The Pacific lineage (2E) of JC polyomavirus is prevalent in Sumba Island, Eastern Indonesia
Recent studies have identified a Pacific lineage (2E) of JC polyomavirus (also designated as JC virus or JCV) that occurs in both Island Southeast Asia and Oceania, but not in mainland Asia. It has been postulated that this lineage traveled with Austronesian-speaking people who are now spread throughout Island Southeast Asia and Oceania (excluding Australia and inland and southern New Guinea). However, to date, the 2E lineage has been identified …
Human dispersals based on a global phylogenetic analysis of JC virus isolates of genotype B1-b
JC virus (JCV) is a useful marker for tracing human dispersal. Four genotypes of JCV (CY, SC, B1-b, and MY) are mainly distributed in Asia. The population history of humans carrying CY, SC, or MY has been studied in some detail, but that of humans carrying B1-b remains poorly understood. The objective of this study was to gain insights into the population history of Asians carrying B1-b. A neighbor-joining phylogenetic tree was reconstructed from…
JC polyomavirus lineages common among Kiribati Islanders
Although JC polyomavirus (JCPyV) genotyping is a promising method in clarifying the peopling of the Pacific, the distribution of JCPyV lineages has been elucidated only in a few Pacific populations. To clarify JCPyV lineages of the Kiribati Islanders, we collected urine samples from 48 Kiribati fishermen (mainly from the Gilbert Islands), who called in at a Japanese port for unloading. From the urine samples, we amplified the 610-bp IG region (VT…
Dispersal of southeastern Asians based on a global phylogenetic analysis of JC polyomavirus isolates of genotype SC
The SC genotype of the JC polyomavirus is the key to understanding the origin and dispersal of southeastern Asians. We performed a phylogenetic analysis based on complete DNA sequences of 24 SC isolates worldwide, including 11 in China, three in Vietnam, two in Malaysia, two in Myanmar, one in Indonesia, two in Mauritius, one in Zambia, one in South Africa, and one in Hawaii, USA. The results suggest that although SC isolates worldwide can be cla…
Phylogenetic analysis of major African genotype (Af2) of JC virus
Both mtDNA and the Y chromosome have been used to investigate how modern humans dispersed within and out of Africa. This issue can also be studied using the JC virus (JCV) genotype, a novel marker with which to trace human migrations. Africa is mainly occupied by two genotypes of JCV, designated Af1 and Af2. Af1 is localized to central/western Africa, while Af2 is spread throughout Africa and in neighboring areas of Asia and Europe. It was recent…
Genetic diversity of JC virus in the Saami and the Finns
The JC virus (JCV) genotyping method was used to gain insights into the population history of the Saami and the Finns, both speaking Finno‐Ugric languages and living in close geographic proximity. Urine samples from Saami and Finns, collected in northern and southern Finland, respectively, were used to amplify a 610‐bp JCV‐DNA region containing abundant type‐specific mutations. Based on restriction site polymorphisms in the amplified fragments, w…
Two distinct genotypes (MY-x and MX) of JC virus previously identified in Hokkaido Ainu
Genotyping the urinary JC virus (JCV) DNA is a useful means to gain new insights into the origin of ethnic groups. We recently detected thirteen JCV isolates from the Ainu, an indigenous population living on Japan’s northernmost island (Hokkaido). Based on phylogenetic analysis, these isolates were classified into five genotypes: two (MX and MY-x) were first identified in the Ainu, two (EU-a/Arc and EU-c) are prevalent in northeastern Siberians a…
JC virus genotyping suggests a close contact or affinity between Greenland Inuit and other circumarctic populations
We used the JC virus genotyping method to investigate the origins of Greenland Inuits. Using polymerase chain reaction, we detected six JC virus isolates in urine samples collected from Inuits in northwestern and southeastern Greenland. Phylogenetic analysis of the complete and partial DNA sequences of these isolates demonstrated that all isolates belonged to the EU-a1/Arc cluster previously identified in native northeastern Siberians (e.g. Chukc…
Genotypes of JC virus in Southeast Asia and the western Pacific
JC virus (JCV) genotyping is a novel method of tracing human migrations. In the present study, we used this method to gain insights into human expansions to the western Pacific. Using the whole genome approach, four genotypes of JCV (8A, 8B, 2E, and 7A) were previously detected in the island populations of the western Pacific. Using the same approach, we detected five genotypes (B1-a, B3-a, B3-b, SC-f, and SC-x) in Filipino populations (B3-b and …
JC virus genotype profile in the Mamanwa, a Philippine Negrito tribe, and implications for its population history
JC virus (JCV) is ubiquitous in the human population, usually being transmitted from parents to children during cohabitation. JCV genotyping is a useful means of elucidating the origins of various ethnic groups in the world. We used this method to gain insights into the origin of the Mamanwa, a Philippine Negrito tribe in Northeast Mindanao. We found that the Mamanwa carried two major JCV genotypes, B3-b/2E and SC-f/7A. This was in contrast with …
Genetic diversity of JC virus in the modern Filipino population
The Philippines is generally believed to have been established by various peoples who migrated from neighboring areas. To gain new insights into the peopling of the Philippines, we used the JC virus (JCV) genotyping approach. We collected about 50 urine samples on each of two representative islands of the Philippines, Luzon and Cebu. DNA was extracted from the urine samples and used to amplify the 610‐bp region (IG region) of the viral genome. Fo…
Phylogenetic Analysis of JC Virus DNAs Detected in Ainus
JC ウイルス (JCV) DNA の系統解析によりアイヌの起源を解明することを目的として, 北海道の3地域(浦河, 白老, 旭川)に住むアイヌ30名から尿を採取した。尿から検出された JCV DNA (n = 13) は5つのゲノム型 (MY-b, MY-x, MX, EU-a/Arc, EU-c) に分類された。MY-b, EU-a/Arc, EU-cは過去に近隣の人類集団から検出されたが, MY-xとMXは今回初めてアイヌから検出された。得られた知見から, (1) 東北アジアから渡来した複数の人類集団が現代アイヌを築いたこと, (2) ヨーロッパ人に近縁の東北シベリア先住民の祖先集団が現代アイヌの中核を形成したこと, (3) 縄文人を形成した集団や新規な東北アジア系集団も現代アイヌの形成に寄与したことが示唆された
Peopling of Myanmar as Demonstrated by Genotyping of Urinary JC Virus DNA
The genotyping of urinary JC virus (JCV) DNAs is a novel means of elucidating the origin of ethnic populations. We adopted this method to gain insights into the peopling of Myanmar. JCV genotype profiles at two sites of Myanmar, Yangon facing the Andaman Sea and Peinnebeen located in the central part of Myanmar, were reported previously. In this study, we elucidated JCV genotype profiles at three other sites of Myanmar: Chaungtha Beach facing the…
JC Virus Genotypes in Northwestern China
Genotyping of urinary JC virus (JCV) DNAs is a useful means of elucidating the origin of ethnic populations. We previously reported JCV genotypes in eastern China and Mongolia. To gain a comprehensive picture of JCV genotypes in China, we collected urine samples at three northwestern sites along the Silk Road: X'ian, Lanzhou and Urumqi. DNA was extracted from urine samples, and used to amplify the 610-base-pair region (IG region) of the viral gen…
Peopling of Japan as Revealed by Genotyping of Urinary JC Virus DNA
It has been shown that the typing of urinary JC polyomavirus (JCV) DNA offers a novel means of tracing human migrations. We used this approach to elucidate the colonization of the Japanese Archipelago. Approximately 1, 000 JCV DNA-positive urine samples were collected throughout the Japanese Archipelago, and used to amplify a 610-base-pair JCV DNA region (IG region). We determined about 100 IG sequences, from which a phylogenetic tree was constru…
