaluated the efficacy with which PL suppresses malignant B cells derived from a newly developed, double-transgenic mouse model of human endemic Burkitt lymphoma (BL), designated mCD40-LMP1/iMyc(Eμ). PL inhibited tumor cell proliferation in a concentration-dependent manner and induced apoptosis of neoplastic but not normal B cells. Treatment with PL resulted in downregulation of EBV-encoded LMP1, cellular Myc, constitutive NF-κB activity, and a host of LMP1-Myc-NF-κB-regulated target genes including Aurka, Bcat1, Bub1b, Ccnb1, Chek1, Fancd2, Tfrc and Xrcc6. Of note, p21(Cip1)-encoding Cdkn1a was suppressed independent of changes in Trp53 mRNA levels and p53 DNA-binding activity. Considering the central role of the LMP1-NF-κB-Myc axis in B-lineage neoplasia, these findings further our understanding of the mechanisms by which PL inhibits B-lymphoma and provide a preclinical rationale for the inclusion of PL in new interventions in blood cancers.
