WELLINGTON, May 24 (Xinhua) -- New Zealand researchers have found a way to stop the growth of certain cancer tumors by " silencing" a group of PAX genes, members of a small family of genes that play important roles in embryonic development, but also allow cancer cells to grow and divide in adult tissue.In an article published in UK medical journal Oncogene, Otago University Professor Michael Eccles and colleagues revealed how they used the PAX8 gene to kill cancer cells.After detecting high levels of PAX8 protein in the majority of kidney, ovarian and thyroid cancers they studied, the researchers used molecular techniques to silence the PAX8 gene in several cancer cell lines."We found that these PAX8-depleted cancer cells ceased growing and dividing. The cells were essentially stopped in their tracks through the failure of multiple mechanisms and pathways crucial to their cell division cycle. They then entered into a state called senescence in which they no longer divided, and after that they ultimately died," Eccles said in a statement from the university Tuesday.The findings suggested that PAX8 could be a good target for the development of new cancer therapies, he said."Any resulting drugs would be a long way down the road, but in the meantime this research helps confirm that a focus on PAX genes may prove to be a fruitful line of attack against a number of cancers," he said.The research was supported by grants from the Health Research Council of New Zealand. It formed the main piece of work carried out by Otago doctoral graduate Caiyun (Grace) Li, now a postdoctoral fellow at Stanford University. Study co-authors also included Professor Antony Braithwaite and master's student Jen Nyman.In 2003, research led by Eccles discovered that proteins from one or more of the nine PAX genes were present in many common cancers. They found that "silencing" the gene expression of PAX2 in ovarian and bladder cancer cells, and of PAX3 in melanoma, led to the rapid death of the cells.

CHANGSHA, Jan. 25 (Xinhua) -- More than 8,000 fake goods were destroyed Tuesday in central China's Hunan Province, as part of Chinese efforts to protect intellectual property rights (IPR).Supervised by Changsha customs official, trucks rolled over a huge pile of counterfeit electronic devices in the city, the provincial capital.The trucks crashed imitation Nokia, Motorola and Apple laptop computers, cell phones, earphones and compact discs.Pirated books and Gucci handbags were incinerated.Changsha customs have confiscated more than 34,000 fake items worth 1.3 million yuan (197,470 U.S. dollars) over the past two years, said Liu Zili, a customs official.Some confiscated fake goods were donated to Red Cross societies and quake-devastated regions, in accordance with China's IPR protection regulations.

BEIJING, Feb. 1 (Xinhua) -- A ceremony with a bonfire and firecrackers was held Tuesday night in the new seat of a quake-leveled county in southwest China's Sichuan Province, prior to the Chinese Lunar New Year on Thursday.The Lunar New Year, or Spring Festival, is the most important Chinese holiday. It is a time for family reunions, gift giving and fireworks.It will be even merrier for the survivors of the Wenchuan earthquake in 2008, who just moved into their new homes in the new town.The earthquake survivors are preparing for the first Spring Festival in their new homes.Xia Tianfeng of Beichuan County, Mianyang City, is sticking red paper decorations onto the windows of her new house for good luck in the New Year."We finally have our new house. Why wouldn't I be happy?" asked Xia.She and her family lived in a makeshift house for two years before moving into their new house one month ago.Dong Depa, 43, and his family moved into their new house in Yingxiu Town, the epicenter of the quake, five days ago."I can pay off the debt incurred to build the house in two years," said Dong, who spent only 30,000 yuan (4,541 U.S. dollars) for the house's construction and decoration, with the rest being shouldered by the government.Dong lost his two children in the quake but he and his wife have since had another child, a son."Last year, we spent the Spring Festival in the dormitory of the brick factory where I work as a cook. Now we can finally enjoy the festival in our own home," said Dong, unable to conceal his joy.Xia told Xinhua the ceremony for the new county seat was the real taste for a happy new year.Reconstruction has finished in the quake-hit zones in Sichuan, with most survivors now in their new houses.In Beichuan County alone, 96.5 percent of the survivors already have their new house.The new county seat is located in Yongchang Town, about 23 kilometers from the quake-leveled old one.The 8.0-magnitude earthquake struck southwest China on May 12, 2008, leaving about 80,000 people dead or missing.Waving goodbye to their temporary barracks, 7,397 households have been allocated new apartments, among which 3,504 households were former Beichuan residents, while others were from different Wenchuan earthquake-hits regions."The new apartment has already been simply decorated by the time I received the door key. With our new furniture, we can wait no longer to move into the home," said 45-year-old Xie Xinghe, a former resident of Beichuan.Including 50,000 yuan (about 7,575 U.S. dollars) in loans, Xie paid a preferential price of 79,600 yuan (about 12,000 U.S dollars) for the 100 square meter new apartment.Losing his only son in the earthquake, Xie and his wife adopted a one-year-old boy."It is the child who brings me new hope for the future," Xie said. Following the Lunar New Year celebration in his new home, Xie will try his best to work for some years to pay back the loan and save money to ensure a better education for his son."It is such magic to build a new town within three years, even so anywhere around the world. And we see it now," said Xu Zhenxi, director with the headquarter of new town program of Beichuan, which is supported by east China's Shandong Province.From May 25, 2009 to September 25, 2010, Shandong Province supported the new Beichuan county seat project, which was completed within 15 months.

CHANGCHUN, Jan. 22 (Xinhua) -- Chinese Vice President Xi Jinping stressed political integrity as the most important criteria in electing Communist Party cadres, during his three-day inspection tour in northeast Jilin province, which ended Saturday.The standards of political integrity and professional competence, with the former being the most important, should be strictly observed in the upcoming election of the new term for Party Committee members at provincial, city, county and township levels, Xi, a Standing Committee member of the Communist Party of China (CPC) Central Committee Political Bureau, said.During his meeting with leaders of the provincial Party Committee and provincial government of Jilin, Xi said efforts should be made to reinforce the notion of putting people first and exercising the state power for the people among carders.Chinese Vice President Xi Jinping (2nd L front) talks with a staff member at a workshop of FAW car factory in Changchun, capital of northeast China's Jilin Province, Jan. 21, 2011. Xi made an inspection tour in Jilin from Jan. 20 to 22.While visiting a community Party organization, Xi also asked grass-roots Party organizations to give priority to building a closer bond with the public and serving the public.During his visit to several companies, including Changchun-based First Automobile Works, Xi called for efforts to develop technology-intensive industries and the manufacturing of high-end products to promote economic restructuring.He also visited flood-hit areas to observe the relocation of flood victims and reconstruction work. Jilin Province was hit by unprecedented floods last July and August.He asked local governments to rebuild flood-damaged homes as soon as possible and repair those destroyed water conservancy projects and encourage farmers to grow crops on flooded lands.

LOS ANGELES, March 5 (Xinhua) -- Law enforcement agencies are now using smart phones to track and arrest graffiti vandals in Los Angeles, a newspaper report said on Saturday.The graffiti-tracking program, spearheaded by the Tracking and Automated Graffiti Removal System, or TAGRS, allows graffiti- cleaning crews equipped with smart phones to photograph the markings and upload them to a Los Angeles Police Department (LAPD) database, the Los Angeles Times said.The photos are used to gather evidence for prosecution and restitution, the paper quoted city officials as saying.Once the graffiti suspects' identities are discovered, the information is added to the TAGRS database and may eventually uncover incidents involving the same suspects, the paper said.The LAPD launched a pilot project in 2009 in Van Nuys near Los Angeles, modeling its version on one run by the Orange County Sheriff's Department, according to the report.The program is now anchored at four LAPD stations, Van Nuys, Hollenbeck, Central and Harbor, said Mayor Antonio Villaraigosa's spokeswoman Casey Hernandez.Los Angeles spends about 10 million dollars a year cleaning up graffiti, Hernandez said.
