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.

BEIJING, March 4 (Xinhuanet) -- Well-educated and well-paid single Chinese women were at the forefront of a boom in travel by the country's women in 2010.According to the 2010 Trend Report of Women's Travel, the amount of travel by Chinese women increased by 20 percent last year, with well-educated and well-paid single women becoming the main force in the tourism market.Travel expenditure per capita by women on the Chinese mainland was 4,300 yuan (5) in 2010, and the 20-percent year-on-year rise was much larger than the 9- percent increase for men.Qunar.com, the world's largest online travel search engine in Chinese, released the report. The Beijing-based site was launched in 2005. According to Dai Zheng, vice-president of Qunar.com, women's growing spending power has led to more of them choosing travel as a way to cosset themselves, especially well-educated and well-paid single women, who travel for relaxation and self-improvement.Zhang Jing, 31, who works for a consulting company in Shanghai and earns nearly 20,000 yuan monthly, spent 15,000 yuan on travel last year, including a trip to the Tibet autonomous region in Southwest China and another to Singapore."Travel not only releases work pressure, but also opens up my horizon on the world. I like to see and experience how others live," said Zhang, who plans to visit Thailand in May with two female friends who are both around 30 years of age."Women are active in all of our travel projects. I definitely feel that it's mostly women who are interested in our products," said Zhao Huijin, who works in the booking center of the E-commerce department of China International Travel Service (CITS).Zhao's remarks to China Daily were echoed by the report, which said more than 65 percent of decisions about travel products and travel expenditure were made by women.In addition, women tended to be more demanding of hotels, and preferred to comment and find fault with hotels. On the forum at Qunar.com, women made nearly 70 percent of the comments on hotels.Women's more active participation in travel means that when the industry's decision-makers develop new travel products they take greater note of women's views about travel.In recent years, products targeted at women have appeared, such as women's hotels, certain hotel floors especially reserved for women, and travel themed around shopping, healthcare and relaxation.Le Meridien, a five-star hotel in Xiamen, Fujian province, set up a floor tailored for women customers in July 2010.Adding to the high quality of certain facilities that women care about most, such as excellent sound insulation, the 32 suites on this floor are also equipped with products especially for women, including fresh fruits, low-calorie food, yoga mats, bath salts, facial masks and hangers for silk clothes."These rooms are warmly appreciated by ladies, and we hope to meet women customers' needs both physically and psychologically through appropriate care," said Wang Yan, assistant manager of the hotel's marketing and communication department.The report also revealed that women's choice of destination is strongly influenced by fashion. They enjoy traveling to scenic spots featured in the latest romantic movies and TV dramas.

BEIJING, March 8 (Xinhuanet) -- U.S. Food and Drug Administration (FDA) announced there was no new reason for safety concern in Pfizer Inc's Prevenar and Sanofi Aventis SA's ActHIBor vaccines, according to media reports Tuesday.Health agencies "have not detected new safety concerns or unusual reporting patterns" in the vaccines, which are used to prevent forms of meningitis and pneumonia, FDA spokeswoman Shelly Burgess said in an emailed statement.Health agencies in the United States will continue to monitor the vaccines for safety, the spokeswoman added.The Japanese health ministry had decided to suspend the vaccines after four unexplained deaths were reported. The causes of the deaths are still investigated, the Japanese ministry said in a release on its website.

CANBERRA, April 14 (Xinhua) -- Scientists on Thursday expressed disappointment to the decision to cancel the long-running Australian Science Festival in Canberra.The festival has been operating during August for the past 19 years with free and ticketed science education activities.However, the festival organizers on Wednesday announced to halt this year's program after failing to secure support from the Australian Capital Territory state government in time to arrange events.According to Australian Science Communicators president, Jesse Shore, thousands of school children have attended the festival over its history to learn more about science as a career."It's encouraged other activities to join it, it was very important in getting National Science Week started, and that's stimulated a lot of other science communication activities," he told ABC News on Thursday.Shore said the decision to close it down is unfortunate as the event has been very influential and instrumental promoting science communications activities.He said he hopes that a number of people would gather together in a new partnership, with new ideas and hopefully a new funding base.

XICHANG, Sichuan, April 10 (Xinhua) -- China early Sunday morning successfully launched its eighth orbiter which will form part of its indigenous satellite-navigation and -positioning network.A Long March-3A carrier rocket carrying the "Beidou," or Compass, navigation satellite took off at 4:47 a.m. Sunday from the Xichang Satellite Launch Center in southwest China's Sichuan Province.It will join seven other satellites already in orbit to form a network which will eventually consist of more than 30 satellites.The launching of the satellite marks the establishment of a basic system for the navigation and positioning network, said an unidentified spokesperson for the Xichang Satellite Launch Center.China will launch more satellites within the coming two years to finish a regional network to provide navigation services with high precision and credibility for industries and sectors such as mapping, fishery, transportation, meteorology and telecommunication, in the Asia-Pacific regions, the spokesperson said.The network is scheduled to be able to provide global services by 2020.
